Preface

1 PREPARED by the Limited Liability Company “National Expert Diagnostic NEDC”) based on its own translation into Russian of the English version of the standard specified in paragraph 4

2 INTRODUCED by the Technical Committee for Standardization TC 364 “Welding and related processes”

3 APPROVED AND ENTERED INTO EFFECT by order of the Federal Agency for Technical Regulation and Metrology dated March 31, 2022 N 237-st

4 This standard is identical to the international standard ISO 13920:1996* “Welding. General tolerances for welded structures. Linear and angular dimensions. Shape and location" (ISO 13920:1996 "Welding - General tolerances for welded constructions - Dimensions for lengths and angles - Shape and position", IDT).

________________ * Access to international and foreign documents mentioned in the text can be obtained by contacting the User Support Service. — Note from the database manufacturer.

This International Standard was developed by Technical Committee for Standardization ISO/TC 44, Welding and related processes, subcommittee SC 10.

When applying this standard, it is recommended to use, instead of reference international standards, the corresponding national standards, information about which is given in the additional appendix YES

5 INTRODUCED FOR THE FIRST TIME

6 REPUBLICATION. March 2022

The rules for the application of this standard are established in

Article 26 of the Federal Law of June 29, 2015 N 162-FZ “On standardization in the Russian Federation”
. Information about changes to this standard is published in the annual (as of January 1 of the current year) information index “National Standards”, and the official text of changes and amendments is published in the monthly information index “National Standards”. In case of revision (replacement) or cancellation of this standard, the corresponding notice will be published in the next issue of the monthly information index “National Standards”. Relevant information, notices and texts are also posted in the public information system - on the official website of the Federal Agency for Technical Regulation and Metrology on the Internet (www.gost.ru)

1 area of ​​use

This standard establishes general tolerances for linear, angular dimensions and for the shape and location of welded structures, related to four classes of tolerances used in normal precision work. The main criterion for choosing an accuracy class should be the operating requirements of the product.

In all cases, the tolerances indicated on the drawing apply. Instead of specifying individual tolerances, tolerance classes corresponding to this standard may be used.

The general tolerances for linear and angular dimensions, shape and location established in this standard apply to welded structures, assemblies, etc.

For structures of increased complexity, special conditions may be applied.

The specifications given in this standard are based on ISO 8015, in which dimensional and geometric tolerances are applied independently of each other.

Manufacturing documentation that defines tolerances for linear and angular dimensions, shape and location should be considered incomplete if references to general tolerances are missing or these references are incomplete. These requirements do not apply to intermediate sizes.

6 Tests

6.1 General provisions

The testing and measuring devices and instruments used must be suitable for the purpose and have the required accuracy:

— certified steel rulers;

- measuring tapes;

- rulers;

- squares;

— calipers (in accordance with ISO 3599 and ISO 6906);

— measuring instruments with a dial scale (in accordance with ISO/DIS 463).

By agreement, other testing and measuring instruments can be used.

Measurement results may be affected by temperature and atmospheric conditions, for example when taking measurements on large structures under intense sunlight.

The actual angle values ​​should be determined by placing appropriate measuring instruments on the surface of welded structures at a distance from the weld. The magnitude of the deviation should be determined as the difference between the nominal and actual size. Angular deviation can be measured in degrees and minutes or in millimeters per meter.

6.2 Straightness

The edges of the welded product and the ruler must be positioned in such a way that the greatest distance between the ruler and the surface of the product is minimal. Measure the distance between the ruler and the edge of the product (see Figure 6).

Figure 6 — Straightness test

6.3 Flatness

The actual surface of the welded product and the measuring plane must be installed in such a way that the distance between them is minimal. This can be achieved through the use of, for example, optical instruments, tubular water levels, tension cables, surface plates, decks and frames.

Measure the distance between the actual plane of the product and the measuring plane (an example of measurements is shown in Figure 7).

Figure 7 — Flatness test

6.4 Concurrency

The reference surface must be installed parallel to the reference plane. The measuring plane should be installed parallel to the reference plane and at some distance from the welded structure, using the measuring instruments listed in 6.3. The distances between the actual surface and the measuring plane are measured (an example of measurements is shown in Figure 8).
