5. Incoming control

5.1 The order of the incoming control:

1. Checking the availability of quality certificates of the company (manufacturer);
2. Checking the integrity of the packaging of electrodes, fluxes and wires, etc.;
3. Checking the compliance of electrodes, fluxes and wires with the requirements of specifications (technical conditions);

For materials that have passed the incoming inspection, an act on the results of the inspection of products must be drawn up with an entry in the incoming inspection log.

5.2. Storage of welding consumables

In accordance with the manufacturing requirements, welding consumables should be stored in conditions that prevent moisture and guarantee the safety and tightness of the package.

Electrodes, flux-cored wire, solid-section welding wire, fluxes in a sealed package with centralized storage in a specially equipped room can be stored without additional checks for one year.

If the packaging of the electrodes is leaking or damaged, then the electrodes should be subjected to additional verification of their properties and used first. Such electrodes are not subject to further long-term storage.

Store the welding wire in dry warehouses in the original packaging. Each batch of wire must have a certificate indicating the manufacturer, its brand, diameter, heat number and chemical composition... Each coil (coil) of wire must be attached with a tag indicating the manufacturer, the number of its heat, the brand and diameter of the wire in accordance with GOST 2246-70.

The wire supplied by import must be in coils with a row winding of rectangular cross-section weighing not more than 30 kg, placed in a double package "polyethylene + cardboard box".

The fused welding flux should be stored in dry warehouses in sealed factory packaging (multi-layer kraft paper bags or metal containers). The package must indicate the manufacturer, the brand of flux, the number of GOST or technical conditions, weight, batch number.

Each batch of flux must have a certificate indicating the manufacturer, flux grade, batch number and acceptance characteristics (composition of the flux, bulk density, grain size). If the package of the flux is damaged, it should be placed for storage in a sealed container, on which it is necessary to indicate the brand of the flux, the batch and certificate number, the plant (company) - the manufacturer.

It is forbidden to mix fluxes of different brands, delivery lots and manufacturers.

Coated welding electrodes of basic type, packed in carton boxes covered with a heat-shrinkable film must be calcined before welding at a temperature of 350-380 ° C for 1.5-2 hours, followed by placement in thermostats. If, for any reason, the calcined electrodes have been in an unsealed container for more than 8 hours, they must be re-calcined. Re-calcination is allowed up to 5 times with a total calcination time of no more than 10 hours.

Basic coated, packed in sealed metal cans, should not be calcined before welding. However, if the electrodes from an open metal can have not been used for work shift(~ 8 h), they must be calcined.

Foreign-made cellulose-coated welding electrodes are supplied in sealed metal cans and do not require pre-drying before use.

Open packages with electrodes must be carefully closed during breaks in welding. Under this condition, the electrodes are suitable for welding for 24 hours (at an air temperature of ~ 20 ° C). If the cellulose electrodes for any reason have not been used within this period of time, then they are not subject to further use. The exception is the Lincoln Electric cellulose electrodes. In case of long-term storage on outdoors and excessive moisture, it is allowed to dry them before use at a temperature of 80-90 ° C for 10-20 minutes.

• absence of dents, scoring and other mechanical damage on the inner and
  outer surfaces of pipe bends;
• the absence of dents, nicks and delamination on the ends;
• no damage to the anticorrosive coating of pipes.

When controlling geometric parameters by measurements, check:

• diameter at the ends of the bends;
• wall thickness of the bends;
• ovality of the section;
• bending angle;
• minimum bending radius;
• the length of unbendable straight sections;
• corrugation height;
• the thickness of the anti-corrosion coating.

Defects of the anticorrosive polyethylene coating of pipes and bends are repaired according to the technology given in RD-1390-001 -2001.

Acceptance results are considered satisfactory if the received data on
all indicators meet the requirements of OTT.

6.2. Bend marking

The symbol of the bends should consist of: total bending angle, nominal outer diameter and wall thickness, steel grade (strength class), curve serial number, OTK stamp.

The designation of the branch must comply with the requirements of GOST 24950-81.

To control the linear dimensions of the bends, use metal tape measures (GOST 7502-98) and a metal ruler in accordance with GOST 427-75, as well as vernier calipers and other measuring instruments manufactured according to the standards for this tool.

The length of the bend, together with the straight sections, is determined by the arithmetic mean of the measurements along the convex generatrix on the outside of the curve and along the concave generatrix on the inside of the curve. Measurements are made with a metal tape. Measurement error ± 1 mm.

The bending angle of the curve is checked with a protractor or other measuring devices that allow the bending angle to be measured with an accuracy of ± 10`.

The deviation of the longitudinal weld from the neutral plane of the retraction is measured with a metal ruler along the perpendicular from the longitudinal edge of the bending bed of the machine to the weld.

The ovality of the straight ends of the bends is checked at a distance of not more than 250 mm from the ends of the product according to the maximum difference of two mutually perpendicular maximum and minimum diameters.

The ovality of the bent part is measured in the sections of the first and second bends, in the middle of the bend and in the section of the last bend.

The step for measuring the ovality of the bent part of the bends should be no more than 1 m for bends with a diameter of 720 mm.

To measure the maximum and minimum diameters of the bends, a metal ruler is used, and the bent part is a departmental measuring tool.

The height of the corrugations is measured using a caliper and a metal ruler with a length of not more than 0.3 of the outer diameter of the pipe, installed on the edge along the tops of the corrugations or a single corrugation parallel to the branch axis.

The appearance of the bends is checked visually.

6.4. Insulation coating control of bends

The purpose of incoming inspection is to control the quality of materials, semi-finished products, components and technical documentation. The need for carrying out, the type and plan of control, the list of types of products to be inspected is determined by the consumer enterprise.

Incoming control is carried out by a department of Quality Control Department (incoming control bureau), organizational structure which is determined depending on the scope of work on incoming inspection. The regulation on the incoming control division should define the main tasks, rights and obligations of employees, the organizational form of the control and the rules for relations with other services of the enterprise.

To carry out incoming control of the products arriving at the enterprise, a list of its types, a list of controlled parameters with an indication of the tolerances for them, requirements for measuring and testing instruments, a description of the conditions for conducting control for each parameter are drawn up. Then the technology of control is developed.

The incoming control service monitors the products presented to it and gives an opinion on the possibility of launching it into production.

If the quality of the products does not meet the requirements, then a complaint is drawn up, which is presented to the supplier. Rejected products are subject to isolation pending a decision on the complaint.

Incoming control can be carried out by:

Checks of accompanying documentation, packaging and external inspection of products - if there is a certificate of conformity for the product or the quality system;
- selective statistical control of the receipt of products in batches, the volume of which is sufficient to obtain samples with the established risks of the consumer and the supplier;
- continuous control.

When conducting selective statistical control, one should be guided by the standards:

GOST R 50779.30; GOST R 50779.51; GOST R 50779.50; GOST 18242 GOST 188321.

Well-established accounting and analysis of the results of incoming control allows the consumer enterprise to provide methodological assistance to suppliers in improving the quality of the products they supply.

Control of the accuracy of technological processes.

The purpose of monitoring the accuracy of technological processes is to obtain information necessary for their regulation, assessing the accuracy and stability of technological processes, determining the compliance of the accuracy characteristics of the equipment with the accuracy standards established in the normative and technical documentation.

The control of the accuracy of technological processes can be carried out, both in the process of established production, and when new or repaired equipment is introduced, during product certification, during scheduled inspections, etc.

The accuracy of the technological process can be assessed by the deviation of the actual value of the parameter from the nominal value and by the accuracy and stability coefficients, which are determined in accordance with GOST 16.304 and GOST 16467, as well as the percentage of product delivery from the first presentation, the percentage of return from the shops - consumers and the percentage of complaints and rejects.

As a result of the accuracy control, factors are identified that lead to a violation of the accuracy of the technological process, the significance of the influence of various reasons on the accuracy of the technological process is established, and the limits of regulation of the parameters of the technological process are calculated.

In conditions of serial and mass production, the accuracy control of machining technological processes is carried out in accordance with GOST 16.305, according to which the accuracy of technological operations is evaluated by one of the following methods:

Graphic-analytical;
- evaluating the accuracy for one implementation;
- analysis of dependencies between processing errors in two operations.

Methods for assessing accuracy in the conditions of single and small-scale production are regulated by GOST 16.306, and GOST 16.307 establishes methods for determining the frequency of adjustment of automatic and semi-automatic equipment.

Inspection control.

During the inspection control, the following is carried out:

Systematic assessment of the actual level of product quality, identification of recurring defects, their analysis and elimination of the causes of their occurrence;
- checking the efficiency of the quality control department at various stages of production.

To bring the inspection control, an inspection group is organized as part of the Quality Control Department. The work of the group is carried out according to the plan approved by the head of the quality control department.

The inspection team periodically monitors the quality of products and factors influencing it (adherence to technological discipline, quality of components, etc.). She can conduct tests.

Product testing.

The manufacturer conducts preliminary and acceptance tests of products in order to determine their conformity terms of reference, the requirements of regulatory and technical documentation and the possibility of putting products into production.

To conduct acceptance tests, a commission is appointed, which includes representatives of the customer, the organization-developer of the documentation, the manufacturer and the state supervision authorities.

Based on the test results, a protocol is drawn up, in which the data and results of product tests are noted according to the test program and methodology, an overall assessment of product quality indicators and other data.

In the process of serial production of products, employees of the Quality Control Department carry out control tests (acceptance and periodic).

Incoming control log

During the construction of the facility, it is necessary to carry out incoming quality control of incoming materials and equipment for compliance with those specified in project documentation GOST, TU and other characteristics (for example, integrity, packaging integrity, geometric dimensions, color, frost resistance, water permeability, shelf life, warranty period, etc.), while checking the presence and content of the supplier's (manufacturer's) accompanying documents confirming the quality the specified materials.

The entrance control itself is carried out before the use of building materials. Actually, the very meaning of incoming control is to identify products that do not correspond to the drawing or specifications, to identify defective or low-quality materials.

In clause 7.1.3 SP 48.13330.2011 Construction organization. The updated edition of SNiP 12-01-2004 says that, “The results of incoming control must be documented in the logs of incoming control and (or) laboratory tests.

Incoming control log form

A separate folder is created for quality documents, where they are all filed. You should make entries in the journal in a timely manner so that you do not have to remember later when what was brought. When logging, pay attention to the "Storage Conditions" column.

Some insulating materials, paints are stored only at positive temperatures (in a heated warehouse). Small things (in a closed warehouse). Cement in bags (Canopy). Reinforced concrete products, brick, sand, metal structures (open warehouse). Ready concrete mix, mortar - immediately to work. In the 9, 10 columns, the persons who carried out the entrance control sign.

If the material by some parameters does not correspond to the project, the journal writes "not suitable" and why. The possibility of its application can be tried to be agreed with the Designer and the Customer.

Incoming quality control

Incoming acceptance control should be understood as control of the quality and completeness of products during certification or during the delivery of these products by the supplier, to the consumer (customer) before the start of its transfer to construction or operation.

Why is it necessary to carry out incoming product quality control?

First of all, to assess its compliance in quality and completeness with the requirements of the rules, technical conditions, national standards, as well as the terms of the agreement (contract).

Then with the purpose of timely detection of incompleteness, as well as detection of external, internal or hidden defects in the delivered products.

In order to prevent the launch into production, operation that does not comply with the established requirements, norms and rules, as well as product standards, which, as a result, may lead to an emergency or destruction with harm to human life or health, as well as property, both physical and legal persons.

Types of incoming acceptance control:

Continuous - 100% control of all mass-produced products;
Selective is when a sample or several samples of a product is taken from a batch;
Single is incoming control a certain amount equipment or products that are supplied in batches under contracts (agreements).

Who conducts incoming quality control?

Typically, the incoming acceptance control can be carried out:

Independently by the consumer unilaterally;
the consumer together with the supplier (manufacturer) of the products;
by a third independent party usually attracted by the consumer products " Technical Specialist Customer ";
a certification body, a testing laboratory or an expert organization when performing work related to the issuance of a certificate of conformity.

The technology of the incoming acceptance control?

First of all, it is necessary to develop and, if necessary, agree on a program or methodology (map) for conducting incoming acceptance control, in which it is necessary to determine the methods, parameters and sequence of actions during product control.

Next, you need to decide on the place, date and time at which acceptance control will be carried out, after which a commission should be created, which may include both representatives of the supplier and representatives of the customer, as well as representatives expert organizations and other third parties involved by agreement.

After all the previous steps have been completed, you can safely proceed to the main one, namely, to conduct the incoming acceptance control, which, if necessary, can be divided into several stages, namely:

Acceptance according to the quantity and labeling of products in packaging (in a box, box, container, etc.) without in-package inspection, the so-called acceptance according to a consignment note or packing list;
acceptance of accompanying documentation for products, which, in addition to transport (shipping) documentation, may include technical, operational and permits(certificates, permits, certificates, examinations, etc.) confirming the quality of products;
visual inspection and verification of the completeness of products, performed after opening the package (container);
the final stage is quality and warranty checks, technical characteristics and product parameters. If, for example, this is considered in the context of technological equipment, then this final stage can be performed only after the installation work has been completed and all commissioning tests have been performed.

Note. The decision on the need to introduce, tighten, weaken or cancel the incoming inspection is made by the consumer based on the characteristics, nature and purpose of the product.

Formalization of the results of the completed incoming control?

There are several results: positive, negative and that the product or its individual devices do not partially correspond.

The result of the incoming control is a conclusion or a signed Act (Protocol) that the products correspond in quality and quantity and that the consumer has no complaints. From this moment, the report of the warranty period set by the seller usually begins. In cases where a negative or partially negative act (protocol) on the results of control is drawn up, in this case, at the expense and forces of the supplier (manufacturer), the product or its parts, assembly is refined or replaced in order to achieve positive results during repeated control, or the supplier and the consumer, upon agreement, can establish the procedure for compensation for losses from defective or incomplete products, but again if this is provided for by the terms of the contract or other NTD.

Incoming control act

Registration of the act of incoming control occurs when the delivery of materials or equipment is made to the enterprise. This document is an accompanying sheet on the basis of which the subsequent commissioning of the equipment or the use of materials takes place.

This control, being the most important part of the technological process, to a large extent ensures the smooth operation of the organization, as well as high quality finished products... Thanks to timely inspection, only high-quality materials and equipment are used in the work, thereby significantly reducing the cost of manufacturing goods for the repair and maintenance of production lines.

Incoming inspection allows you to determine the conformity of the quantity, configuration, quality of "incoming" products to the requirements of technical documentation, as well as when identifying flaws, defects, etc. timely file a complaint with the supplier.

Who draws up the act of incoming control

The preparation of this document is carried out by acceptance specialists (engineers, foremen of sections, heads of departments). In order to avoid claims to the content of the act, a specially created commission (two or more people) is involved in its execution, which certify with their signatures all the information entered into the act. Also, under some conditions, representatives of third-party organizations, as well as representatives of the supplier, may be involved in the incoming control.

Equipment or materials supplied must be inspected or tested before this document can be drawn up.

After the control is successfully passed, the authorized employee fills out an act, where he fixes the fact that the delivered products comply with the declared standards, regulations and requirements, and also enters all the information received in a special journal. After inspection, materials or equipment are delivered to Production Department.

If the control is not passed, then the defect is also recorded in the act, and a complaint (i.e. claim) is drawn up to the supplier. Further actions may be different: either the delivered products are returned back, or they are exchanged for a similar product, or they are repaired at the expense of the manufacturer-supplier.

Rules for drawing up an act of incoming control

The acceptance certificate does not have a standard sample, therefore it can be drawn up in free form or according to a template specially developed within the enterprise. This document can be written on a regular A4 sheet.

The document must contain the following information:

The very fact of the entrance control,
its date and place,
result of checking,
complete information about the equipment or materials that have passed the test.

Depending on the complexity of the products supplied, the act can be expanded and include additional items (on packaging, storage conditions, packaging, comments, additions, etc.).

The act is drawn up in one original copy, but if necessary, several more copies are printed (for all interested parties), each of which must be certified by the signatures of the commission members. It is not necessary to certify the document with a seal, because legal entities may not use seals and stamps in their activities.

Instructions for writing an act of incoming control:

At the top of the document, in the middle, its name is written with a short designation of the essence (in this case, "incoming control"), and also the city in which it is created and the date are indicated: day, month, year. Then the full name of the enterprise that received the goods and carries out incoming control is entered (indicating its legal form of IP, LLC, CJSC, OJSC).
Next, we make a list of the commission carrying out the check: the positions, surnames, names, patronymics of employees are indicated.

Let's move on to the design of the main part. Here it is written about what kind of equipment or materials were tested:

Name,
brand,
factory number,
quantity, etc. parameters.

Each product must be listed on a separate line to avoid confusion.

Then the date of receipt is set, and the fact of the absence of flaws, malfunctions and defects, including compliance with the technical documentation, is evidenced.

If there are any claims to the received products, this must also be reflected in this document with a detailed description.

At the end, the act is signed by all members of the commission that inspected and controlled the incoming equipment or materials with mandatory decoding of signatures and an indication of positions.

Incoming control

Products accepted by the quality control department, the customer's representative office, the state acceptance of the supplier enterprise and received with accompanying documentation drawn up in accordance with the established procedure are allowed to the incoming inspection.

When carrying out the incoming control, it is necessary:

1) check the accompanying documents certifying the quality of products and register the products in the logs of the results of incoming control;
2) control the selection of samples or samples by warehouse workers, check the completeness, packaging, marking, appearance and fill out the act of taking samples or samples;
3) carry out quality control of products according to the technological process of incoming control or transfer samples or samples for testing (analyzes) to the appropriate division.

The division that received samples or samples for testing (analysis) carries out the tests in a timely manner and issues to the incoming control division a conclusion on the compliance of the tested samples or samples with the established requirements.

The results of tests or analyzes (physical and mechanical properties, chemical composition, structure, etc.) must be transferred to production along with the tested products.

The products accepted based on the results of the incoming inspection should be transferred to production with a corresponding mark in the accounting or accompanying documents.

Marking (branding) of accepted products is allowed.

Products received from the supplier before the incoming inspection must be stored separately from those accepted and rejected by the incoming inspection.

Products rejected during the incoming inspection must be marked "Defect" and sent to the defect isolator.

Based on the results of the incoming control, a conclusion is drawn up on the conformity of the products to the established requirements and the journal for recording the results of the incoming control is filled out.

In the accompanying documents for the products, a note is made on the conduct of the incoming control and its results, the products are marked (branded), if this is provided for by the list of products subject to the incoming control.

If a non-compliance with the established requirements is revealed during the incoming inspection process, the products are rejected and returned to the supplier with a complaint.

In case of repeated receipt of low-quality products or receiving them in large quantities, the consumer informs about this in territorial body Prosecutor's office at the location of the supplier.

Based on the results of the incoming inspection, the consumer, if necessary, informs the supplier's ministry, the customer's representative office and (or) the state acceptance body at the supplier enterprise, if necessary, informs about the non-compliance of the products with the established requirements, and in the absence of the latter, the territorial body of Gosstandart at the supplier's location to take measures in accordance with those assigned to their functions.

For electro-radio products accepted by the customer's representative office, information is sent to the customer's head institute for these products.

Incoming control of raw materials

Before acceptance, the raw material is weighed (checking the mass of all raw materials), it is allowed to accept raw materials delivered in a standard container (bag) at the nominal mass of a package unit with a random check of the mass of individual packages.

Flour and additives should be accepted from the supplier only if there are certificates of their quality, which should reflect the content of toxic elements, mycotoxins and pesticides, as well as the presence of pathogenic microorganisms. The quality certificate for supplements of animal origin must indicate the presence of antibiotics.

An average sample is taken from each batch of incoming raw materials to control the quality and technological properties of raw materials. Acceptance and selection of the average sample is carried out in accordance with the current regulatory documents for the respective product.

Containers with raw materials received by the enterprise (warehouse) must be clean, dry, strong and meet the requirements of standards. The quality of the supplied main and additional raw materials is checked by the laboratory in accordance with the current regulatory documents.

Incoming equipment control

Incoming control is the very first quality control of the three (input, operational and acceptance), the most routine, large in volume and difficult to execute, since it is most often slaughtered. Before installation, any product, equipment, cable or material must pass the incoming inspection. It will require a percentage of exactly what you have installed and are trying to prove, but it is better to do it for the main hardware and materials at once for the entire volume and not if not before installation, because then there will simply not be time for this. If at the beginning you do not check the cable, the completeness of the equipment, you do not find the documents for this whole thing, then if it is possible, then it is very difficult to do it, do not present any claims to the customer after signing the acceptance papers, but if you did it well and should in the way they have designed, then this is already from a third to a half of the entire performance.

Everything that sits in the specification should be reflected in the incoming control. Also, there must be materials that are not taken into account by the specification (it lays down the VET during the revision of the drawings before the signing of contracts) and everything that is drawn up by additional agreements, official changes (after the contract).

It is done in accordance with GOST 24297-87 Incoming control of products. There is still an unapproved and incomprehensibly developed INSTRUCTION for the registration of the results of incoming quality control of documentation, materials and equipment. There are samples of filling in the VK Transneft magazine.

Karyagin A.G. Materials for electrical work. Second edition, revised (Electrician's Library, issue 520) - Moscow: "Energoizdat";
- Koptev A.A. Installation requirements for electrical equipment and materials (Electrician's Library, issue 539). - Moscow: Energoizdat;
- Gorzon O.F. Guidelines for the transportation, acceptance, storage and storage of materials, products, structures and equipment in construction 2nd edition revised and enlarged.

There you will find a lot of things that you often have to invent when filling out the columns of the VK journal and the absence of normal operational control schemes, for example, "storage conditions" and "controlled parameters".

The main work consists in walking around warehouses, rewriting and seizing documents, after which there is a reconciliation of data and paperwork. All this in order must be done quickly so that later there will be no problems.

Who should carry out the incoming control when the delivery is not ours is a difficult and controversial issue. One way or another, how to carry out and arrange VK will have to performers, i.e. us, but at the same time if they begin to demand an urgent VC, you can gain a little time by the fact that it must be carried out by the customer, or at least in the presence of a representative of the manufacturer if he is not there. We must carry out and formalize our delivery unambiguously.

Incoming control should be done by the foreman or the head of the site together with the foremen and the storekeeper (if any), i.e. he instructs the masters to check everything, and he prepares everything and collects accompanying documents in a heap. This is his job because he signs in the waybills and acts of acceptance and transfer of equipment for installation and then he will write it off according to the VPDM and M-29. If he does not write off, then of course he will not care what came there and how to accept it, he will take anything at random and mount it anywhere just to do it.

Incoming control. During the incoming inspection, the following are mainly checked:

1. Compliance of the supplied cables, products, materials and equipment (brand) to the project;
2. Correspondence of the quantity to the project;
3. Absence of visible defects and damages (appearance);
4. Completeness of equipment or product;
5. Compliance of the product with the technical characteristics specified in the passport or TU, GOST;
6. Availability and completeness of accompanying documentation confirming the type and quality;
7. Date of manufacture according to the passport or marking;
8. The quality of storage.

Compliance of the supplied cables, products, materials and equipment (brand) to the project. Everything that sits in the specifications of the project is divided according to the supply of the contractor and the customer. The entry in the specification of the project "delivery of the customer" does not mean anything yet, it is divided when the contract is signed. Usually, the customer assumes the supply of all complex and expensive equipment, as well as cables over 100m in length, everything else - products, materials and cables up to 100m are supplied by the contractor (if interested, you can take a look at how this is done according to MDS 12-15.2003).

When concluding an agreement with the general contractor, a separation sheet is made and the 10th appendix is ​​signed, according to which the customer completes the object, everything that was not included in this appendix and everything that was missed (forgot to include in its own) is supplied by the contractor. Appendix 10 is made on the basis of the very first isms of the project, which often changes during the construction process, and with it the brand and quantity of cables and equipment. This must be monitored in order to make approvals in time.

The brand, completeness, quantity and technical characteristics of the equipment are checked according to the project in the assignment to the manufacturer. Often in the project there is only a reference to the assignment that comes from the plant along with the equipment, in which case it is necessary to check the compliance of the equipment with the factory assignment or specification. If the brand of the cable or equipment supplied by the customer has at least one wrong letter or there are any differences with the project, you need to correctly draw up a letter indicating what the discrepancies are and reflect this either in the incoming control when everyone has already accepted or not to accept it until the decision comes customer.

Discrepancy between dimensions - width, height, etc. (which is very important when installing in a block-box);
- the cable entry is not there (from the bottom, but should be from the top or vice versa, even if a leaky cover is sent to enter the cable from above, the power cable should not go through the entire cabinet to the connection point, if this is not provided).

Usually no one checks the cable, products and materials supplied by the contractor, you just draw up a VC for the project. How much of this material or products will be for all projects, you can find out from the contractor's delivery list (draws up a PTO in the office). This statement may differ from what was bought in fact due to replacements and approvals that may not reach you at the facility. The complete set makes its summary on the basis of the PTO statement, indicating the exact brands, suppliers and terms, so it will also be very useful, especially if the PTO did not have time to affix the stamps. It is also more convenient to search for documentation, knowing the actual suppliers and having an invoice. If what was brought does not coincide with what should be according to the project, it is better to keep silent about this by falsifying the accompanying documentation, because such things are usually not agreed by the customer and in extreme cases you need to try very hard to convince him that what you delivered or you are going to deliver the quality better or not worse than the design one and that it will be faster and more aesthetically pleasing.

Pay special attention to the boxes. If technical specifications are indicated in the specification for it, then the technical supervision may require a passport in which the same technical specifications must be indicated, and since such cases are often made by the same installation organization, they may not coincide or may not have them at all. The only thing that the institute can agree on is the length of the box, for example, from 3 or 2 meters to 2.5.

Correspondence of the quantity to the project. This is one of the important indicators that is needed primarily by the project manager (site manager, foreman). If the brand came in the wrong place, then it most likely agrees, but if no one compared the quantity on the invoices with the project, then either materials and equipment may simply not be enough, or grab the excess and then it will be necessary to return, because you cannot report to him. At the same time, it often happens that it "went in an unknown direction" and you have to buy at someone else's expense in order to return it. And of course, if no one puts the invoices and OS-15 acts in one place, of course, you will not count anything in principle.

Since there can be many projects for which there may be a lot of this equipment or materials at the facility, a summary sheet is needed to quickly check the compliance with the quantity. When supplied by the customer, you can use the tenth application, but it is better to check it with the latest drawings. Your delivery needs to be checked against the bill of materials delivery, which is done by the PTO, plus the delivery list that the MTS department does for itself. But there can and will be only data that was selected from the specifications, and therefore there is a risk that there will be errors there too. In general, you need to know that when comparing the quantity, it is better to use more accurate data in each specific case. This is a special case for the cable, so it is better to create a consolidated cable journal for it.

No visible defects or damage. First of all, the packaging is examined, if it is intact and it was not hit on the road, then what may have survived inside. Secondly, the appearance of the product itself is checked, the outer turns are inspected on the drum with the cable, the paintwork on the equipment (swelling, scuffs, scratches), the absence of dents and damage. Sometimes, due to poor-quality fastening, the equipment inside the package beats and rubs, and then after a while it stops working, so it's better to document this. All defects in the equipment supplied by the customer must be eliminated by the customer prior to installation. If necessary, for such complex equipment as 110-220 kV transformers, special documentation is also drawn up for inspections of the equipment before unloading and transportation to the installation site.

Completeness. Usually the equipment comes complete, there is a lot of it and you have to deal with the tasks of the manufacturer or the specifications of the plant, check the boxes, compliance packing lists and invoices. This must be done quickly - the customer has strict requirements for the time frame during which it can and should be done. You won't do it yourself, so take the foremen and a couple of workers to carry and open the boxes and check.

Usually there are such jambs when accepting equipment:

Lack of equipment fasteners or cable glands to them;
- the absence of any parts according to the specification, although everything was sent according to the invoice.

First of all, you must have an invoice with the number of seats (railway or road) and you need to check the number of boxes.

Secondly, check the completeness according to the packing lists and the picking list (invoice), whether what was brought with what was packed.

Thirdly, check the picking list (invoice) with an assignment to the manufacturer or factory specification and the availability of all accompanying documentation for the equipment. Often the plant itself agrees upon the complete set, any replacement and sends an agreement with the documentation.

The representative of the manufacturer must be present at the same time and, if necessary, sign the acts. Often he brings with him and you can take a picking list, packing lists and a custom specification in Exel from him, which is very useful. Take his contact numbers and call him in case of any mistakes or lack of documentation, it will be faster than through the customer.

Compliance of the product with the technical characteristics specified in the passport or TU, GOST. This for equipment and cable can only be verified by a laboratory. In theory, before installation, the measuring equipment must be calibrated at the stands, which, as a rule, is not done (they do the operation with the issuance of the necessary protocols). In theory, the manufacturer himself calibrates, assembles equipment at the stands and provides the appropriate documentation for this, and we only check its availability. Sometimes in the standard you find requirements for laboratory control, this is still from old reference books, where factory control was meant (for example, concrete, if done at a factory) when there was still communism and the end-to-end system of regulatory technical documentation extended to them as well. The insulation resistance of the cable must also be checked with a megohmmeter on the drum, even if there is a passport or test report in which these values ​​are indicated, although factory tests with increased voltage are enough for the high-voltage cable (the customer himself must hire a laboratory for this, if there is no factory protocol ). On an optical cable, before laying, technical supervision also requires an OTDR check, even if there are factory passports with reflectograms. In some cases, it is even required to check cable samples (bourgeois).

For a product or material, the geometric dimensions are checked (not by a laboratory): for cable structures (racks, brackets, shelves, trays, boxes and accessories for them), rolled metal and m / structures, the width, height, length, wall thickness are checked; for pipes - diameter and wall thickness.

Availability of accompanying documentation confirming the type and quality. This is the biggest problem in the entire executive and takes up about a third to half of all production documentation. All accompanying documents are of two types - a document issued to the manufacturer by a special certification body that its products are certified for compliance with any standards, or that this product does not need certification.

And a document issued by the manufacturer to the buyer that this product or batch has certain properties and qualities. All are called differently, but the essence is the same. In theory, you should have both. Below is a table of an approximate list of products and the necessary documentation for them.

Certification. In Transneft, all supplied equipment, products, cables and materials must be certified. This means that the manufacturer must certify its products in special centers and receive the appropriate paper - either a corresponding certificate, or a letter stating that this product does not need certification. There are a lot of these certification centers in each region and carry out certification in different systems. It is always easy to find, online or from a supplier, so difficulties arise mainly with passports.

Centers for certification of products and services (by region) issue certificates of conformity in the GOST-R system or a letter (certificate) stating that these products are not subject to certification in this system (refusal of the need for certification). Needed, in theory, absolutely everything.

The Ministry of Communications issues a certificate in the communications system (CCC). Needed for cable and equipment, which are carried out at facilities subordinate and associated with communications.

EMERCOM of Russia issues a fire safety certificate (FSC). It is needed for flame retardant (ng) and LS cable (Lou Smoke - emitting little smoke), for cable ducts and PVC pipes, for equipment and devices responsible for fire safety, which are carried out according to the work of subordinate firefighters (APT, AGT, GPT , PS, SOP, SGO).

federal Service for environmental, technological and nuclear supervision issues permits for the use of explosion-proof equipment on the territory of the Russian Federation. It is needed for all explosion-proof equipment.

The State Sanitary Epidemiological Service (by region) issues a sanitary and epidemiological conclusion. It is needed first of all for products that have direct contact with people or somehow not well can influence them ( Construction Materials which may emit radiation, portable devices, etc.)

Type approval certificate for measuring instruments. Issued for measuring bourgeois equipment.

The declaration of conformity, which is issued by the manufacturer himself (if issued by the certification center, that is another matter) that his products meet some technical conditions along the way does not mean anything, but sometimes there is nothing but it.

The ISO quality management certificate is also not quoted along the way, because so far no one separately requires certification in this system, although you need to look at what exactly it is given and by whom.

Separate components for products are usually not prescribed in certificates (goes for everything that falls under the nomenclature number).

What kind of products in which system should be certified, it is not possible to write for sure, this can be seen on the official sites of certification bodies and sites of organizations producing products. They also begin to produce all kinds of lists of products subject to mandatory certification.

In theory, the institute should design in Transneft, taking into account that the products used are certified, which sometimes does not correspond.

The presence of only one certificate is not even half the battle, it can be downloaded from the net or requested from the customer, but the documentation issued by the manufacturer to the customer can be lost and it is very difficult to find it if lost.

The manufacturer in the certificate must match the factory in the passport if both documents are required.

The documentation issued by the manufacturer or supplier is also varied and depends on the product being manufactured. This documentation is more complicated, it is issued for a product or batch with serial numbers, seals or stamps of the Quality Control Department and dates of manufacture. Therefore, it is more difficult to find if you have lost and difficult to “do”. Demand these documents in the first place, because certificates of conformity, etc., are nonsense that can always be found.

For materials or products (metal or HEV products) there must be quality passports (certificates), which would indicate the name and brand of the product, the date of issue and the batch number, the TU or GOST number.

If the product has any separately applied coating (usually rolled metal or metal structures), for example zinc, then there must be a document on galvanizing (protocol or act, as well as a certificate from the factory that he has the right to do this).

For wiring accessories (boxes, sockets, simple lamps), cable fittings (lugs, tags, etc.), usually the passport is a label and you do not need to attach it, or one label per batch of products, i.e. only a certificate or a letter of refusal of the need for certification is attached to the incoming control.

Cable. On a drum or coil with a cable there must be a marking or label indicating the serial number, brand, number of cores and cross-section, voltage, construction length, month and year of manufacture, TU or GOST, drum type, OTK stamp and manufacturer. They are different for each manufacturer, they are paper, metal or plywood. If there is nothing other than this, then sometimes you have to copy these labels and attach them along with the certificate.

There should also be an insulation test report, which can be combined with a passport or other tests, on which everything that is on the label or marking of the drum is duplicated.

There must also be an overvoltage test report on the power cable. For optical - a protocol or a passport of the characteristics of an optical fiber with reflectograms, the insulation resistance can also be indicated there.

The communication cable, depending on its type, must also have test documents. Equipment. The measuring equipment must have certificates or protocols of calibration.

If the equipment is complex and must be assembled, then assembly drawings or instructions for assembly or installation, as well as a pre-assembly protocol, are required. For what and what should be in the operational documentation, see GOST 2.601-2006. There must be a passport, in which either on the protocols for the equipment there must be data on the tests.

Bourgeois. Manufacturers (bourgeois) do not issue passports for bourgeois equipment, products and cables and a label with data is nailed on the product itself: brand, serial number, date of manufacture, and manufacturer, therefore, it is often necessary to attach such installation instructions (label) or simply indicate in the input control serial number.

Documentation on foreign language must be translated into Russian and if you looked through it during the check, you will be forced to translate everything for delivery.

The required certification, translations into Russian and tests, preliminary assembly with a formalized protocol or act (if needed) must be carried out by the supplier. Sometimes a supplier issues one form for a system of such equipment, which contains technical data and certificates for the whole bunch of imported equipment. In other cases, you must have papers for all the components of the complete equipment. A bourgeois cable must have technical characteristics and test methods, while high voltage tests (if the cable is high-voltage) are carried out by suppliers, or the customer (depending on whose delivery) must hire a laboratory on site to do this before laying.

The date of manufacture on the quality document should not be overdue, and the validity period of the certificate (at the time of manufacture) should not be expired.

The Transneft system has the following requirements:

1. Equipment, products, materials or cables must be manufactured no later than one year prior to installation;
2. Also, at the time of purchase or delivery of products, all certificates must be valid (usually they are given to the plant for 3 years).

Many checking the dates on quality documents - the main remark, of course, from the expiration of the fire certificate, the cable cannot catch fire, but the above condition must be observed (the expired certificate will pass if the date of manufacture is on the passport, when this certificate was still valid and this passport is less year at the time of installation).

Warehousing quality. Warehousing, depending on the need, is covered and open, which is reflected in the incoming control log (Transneftevo). Basically, a special temperature regime (which is usually prescribed for a set of automation) and the absence of atmospheric precipitation are necessary only for special equipment, everything else is closed in containers just so as not to steal.

Sometimes the technical supervision finds fault with the absence of any product in the register of TU, ​​TT and PMI of Transneft, such as it was bought from the wrong supplier. You can’t do anything here, raise the issue at the planning meeting and let the top management change policy, but it’s very difficult to persuade the suppliers to buy from outsiders. Therefore, acquire this register, passports and certificates of exactly those manufacturers who are indicated there and fake. You can delay time by convincing the technical supervision that this register is made for internal use by Transneft's equipment, and not for the contractor, then when you assemble everything, it will be too late to stop work and find fault with its non-compliance, which you will eliminate by making the documents.

For some domestic equipment, such as switchgear, disconnectors for KTPB and other equipment pre-assembled at the stands, assembly protocols are needed, sometimes it even happens that only what such protocols were used for is assembled. Organize the seizure of factory documentation in the warehouse before it gets to the object, especially when it comes to the line, because if you ask the masters or do not ask them, they will still be lost or thrown out. Talk about such a need with the manager of the facility, explain that there will definitely be problems with delivery or interest if this is not done.

For very expensive, bulky equipment, transportation documents sometimes have to be drawn up.

Where to find the customer's delivery documentation. If the general contractor did not receive the equipment or the cable supplied by the customer correctly, and then tries to transfer it to you in the same way, do not sign anything until you check it, let him be responsible for it too. The documentation is handed over to the contractor separately with an invoice or an act of acceptance and transfer of equipment for installation, or it must be looked for in boxes with equipment (in drums with a cable). If the customer tells you that all the documentation is there, but it is in boxes or in drums - do not believe it, do not sign anything, where it is indicated that the documentation is all included and do not let your supplier or foreman sign it. On the invoice or in the act, you can add "the documentation has not been verified" if they are trying to force you to urgently sign something. If there are problems with the equipment package or cable lengths, the supply or the foreman will have problems, but if there are no documents for this matter, you will have problems. Therefore, never sign yourself and do not allow someone else to sign in a jump by knocking out the pen of the document on the acceptance of the equipment or cable without completely checking the availability of all the documentation. You can argue to the customer that the documentation came in one copy, but they can demand two from you, it is better to voice this so that the customer decides to take it in one, than then copy folders of 100-300 passports.

Demand the documentation for the cable from the customer, he must give you all of it according to the above table, some one document or label from a drum or unwinding does not mean that you have it all in the kit. If the customer says that there is a drum - go with him to the drum, open it (take a pry bar) and look on the inside of the drum cheek, on the outside under the plank, at the end of the cable, and sometimes even in the hole for the "pencil" (storekeepers shove if dropped). If there is no document on the quality of the plant in it, indicate it in the invoice. In addition, on the power cable (above 6-10-35 kV) there must be a test report with an increased voltage, without it it is not supposed to lay, and if laid - "it will not seem a little" after laying.

There are tags nailed on cable drums. These are small pieces of plastic, wood or paper wrapped in cellophane with cable data, sometimes even with blue stamps. But these are not passports and not a test document. Depending on the manufacturer, there are no tags, and all the data is painted on the drum cheek. There should also be papers with data on the cable and the tests performed, they are called differently: passport, quality certificate, certificate of quality or quality, document or test report, protocol, etc.

Podolskkabel usually does not nail passports either on the front side or inside, but sends it with an invoice (quality certificate) and if you didn’t bring it separately, you don’t need to look on the drum - you will not find anything except one plastic or wooden tag (inside there is the same tag called a passport , this is also nonsense).

Tomskkabel nails the passports on the front side, so it is better to remove them immediately, replacing them with tape with a piece of paper with data on the brand, cable length and drum number, because nothing is visible on the tag.

On the bay, usually a tag hangs on a string with the batch number and data on the cable, very rarely a passport with test data comes with it, so it is better to remove the tag right away by gluing your piece of paper with the data on top.

The customer can and does so that the chain of transfer of products and documentation for it “manufacturer-customer-general contractor-contractor-operation” is cut off at you and you are ultimately responsible for the quality and absence of anything after signing the documents. Therefore, the most important thing is not to miss the flash and check the completeness in time, do not sign anything, and write letters if something goes wrong.

The absence of this or that document can be drawn up with an act on the results of the verification of products (in the column accompanying documentation indicate that it is absent and, if possible, which one), unless of course someone else signs it besides you, if you signed it, you can present this document with a letter of claim to the customer (after he naturally will not sign this). When all the documentation is found or requested, issue a new act retroactively or accept this documentation by the same act (this is allowed).

If you attach a copy of the customer's delivery document, then be prepared for the fact that the inspectors may require you to certify this copy by the customer, therefore, when taking the certificates from the supplier, make sure that he does not do this right away - the certificate will be needed again, and the certification of the certified copy should be done not pretty, you'd better do it later.

Be sure to remove non-standard keys from cabinets and equipment boxes by hanging a signed tag from which it is.

Technical documentation of manufacturing plants (passports, operating and installation instructions, assembly documentation, software for installed equipment and spare parts). In theory, this is not entirely executive production documentation, sometimes entries are made in it (in forms, etc.) or adjustments to the schemes.

If you lose this at the beginning or during the production of work, then there will be problems. Sometimes the customer himself is responsible for completing and commissioning the technical documentation for the equipment, even before they wrote that he should do this (this can be written in the contract or in the list of design and estimate documentation). In principle, if their delivery, and they check for themselves the completeness of the documentation, then why not do it in one piece (like they are afraid that the contractor will lose, and they do it right). But, as a rule, agents from the customer try to shift it to the contractor or general contractor (by the way, we can shift it to the general contractor if they have people specially for this). This documentation will receive special attention from the operation, since it is they who need it first of all. Technical documentation must be complete for all equipment, translated into Russian (by the customer or supplier), if it is bourgeois, folded separately for equipment and sets. As for translations, it is better to agree in writing in the contract or other documents, because the customer at first is silent or tries not to raise the issue, and then does not accept it for delivery without them.

When receiving any documentation, make a register and sign the act for the documentation specifically for this register, so you will protect yourself if this register does not contain everyone necessary documents.

Pulling out the documentation from the boxes with equipment or from the cabinet, also put everything in separate packages (then in folders), be sure to indicate on it where the documentation is from (for example, the number of the cabinet or cell).

Immediately put all of it in separate folders, and sign them on what equipment, project and PID they are, this documentation, so as not to understand later (then you will not figure it out for sure). If the documentation is compiled by the supplier in a folder, it is better not to disassemble it, but leave it as it is.

Often the documentation is attached to the equipment itself, do not lose it during installation and assembly, making a round of the object, more often look into cabinets, drawers, inspect equipment in search of such documents (usually tied in plastic bags). Get into the habit of picking up all the pieces of paper from the ground at the facility (only at the facility), also check empty containers and packaging from equipment, empty drums - there may be passports and labels that have not been taken out. At one object, I found passports for a cable prepared for wiping in the toilet, who knows why it is needed when there is a lot of toilet paper next to it.

As a rule, there are twice as many technical documentation of manufacturing plants for equipment as folders with production documentation. There are two ways of its delivery - with all the acceptance documentation or separately to the operation representative (power engineer, ACS engineer, overhead line and ECP foreman). If you immediately decomposed it, checked the completeness of its availability and made the registers, then it will be convenient to hand over this bunch of folders along with the entire design and estimate documentation before you prepare the production and there will be fewer comments to you that you don’t hand over anything at all. But it is better, of course, to hand it over separately, in view of the fact that they may be required to make copies of all this, while checking both its completeness and the availability of translations from the bourgeois.

Where to look for the contractor's delivery documentation. A lot of materials have to be bought locally in the nearest city, for example, metal, hardware, every little thing, this should be monitored and required from the supplier immediately when he brings something without quality documents and then periodically remind him, refreshing his memory. When he brings a bunch of passports and certificates, saying, I handed everything over and then don’t say that I didn’t give anything, demand an invoice or invoice and check it. Usually, the suppliers themselves do not know what actually should be from the documentation for any product, they do not require it from factories or suppliers, and they, in turn, provide a certificate of conformity or a letter of denial of the need for certification. Print out and give the supplier in the teeth of the above plate, explain that there are two types of documentation and there must be both, let it work. A lot of materials are taken directly at the facility from the builders (either bought, or borrowed, or simply taken), you, in turn, should not miss this moment and find documentation for this matter from the general contractor or subcontractors, so have good relations with everyone on construction site. Periodically visit the general contractor and look through thick folders with certificates and other papers in search of the documentation you need: channel, pipe, fittings to it, electrodes, steel sheets, all sorts of profiles, paint, brick, sand, etc. (they have everything).

If the product or material came directly from your base, office or other facility, immediately check the documentation, if not - sound the alarm, call the supply, clearly demand what you want from him, if it does not work - call your team leader, to other facilities (there may be similar) or directly to the plant (by way of delivery or invoice). Warn the head of the site that without this you will not see interest. If the storekeeper lost the documents, then these are problems of the assembly, to which he obeys, if the documents are lost by the master, then these are the problems of the foreman or the head of the section, but only if it became known in time, otherwise in all cases of loss it will be your problem.

If none of the options passed - “look for” the papers. Climb in the net in search of certificates, manufacturers usually post them for review. As a rule, most documents come either with an expired date, or the brand is a little different, or GOST or TU are not the same. For this, from each object I carry with me whole databases of scanned certificates, passports, Paint and other useful programs. Take data for searches about manufacturers from labels and plates. In general, this business takes most of the time.

Certification of copies. Only copies need to be certified, and a document with blue seals and signatures does not need to be certified.

If a document confirming the type and quality of your delivery products, then it is better to attach a copy (such as the organization has such a policy). So it is more convenient and unnecessary questions like: "Why is there a copy, and there is an original?" the auditors will not have, the more you may have many such identical documents for different projects (subobjects). If the document is supplied by the customer, then it must be certified by the supplier or, in extreme cases, by the customer. Copies of these documents necessary for different projects must also be certified by the customer, so if you take a copy from the customer, do not immediately certify it, so that you can then duplicate it and certify it from him (a copy of the copy looks ugly). Also, some documents of small size that cannot be stitched and numbered in a folder are better for copying.

You do not certify the document with the “copy is correct” stamp, but make the inscription easier for yourself, therefore there should also be a blue round stamp or a special stamp for this matter. According to GOST R 6.30-2003, clause 3.26: “When certifying the compliance of a copy of a document with the original, below the requisite“ Signature ”, a certification inscription is affixed:“ True ”; the position of the person who certified the copy; personal signature; decryption of the signature (initials, surname); date of assurance. It is allowed to certify a copy of the document with a seal determined at the discretion of the organization. "

Therefore, only the one on whom this seal is written can be certified, i.e. who has a power of attorney, and all sorts of signatures of VET engineers with simple stamps "COPY IS TRUE" are not valid, although they often fail.

Presentation of results. After collecting the necessary information about the work begun and completed on certain projects, start making VC m / structures and HEV products. It is better to issue VC for the delivery of the customer after the fact as it should be, so that later there will be no complaints against you.

The VK act (act on the results of the verification of products) only confirms the conformity of the product to the design documentation, GOST / TU and the presence of accompanying documentation confirming the type and quality of the product. Defects detected immediately upon acceptance, or during the commissioning process are drawn up in another document.

The form of the act, if there is no sample in the list for these types of work, take as a basis the "Act on the results of the inspection of products" in form 3.3 VSN012-88 part 2. In principle, this act is current and is not included in the execution according to the list, but if you do not have it, problems may arise (as a rule, I attach it to the execution). For such types of work as PS, SOP, SOP, SGO and the secret police have their own VK act (for equipment and devices) - according to Appendix 3 RD 78.145-93, issue them additionally for equipment and devices. There is also an act of acceptance of electrical equipment for installation, Form 3.8 VSN012-88 Part 2, this act is needed to complete the ECP equipment for picketing the route, which is not required at a local facility, so immediately get rid of it. Never change the form and text of the act, its interlinear translations, do not add anything to the form templates, if you have a strong urge and this does not contradict the BCH, cross it out and add it by hand or directly in the email - this is allowed. Fill out the template of the act in the e-mail, print it in the necessary copies, attach documents on the quality of the product to them, sign it with everyone, and only after that you can fill out the VK magazine. At the same time, do not put passports and manuals on the equipment (limit yourself with certificates), but indicate them in the act and put them in separate folders.

In the name of the product, indicate its name (abbreviated) and brand (completely), preferably as indicated in the specification, because often the specification lists for example: Power cable with copper strands, with insulation and sheath made of PVC compound, flame retardant ... 0.66 kV, 4x6 mm2 (VVGng). Enough "cable VVGng 4x6 0.66 -400 m". Due to the fact that Transneft along the way began to prohibit design institutes from advertising the products of plants by prescribing brands in it, for which a separate person sat (although they require the acquisition, taking into account the list of technical specifications and PMI of Transneft), you just need to register the brand of the product that you bought to the object, and not as written in the specification of the analog type.

Put the volume either on the volume according to the project specification or on the volume that came. Some materials or products are the same for several projects, in this case, put the volume that is indicated in the specification. If a cable of the same construction length came for several projects, set the construction length (because this length is indicated in the passport or test report, in principle more is possible - less is impossible).

You write the unit of measurement either the same as in the specification, if in fact it is the same, or the same as in the invoice, but in total.

Sometimes some equipment or products (when there are no separate documents for this) can be combined by the input control with what there are documents for (such as a set), but it is better not to do this.

Materials and products. It is possible to combine different materials, products or structures in an act if they have a common TU or GOST. For example, in one act, you can register racks + shelves + brackets of prefabricated cable structures; trays or boxes with lids and corner sections. Separately, for hardware for them, I also try not to draw up anything and, if they are indicated in the specification, I write a tray or box in the kit.

If the length of one product does not coincide with the design one (for example, a BNT100 pipe or a box), then you can arrange the total length in meters without indicating the length of a specific product as in the specification (in pieces), while accessories (covers, connectors, partitions, hardware) write included, and other brands (branches, turns, rises, descents of the box) in pieces.

Equipment. The act prescribes the factory or serial number (if it is spelled out in the accompanying document). Similar equipment (by brand) is issued in one act (listing all serial numbers).

If the equipment is transferred as a "set" in the name is written the same way, but added "according to the attached statement", in which you describe this set in full and attach to the act. Sometimes it is very convenient to draw up this way if you have not found all the accompanying documents for each part of the set.

If there is a lot of accompanying documentation, you also write it down in the statement, and in the sections about the accompanying documentation it is also written "according to the attached statement of the accompanying documentation." The statements are compiled in a form approximately like a register, only instead of a page according to the list, write the number of sheets or copies, they are signed and attached to the VK act. Documentation according to the statement is filed in a separate folder with the registration of the register based on the statement.

In principle, for the delivery of the customer, the act on the results of the verification of the product or the VC act is not the main one, this is transferred by the act of acceptance and transfer of equipment for installation. The cable is designed for each construction length (drum, coil or unwinding) according to the brands and number of cores, i.e. in one act, you can issue only one brand of cable (several drums are possible).

Documents needed:

Certificate of quality / conformity (comes with an invoice or downloads from the Internet);
- Passport or factory protocol for checking insulation resistance (comes with a drum, the paper usually contains No.bar, there is an OTK stamp).

In the absence of the head. of the protocol, data over the cable is copied from the drum and the protocol is forged.

The construction length must be entered into the act according to the drum numbers, or a rewind or a b / n bay is written.

The contractor's supply cable (usually there is not a lot of it in the contract) is sometimes grouped from all specifications into total lengths and one protocol is forged per face-to-face length (within reasonable limits). The "made" protocol is copied to subobjects and a VC act is drawn up for each subobject with a length according to the corresponding specification / statement (like we were equipped with one drum - less gemar).

The customer's delivery cable is drawn up strictly on the drums after signing the delivery note to the contractor (although no one can check - the waybills are not filed in the ID).

Also, when receiving and arranging the customer's supply cable for low-current networks, it is necessary to look at the lengths of the cable lines according to the cable magazine so that the construction length of the cable (on a drum or unwinding) is enough for one or more line lengths, i.e. taking into account that there are no couplings (in automation and AFC this is unacceptable, although it is done constantly), if necessary, write a letter about this.

The protocol for examining and checking the resistance of the cable on the drum before laying is usually done on the same day as the VK act (usually immediately together with the VK act).

Everyone who participates (signs VK - acts and magazine) must have a VIC certification with copies of certificates and protocols in the permits, although, as a rule, such a certificate will be sufficient for the person exercising control.

The VK act is signed by:

Quality control representative;
- Contractor;
- Technical supervision (often does not sign in the line where the Customer is indicated in the form of the act, but signs at the bottom of the type "confirmation of the VK procedure") if it is proved that this is it.

Keep VK logs according to the design (as well as completing general magazines), so you will have to redo less and there will be less confusion.

Fill it out on the basis of the signed acts. Fill in the column "controlled parameters" according to technological map for incoming control, and if there is not enough information, or it is not there, on the basis of the product passport or operation manual. In the column "Results" write the number of the act, according to which it was done and the word "corresponds". Now the inspectors pay more attention to the magazine, and not to acts on the results of the verification of products, because they are not required according to the list.

The head of the site or the foreman and foreman signs in the magazine. Sometimes in the VK magazine (it is necessary to clarify) in the position “controller” it is signed “NOT OUR”, although, as a rule, a representative of the construction control of the general contractor or from our side who has a VIC is enough.

All materials, products, cables and equipment, both the contractor's and the customer's deliveries, must pass the incoming inspection in full according to the specification, including spare parts and accessories (even for what was not and will not be in fact). The main thing is that the VC takes place earlier or on the same day of installation (on papers), so check everything. Sometimes the specification does not include sand for the bed and powdering the cable in the trench, but according to the project it is required - calculate the approximate amount and make a VC for the entire volume or divide it into several parts for persuasiveness (for a technical supervisor).

Defect registration. The detected equipment defects are detected either during the acceptance of the equipment (visible) and are reflected in the act on the results of the verification of products and in the VC log. Or in the process of its installation and commissioning, it is carried out with a representative of the manufacturer (otherwise the plant may not accept the claim).

Therefore, find out immediately if it is possible to open equipment boxes without a manufacturer's representative. The act is filled out in the OS-16 form. If you have issued it, everyone knows about it, and you are going to attach it to the ID, then there must be an act on the elimination of these defects, if it does not exist, then it is better not to attach OS-16 to the ID.

Usually, the customer immediately draws up an act on the identified defects, in which they write that everything is fine, in full, together with the documentation, but this act is also needed to formalize the identified defects during the installation and commissioning process (which cannot be immediately detected) according to the Resolution of the State Statistics Committee of Russia No. 7. So the customer will not be excused from defects if they were not identified during the incoming inspection.

Very often something goes wrong, with defects or without documentation. A lot of things can be corrected on the spot, and whenever possible, this is always done. If these jambs then definitely do not float up and it will not hang on the installers (since there were no defects, then there was a jamb in the installation), then it is better not to raise the buch, but to do it as they say. If there are risks that the jambs can hang on us, then it is better to arrange it as it should be. You can issue an act on the results of the verification of products, including the absence of accompanying documentation. An act of detected defects can and should be issued for defects that could not be detected immediately, but only during testing and commissioning (non-working equipment, etc.). In the VK log, you can indicate that it is suitable for installation after checking for the presence of missing accompanying documentation, and then conduct a separate VC for the documentation that came. Or it is generally not suitable for installation if the defects are critical.

Incoming document control

At the entrance control working documentation a check should be made of its completeness and the sufficiency of the information contained in it for the production of work.

The drawings and estimates received for the construction must be registered in special magazines of the general contractor.

Requirements for the composition and completeness of working documentation for new construction and reconstruction of existing structures are determined by sections 3 and 4 of chapter SNiP 1.02.01-85.

In accordance with clause 3.1 of the chapter of SNiP 1.02.01-85 and clause 7.9 of the chapter of SNiP 3.01.01-85, design organizations-developers should include lists of:

Types of work for which it is necessary to draw up certificates of inspection of hidden works;
- critical structures subject to acceptance during construction.

Working drawings and organizational and technological documentation (POS, PPR) must be registered in a special journal.

Accepted documentation is sent to the construction site with a mark "For work execution" and signed by the chief engineer.

Departure from the working drawings of the erected structure and auxiliary structures and devices issued by the customer for the production of work, caused by the clarification of the conditions for the production of work, is allowed only by agreement with the customer and the design organization with the introduction of appropriate changes to the working drawings.

At the incoming control of working documentation, the check is carried out by employees of the technical and production-technical department of construction organizations. Comments on design estimates and organizational and technological documentation are drawn up in the form of an opinion for presentation through the customer to the design organization. Documentation accepted without comment is transferred to the construction site with due account.

At each construction site, it is necessary:

Maintain a general work log in the form given in Appendix 6, special logs for certain types of work, the list of which is established by the general contractor in agreement with subcontractors and the customer, and the designer's supervision log of design organizations (if any);
- draw up certificates of inspection of hidden works, intermediate acceptance of critical structures;
- draw up other technical documentation provided for by SNiP for certain types of work, and executive documentation- a set of working drawings with inscriptions on the compliance of the work performed in kind with these drawings or changes made to them in agreement with the design organization, agreed by the persons responsible for the construction and installation work.

The general work log is the main primary production document, reflecting the technological sequence, terms, quality of performance and conditions for the production of construction and installation works.

A general work log is kept on construction (during reconstruction, expansion) of individual or groups of the same type of structures under construction at the same time located within the same construction site. In the construction of artificial structures included in the title of a railway line or highway, a general journal can be kept for a group of simultaneously erected small bridges under the supervision of one contractor.

When building medium bridges, as well as large bridges, a general work log must be kept at each site.

During the construction of large bridges that have work sites drawn up by order, a general journal is allowed to be kept at each construction site. The general work log is kept by the person responsible for the construction of the facility (work supervisor, senior work supervisor) and fills it out from the first day of work at the site personally or instructs the shift managers to complete it.

The title page of the magazine is filled in before the start of construction by the production and technical department of the subdivision.

The list of engineering and technical personnel employed in construction is made by the head of the department.

Table 2 of the journal provides in a calendar order a list of all acts of intermediate acceptance of critical structures and survey of hidden works of an object under construction. This list should be drawn up by the production and technical department together with a representative of the design organization, taking into account paragraphs. 1.32. and 1.34 "Manuals"

Table 3 magazines - "Results of operational quality control of construction and installation work" includes all work in parts and elements of structures, the quality of which is controlled.

Tab. 4 - "List of special work logs" is filled in by the person responsible for maintaining the general work log. It contains the names of special journals and the names of the persons responsible for their maintenance. After the completion of special work, for example, assembly work, a note is made in the table about the delivery of the magazine with the signature of the official who handed in and received the magazine.

Regular information about the production of work (from the beginning to the end), included in the table. 5 - "Information about the production of work" - are the main part of the journal. It should provide information about the beginning and end of work with a reflection of the progress of their implementation.

The description of the work should be carried out for all structural elements of the structure as it is erected, indicating the place of work in height and location on the plan with reference to the axes and with reference to the working drawings. It should also provide brief information on the methods of work, the materials used, products and structures, downtime of construction machines (indicating the measures taken), deviations from working drawings (indicating the reasons) and their approval, changing the location of security, protective and signal fences, relocation of transport and fire passages, laying and dismantling of temporary engineering structures, the presence and implementation of operational quality control schemes, the results of geodetic instrumental checks during operational quality control, data on corrections or alterations of the work performed with an indication of the culprit, as well as on meteorological and other special production conditions works. If the journal is issued for a group of bridges, the records should be kept for each structure separately. In the magazine issued for large and medium bridges, it is recommended that the description of the work be carried out separately for the enlarged structural elements with the allocation of the required number of magazine pages for each element.

Work on the construction of temporary structures, as well as preparatory work, are recorded in the journal by start and end dates.

Table 6 of the magazine - "Statement of receipt of technical documentation" - the person responsible for maintaining the journal records the numbers of drawings and other documents received from the production and technical department to the facility.

Table 7 of the magazine - "Remarks of the regulatory bodies and services" are made comments of persons who control production and safety work in accordance with the rights granted to them, as well as authorized representatives of the design organization or its designer supervision. The general work log must be laced, drawn up with all signatures on the title page and sealed with the signature and seal of the building organization that issued it.

Manufacturers of works of construction and installation organizations and the customer's representative are obliged to record in the designer's supervision log the execution of the instructions of employees of design organizations exercising designer supervision. The head of the general contractor or a responsible representative of the organization appointed by his order is responsible for the timely and high-quality fulfillment of the requirements of the designer's supervision, as well as for the safety and maintenance of the journal in proper form. After the facility has been put into operation, the general contractor must hand over the designer's supervision log to the customer.

Data on the production of certain types of construction and installation work should be entered on a daily basis in the appropriate special journals provided for by the current chapters of SNiP and listed in this "Manual".

Special work logs are issued to the managers of the production and technical department of construction with a completed title page and indicating the number of laced and numbered sheets. The magazine must be registered and, upon issue, signed by the head of the organization that issued the magazine. The logs received for production are stored during the execution of work by the persons responsible for their maintenance, and during breaks - by the heads of the sections.

New magazines can be issued only after the delivery of completed magazines in the prescribed manner, which are the main documents presented at the commissioning of objects.

When filling out the work logs, it must be borne in mind that entries in them should be made either directly at the place of work, for example, when driving piles, shells, sheet piles, or at the end of a shift when maintaining shift logs for certain types of work.

It is prohibited to keep draft records on separate sheets, notebooks, etc. with the subsequent rewriting of data into the log.

See the relevant chapters in the Manual for instructions on how to keep a log. When the completed construction of the facility is put into operation, the general and special work logs are presented to the working commission and, after the facility has been accepted for operation, they are transferred to the custody of the customer or on behalf of the operating organization.

Certificates of inspection of hidden works and acceptance of critical structures are drawn up taking into account the instructions in the subsequent chapters of the "Manual".

Each act must be assigned a number, which must correspond to the number according to the list of the general work log.

Incoming inspection of pipes

Incoming inspection of pipes and fittings should be carried out in accordance with the requirements of SNiP 3.01.01.-85.

During the incoming inspection of pipes and fittings, a check should be provided for:

1. Pipe size;
2. Number and date of technical conditions;
3. Steel grade;
4. Batch number;
5. Results of mechanical tests with indication of which heat numbers the test data refer to;
6. Results of hydraulic tests;
7. The result of the X-ray examination (if necessary).

On the inner surface of each pipe, at a distance of 500 mm from one of the ends, the marking should be applied with indelible paint:

Manufacturing plant;
heat number;
nominal dimensions;
pipe number;
month and year of manufacture of the pipe;
carbon equivalent.

On the outer surface of the pipes, at a distance of 100 mm from the end of the pipe, the following data should be stamped with stamps:

Pipe number;
the brand name of the plant.

After checking the conformity of the use of pipes for a given construction according to the certificate, a visual measurement control is carried out.

The following are not allowed on the pipe surface:

Cracks, flaws, sunsets of any size;
scratches, risks and scuffs with a depth of more than 0.4 mm;
local kinks, corrugations and dents;
delamination at the ends of the pipes.

If delamination is found, then, according to the results of additional ultrasonic testing, the ends of the pipes with delamination must be cut out. In places affected by corrosion, the wall thickness of pipes or parts should not go beyond the minus tolerances established by the delivery specifications. Measurement of the wall thickness in this area must be performed using an ultrasonic thickness gauge with an accuracy of at least 0.1 mm.

Pipes are considered suitable provided that:

Less than 200 mm from the end is not exceeded for pipes with a diameter, see GOST 10705-80, 20295-80.3262-75, etc.
deviations of the wall thickness at the ends do not exceed the limit values ​​regulated by the corresponding GOST 10705-80,20295-80,3262-75, etc.
the ovality of seamless pipes does not bring their outer diameter beyond the limit deviations, GOST 10705-80,20295-80,3262-75, etc.
the curvature of pipes does not exceed 1.5 mm per 1 m of length, and the total curvature is not more than 0.2% of the pipe length, the oblique cut of the pipe ends does not exceed 2.0 mm.

It is allowed to clean on the surface of pipes and parts of scratches, marks and scuffs with a depth of more than 5% of the thickness, as well as areas of the surface affected by corrosion, provided that the wall thickness after the elimination of defects will not go beyond the established tolerances.

It is allowed to correct smooth dents at the ends of pipes with a depth of no more than 3.5% of the pipe diameter. The straightening should be carried out with impactless expanding devices. At an ambient temperature below 5 degrees. C, and on pipes of strength class 42 and higher - regardless of the ambient temperature, straightening should be performed with mandatory heating at 100 - 150 degrees. WITH.

It is allowed to repair pipe edge defects (nicks, seizures) by welding with a depth of no more than 5 mm, followed by mechanical cleaning of the places for correcting defects until the required bevel of the edges is restored.

Sorting of pipes is carried out by representatives of the construction and installation organization, customer, technical supervision of the customer.

An act is drawn up for the rejected pipes, which should contain the following data:

Name of the supplying plant;
Diameter and wall thickness of pipes;
Steel grade;
Certificate number, pipes, heats;
Date of receipt of pipes and time of their inspection;
The exact name of the detected defects, their configuration and location;
The possibility of using pipes for this construction.

Pipe quality control does not end with an inspection at the unloading site. Pipeline monitoring continues throughout the entire pipeline construction period.

When accepting pipes with a factory insulating coating, the condition of the coating is also checked by a visual method, and, if necessary, by an instrumental method (using a spark flaw detector).

Upon detection of damage, an act is drawn up, which provides the following data:

Place and date of inspection of pipe insulation;
Pipe number and defect location;
Defect type (depth, area).

Incoming control results

Based on the results of the incoming control, it is recommended to draw up a conclusion on the conformity of products to the established requirements and fill out a log of the results of incoming control.

The controller must carefully check the data of the control, analysis or test protocol with the technical documentation for the product and in the accompanying documents for the product make a note about the incoming control and its results, mark (mark) the products, if this is provided for by the list of products subject to the incoming control.

If the product meets the established requirements, the incoming control division makes a decision on transferring it to production.

If a defect or incompleteness of the delivery of products is detected, the incoming control division draws up an act for the marriage or incompleteness of the delivery.

The supplier company, having received a complaint, conducts the necessary research into the reasons for the non-compliance of the product with the requirements of the regulatory and technical documentation, agrees with the consumer and sends the consumer a research report indicating the measures taken to eliminate the reasons noted in the complaint with a conclusion about the effectiveness of the measures taken.

Quality control department must systematically inform the supplier about the results of incoming inspection.

The supplier, in agreement with the consumer, develops and implements measures aimed at improving the quality of products.

Based on the data on the actual quality level of the supplied products, accumulated by the incoming control division, OGK, OGT, OMTS, etc., the Quality Control Department makes proposals in the prescribed manner to improve the level of its quality and, if necessary, revise the regulatory and technical documentation.

Proposals-applications for the revision of the normative and technical documentation of the valley have marks: "according to the results of the incoming control".

In the event of rejection of products in the shop at the supplier's shop (latent defect), a defective act is drawn up, according to which the products are sent to the defect isolator along with defective acts signed by the heads of the shop and the master of the incoming control unit.

Responsibility for defects arising from products that did not pass external acceptance or were rejected by the Quality Control Department are borne by the workers of the warehouses who gave the order to issue these products for production.

Based on the results of the incoming inspection, the consumer, if necessary, informs the territorial body of the State Standard of Russia at the location of the supplier enterprise about the non-compliance of the product with the established requirements for taking measures in accordance with the functions assigned to them (Appendix 2, GOST 24297).

incoming control warehouse goods

Incoming control should be understood as a set of measures to assess the quality of products arriving at the enterprise and intended for use at hazardous production facilities.

Materials, components and equipment cannot be approved for use in the absence of documents confirming the quality of their manufacture and compliance with regulatory and technical requirements.

Incoming control is an element of the industrial safety system.

The purpose of incoming control is to establish the conformity of product quality with the established requirements of the Rules for safe operation facilities of the enterprise, regulatory requirements for products.

Incoming control is of three types: output (acceptance), interoperational and incoming control - checking raw materials and components for compliance with standards and quality requirements. Conducting a continuous analysis of the quality of materials and raw materials supplied to the enterprise, allows you to achieve high quality products.

Incoming control happens:

· Selective - a check of several product samples from a batch for quality is carried out, based on the results of which a conclusion is made about the quality of the entire batch;

· Solid - all products are tested without exception;

· Statistical - preventive, carried out according to the technological process, and its main purpose is to prevent the likelihood of marriage.

In the course of the check, the grade of the product is taken as a measure of the quality of the product, namely, the qualitative classification of the product according to the indicators (or one indicator) that are established by the standards. Some varieties of goods are not classified by grade, but are determined as unusable and suitable. Classification of products by grade is carried out most often by the presence or absence of defects in appearance and less often by other deviations. External defects, in turn, are divided into unacceptable and acceptable. Products with defects that are unacceptable are rejected. Permissible defects and their number are stipulated in the standards for a particular type of product.

The main tasks of incoming control:

Obtaining a high probability assessment of the quality of goods submitted for inspection;

Ensure unambiguous recognition of the results of quality control of goods by both the supplier and the consumer, carried out according to the same test methods and plans;

Establish the conformity of the quality of goods to certain requirements, so that in case of their non-conformity, to submit claims to suppliers on time, as well as to carry out operational work with suppliers to ensure the normal level of quality of goods;

To prevent the launch of products for repair or production that do not meet the requirements, standards, and also do not comply with GOST.

Incoming control is subject to products, raw materials and materials accepted by the supplier's quality control department and received by consumers in the presence of accompanying documents drawn up in the appropriate manner. If the accompanying documentation certifying the appropriate quality of goods and their completeness is absent, and they are necessary for production needs, their use is allowed after agreement with the design department after tests have been carried out that the goods correspond to the domestic standard technical documentation and an act on the actual completeness and quality of goods is drawn up, and missing documents are also indicated in the act.

All goods, raw materials and materials received from the supplier, until the inspection, must be stored separately from other, rejected or accepted products. The check can be carried out at the time of receipt or when the product is put into production, the main thing is that its warranty term does not expire. If the shelf life of the product has expired, it must be rechecked, even if it has been tested and tested before. Only after this can a decision be made on the possibility of its further use in production.

The need to introduce, weaken, cancel or tighten incoming control is accepted by the consumer, based on the characteristics, purpose and nature of the product, based on the results of inspection for the previous period, or its consumption (operation). During the inspection, rejected goods are marked as defective and stored in a special isolator until the issue is resolved between the consumer and the supplier.

The consumer, if necessary, can carry out additional checks of goods that are not provided for by the NTD for the goods, while if the modes and conditions specified in the methods for conducting additional checks do not exceed those established in the NTD for the goods. In this case, the methods do not need to be agreed with the supplier and the consumer. If additional checks show a negative result, no complaint will be made to the supplier. An additional check by the consumer makes it possible to identify potentially unreliable elements for a given type of product and to reject them in advance. Also, when checking products from a supplier, it is permissible to train them in the modes and conditions that are provided for by the NTD. This must first be stipulated in the list of products.

Incoming control of goods includes checking:

The quality of the products supplied;

Availability of established accompanying documents that certify the completeness and quality of products;

Verified products are registered in special accounting journals.

Based on the results of the inspection, the consumer either allows further use of the product, or, if the product does not meet the requirements, informs the territorial subdivision of Gosstandart of Russia at the place where the supplier enterprise is located for further action.

Depending on the composition of hazardous production facilities at the enterprise, a list of products subject to incoming control must be drawn up. For typical products, it is recommended to draw up standard plans (schemes) and types of control, on the basis of which individual plans and types of control can be drawn up for products with specific requirements.

In a detailed form, the list may contain:

a) the name and type of products, including those subject to mandatory certification;

b) a list of regulatory documents, the requirements of which must comply with the product;

d) monitored parameters or clauses of regulatory documents in which these parameters are established;

e) means for measuring parameters and the availability of these means at the enterprise or at the services involved;

f) the warranty period for the use of products;

g) instructions on product labeling based on the results of incoming inspection;

h) permissible quantitative consumption of products (from a batch) when using destructive control methods (consumable resource).

The implementation of incoming control must be ensured:

a) a complete set of regulatory documents for the relevant types of products;

b) control and measuring equipment and instruments, test benches with the provision of their timely metrological verification in accordance with the requirements;

c) test methods based on the requirements of the relevant standards or manufacturer's instructions for test equipment and instruments;

G) standard plans control for certain types of products;

e) the presence of certified specialists for the appropriate type of control.

Incoming control is carried out according to the parameters (requirements) established in the regulatory documents for the products. Incoming control of products according to parameters not specified in the regulatory documentation, as well as in contracts (contracts) for the supply, can be carried out by the enterprise for its own purposes without agreement with the supplier, but without the right to make claims against the supplier.

In cases of disagreement with the supplier in assessing the quality of the product, the incoming inspection should be performed according to agreed methods.

Based on the purpose of the incoming control, the enterprise can carry out it both at the stage of receipt at the warehouse, and immediately before use for its intended purpose, however, within the warranty period and only for those points of the requirements of regulatory documents that are important for a particular type of product.

Products stored in warehouses must be provided with conditions for the safety of their technical characteristics. In case of direct use, a repeated incoming inspection must be carried out in a limited scope: verification of documentation, visual inspection.

Organizational forms of incoming control are based on existing forms organization of the production process and involve, depending on the type of controlled product, the following functional divisions of the enterprise:

OMTS - department of material and technical supply;

OKO - equipment assembly department;

OKS - capital construction department;

OGM - department of the chief mechanic;

OTN - department of technical supervision;

OGE - department of the chief power engineer;

Instrumentation and controls - instrumentation department;

LIST - testing laboratories, including non-destructive testing methods, and stands for testing equipment and devices;

RMP - repair and mechanical production;

SMiO - warehouses of materials and equipment;

YUS - legal service;

SVED - service for foreign economic activity;

TPU - technological production and installations.

The options for organizing these units, their administrative subordination, and the functions performed at a particular enterprise may be different.

When developing a system of incoming inspection of an enterprise, it should be borne in mind that the possibilities for controlling various products are limited, and the possibilities of external acceptance of certain types of products directly at manufacturing enterprises should be used, especially for complex and with special requirements of products, which should be stipulated in the supply agreement. Works on incoming quality control of products can be transferred to the service departments of the enterprise, independent specialized organizations or certified laboratories on the basis of an agreement.

When developing the functions (responsibilities) of performers, one should also provide for the target dates for the performance of certain types of work on incoming control.

The main task of incoming control is to prevent the use in the manufacture, installation, repair and reconstruction of technical devices used at a hazardous production facility, materials, components and equipment that do not meet the requirements of regulatory and technical design documentation.

Incoming control is carried out according to the parameters (requirements) and methods established in the normative-technical and / or design documentation for the controlled products and materials, as well as according to the approval protocols for the supplied products.

Based on the results of the incoming inspection, decisions are made about the suitability of products for use or their rejection with the presentation of claims to the supplier or transport organizations.

The technological tasks of incoming control of products arriving at the enterprise are:

a) checking the availability of the accompanying documentation provided for in the ND (permits for use, certificates of conformity for products subject to mandatory certification, certificates for materials and components, passports, instructions, drawings, picking lists, packing lists);

b) checking the completeness of the data provided in the accompanying documentation for compliance of these data with the requirements of rules, standards, technical conditions and the requirements of design documentation, special requirements included in the contract for the supply of products;

c) checking the completeness of the received materials for compliance with supply agreements, packing lists, picking list and drawings; checking the integrity of the packaging and preservation;

d) checking the presence of factory markings and its compliance with the data of the certificate or passport for the product, as well as the requirements of state or industry standards;

e) carrying out visual and measuring control of materials and products in order to identify possible surface defects, damage, as well as to check the compliance of geometric dimensions and form deviations with the requirements of regulatory documents and supply contracts;

f) checking the properties of materials and parts certified in the quality document by non-destructive and destructive testing methods in the volumes of a statistically reliable sample or arbitration sample in accordance with GOST, TU or other regulatory documents;

g) registration of the results of incoming control and transfer of information about the quality of materials and products to interested services and divisions of the enterprise;

h) timely execution of relevant documents for materials and products that have defects identified during the acceptance process and notify suppliers within the time frame established by law or agreement (contract) about the non-compliance of the supplied products or equipment with the requirements of ND and the application of sanctions to suppliers provided for by the agreement;

i) control of the issuance of materials and products of the required quality for the production of work;

j) accumulation of data on the actual level of quality of the products obtained, development on this basis of proposals for its improvement and, if necessary, revision of the requirements of regulatory documents or proposals for the selection of suppliers;

k) periodic monitoring of compliance with the rules for storing products and carrying out loading and unloading operations;

l) registration and storage of the results of incoming control.

Organizational forms of incoming control should focus on minimizing document circulation and, if possible, on using computer technologies in the preparation, processing and storage of incoming control documents.

During incoming inspection, both generally accepted documents (acceptance certificates for the quantity and quality of products, warehouse accounting logs, warehouse registration cards, consignment notes for the movement of goods, conclusions on product testing) and newly introduced documents (technical requirements, incoming control card, route map of movement of samples for testing product quality).

In the absence of an administratively dedicated incoming control service at the enterprise, the performance of functions and tasks of incoming control is assigned to a permanent commission, the composition of which is formed by an order for the enterprise.

If necessary, the work of the commission includes OGE specialists, instrumentation and automation specialists, an uninterested person (a representative of a third-party organization), representatives of other services of the enterprise, a supplier's representative, if this is stipulated by the contract.

For an instrumental assessment of the quality of products arriving at the enterprise, subdivisions of the enterprise or third-party organizations that are able to perform necessary work: visual measurement control, non-destructive testing, chemical and spectral analysis metal, mechanical testing, metal science and corrosion testing, testing of welding materials, testing of equipment and devices at stands.

To ensure an appropriate level of incoming control, preparation for it should be carried out at the stage of formation by departments, workshops (technological units) of the enterprise of applications for the necessary materials, products and equipment. From the shop orders, the OGM forms a consolidated application that takes into account the technical requirements of individual applicants. The basis for the formation of technical requirements for materials, products or equipment are GOST, TU, requirements of technical specifications for equipment, requirements of Rostekhnadzor rules for the design and safe operation of relevant products, requirements for design or repair documentation and other regulatory documents. In some cases, it is possible to present more stringent requirements for products than is stipulated by the regulatory documentation. When developing technical requirements, it should be borne in mind that most standards and other regulatory documents have hierarchical system constructions, since they have links to other documents in the text.

When generalizing shop orders and forming an order for an enterprise (OGM, OKO), as well as at the stage of legal preparation of agreements (contracts) for the supply, technical requirements should be included in the contract as an integral part of it. At the same stage, it is advisable to draw up a map of the incoming control with an indication of the controlled parameters. After agreeing with the supplier of products and drawing up a supply agreement, the Technical Requirements and the Incoming Control Card are transferred to the product acceptance services (OMTS, OKO, OKS).

In some cases, the agreement (contract) should include a requirement for the supplier to accept products by the customer directly at the supplier's production facility, or on the presence of the supplier when accepting products by the customer. This is especially true for complex and critical equipment, products with increased or special requirements and cases where there are no proper controls. In this case, the incoming control procedure must be agreed with the supplier when concluding the contract.

At the stage of acceptance of products in terms of quality, the chairman of the incoming control commission calls representatives of the technical services of the enterprise, who, on the basis of the incoming control card and technical requirements, perform the necessary amount of work, including determining the necessary representative sample from the received batch of products, marking the control points and cutting samples for the necessary tests or research, draw up a product control route map, which indicates the shops, sections, services of the enterprise that cut out blanks for samples (RMP), manufacture and mark samples, test and study samples (laboratories), as well as where the controlled products should be returned after cutting out blanks or samples, after bench tests (for storage, for restoration, disposal or other needs). The control route map serves the purposes of organizing and tracking the passage of the incoming control procedure for a specific batch of products.

Products arriving for cutting of blanks and samples, as well as samples for testing, are registered in the logs of receipt of samples of the incoming inspection of the corresponding subdivision-executor. The logs indicate the registration number of the product, the nature of the task, the marking of the tested samples and the final results (conclusions) of the work.

To perform typical work on cutting and examining samples, the executing units must have appropriate instructions. The basis for the development of instructions and forms for the performance of a particular type of work and the issuance of conclusions are the corresponding GOST, TU and other regulatory documents, taking into account the peculiarities of the equipment and devices available at the enterprise.

The results of visual measurement control and testing of samples are entered into the incoming control card with the signatures of the performers. After checking the data of the incoming inspection with the data of the technical requirements, the commission makes a decision on the conformity / non-conformity of the products with the technical requirements. In case of conformity of products on the certificate (passport) of products, a sign or a stamp “Incoming control passed” is affixed with the signature of the chairman of the commission, a corresponding note is made in the registration card for issuing products. Delivery of products from warehouses to divisions of the enterprise according to consignment notes is carried out only in a marked form and complete with a product quality certificate or a passport for the supplier's products. In case of non-compliance of products with these technical requirements, the commission for incoming control draws up a substantiated act of acceptance of products in terms of quality, which is sent to the management of the enterprise for making decisions on the presentation of legally justified claims or complaints to the supplier.

Figure 1.1 Flowchart of incoming product inspection operations (recommended)

Thus:

In case of non-compliance of products with these technical requirements, the commission for incoming control draws up a substantiated act of acceptance of products in terms of quality, which is sent to the management of the enterprise for making decisions on making legally justified claims or complaints to the supplier;

If the supplier does not agree with the results of the customer's incoming inspection, an expanded commission is created with the obligatory presence of a representative of the supplier's enterprise. Where necessary, arbitration tests of products are carried out;

In the event that the manufacturer eliminates the detected defects and carries out additional control, the products may be accepted;

The products received by the divisions of the enterprise from the warehouses must be registered in the registration cards of materials and products of the division together with a product quality certificate and stored in compliance with the rules for storing products of the corresponding type in conditions that do not allow re-grading. The issuance of products for the manufacture of products, repair or installation work is carried out only after verifying the certificate data with the requirements of the technical documentation for the production of work. A similar requirement must be met by third-party organizations performing work at the facilities of the enterprise with their materials and products;

Upon completion of work on incoming control, the incoming control card, technical requirements and route map remain stored in the department that carried out the acceptance of products.
