GOST 7564-97 PDF

Full title and description

GOST 7564-97 — Rolled products. General rules of sampling, rough specimens and test pieces selection for mechanical and technological testing. Establishes procedures for selection of samples, preparation of blanks and specimens used in tensile, impact, bending and related mechanical tests of rolled metal products.

Abstract

This interstate standard defines general requirements and methods for taking samples from rolled-metal products (bar, section, sheet and strip, and shaped sections), preparing blanks and machining test specimens, and specifying orientation and location of specimens relative to the rolling direction. It is aligned with international practice for selection and preparation of metallic test specimens.

General information

• Status: Adopted interstate standard (introduced as a state standard of the Russian Federation); replaces GOST 7564-73.
• Publication date: Introduced 1 January 1999 (designation year 1997).
• Publisher: Adopted by the Interstate Council for Standardization, Metrology and Certification; introduced by Gosstandart (State Committee for Standardization of the Russian Federation).
• ICS / categories: Metallurgy / rolled products; ICS code indicated as 77.040 (metallic materials / testing).
• Edition / version: GOST 7564-97 (original 1997 designation), introduced 1999-01-01; text notes an amended edition (September 2009).
• Number of pages: Approximately 15 pages in standard publication.

Scope

The standard applies to rolled metal products and sets out general rules for: selection of samples from production lots; preparation and treatment of blanks (including thermal or mechanical operations where required); cutting and orientation of test specimens for tensile, impact (Charpy) bending, upsetting and cold-bend tests; and minimum sample sizes and locations to ensure representative mechanical and technological testing. It is intended to be used where specific product standards do not set alternative sampling or specimen preparation rules.

Key topics and requirements

• Rules for selection of samples from different product forms (bars, wire, sheets, strips, wide strip, and shaped sections).
• Orientation and location of specimen extraction relative to rolling direction and product geometry.
• Minimum sample sizes and provisions to allow repeat testing.
• Preparation treatments for blanks (mechanical straightening, thermal treatment, machining allowances) and restrictions to avoid altering material properties.
• Specification of specimen types and dimensions for tensile, impact bending, upset and cold-bend tests, referencing relevant test-method standards.
• Normative references to related test standards (tensile, impact, bending, elevated-temperature tests) which govern specimen dimensions and test procedures.

Typical use and users

Used by steel and non-ferrous rolled-product manufacturers, quality control and metallurgical laboratories, inspection and certification bodies, product designers and purchasers who require defined, reproducible rules for sampling and specimen preparation for mechanical testing of rolled metal products. Also used as a reference when a product-specific standard does not specify sampling details.

Related standards

Normative and related references cited in GOST 7564-97 include national test standards for metals such as GOST 1497 (tensile), GOST 7268 (impact aging), GOST 8817 (upsetting), GOST 9454 (impact at various temperatures), GOST 9651 (tensile at elevated temperatures), GOST 11701 (thin sheet tensile) and GOST 14019 (bend test). The standard is noted to comply with international standard ISO 377-1 (selection and preparation of samples and specimens for mechanical testing) in the scope of sampling and specimen preparation.

FAQ

Q: What is this standard?

A: GOST 7564-97 is an interstate/state-level standard that sets general rules for selecting samples, preparing blanks and cutting test specimens from rolled metal products for mechanical and technological testing.

Q: What does it cover?

A: It covers where and how to take samples from different types of rolled products, how to prepare and treat blanks (including thermal and mechanical treatment restrictions), specimen orientation relative to rolling, minimum sample quantity for repeat tests, and references to the specific test-method standards that define specimen dimensions and test procedures (tensile, impact, bending, etc.).

Q: Who typically uses it?

A: Steel mills, rolled-product manufacturers, QA and metallurgical testing laboratories, inspection and certification bodies, and technical purchasers who need standardized sampling and specimen-preparation rules for mechanical testing of rolled metal products.

Q: Is it current or superseded?

A: GOST 7564-97 replaced the earlier GOST 7564-73 and was introduced as a state standard on 1 January 1999. The available bibliographic records indicate an amended edition noted in September 2009; users should verify with the national or interstate standards body for the very latest status or any subsequent replacements.

Q: Is it part of a series?

A: It forms part of the family of standards governing mechanical testing of metallic materials and rolled products and cross-references multiple GOST test-method standards (tensile, impact, bending, elevated-temperature tests). It is classified under metallurgy/testing ICS categories and complements product-specific standards that set mechanical requirements.

Q: What are the key keywords?

A: Sampling, rolled products, test specimens, blanks, tensile, impact, bending, specimen orientation, metallurgical testing, GOST 7564-97.
