GOST 11701-84 PDF

Full title and description

GOST 11701-84 — Metals. Methods of tensile testing of thin sheets and strips. National (USSR) standard that specifies methods for static tensile testing at (20 ±15/−10) °C of thin metallic sheets and strips (up to 3.0 mm thick) to determine tensile properties such as proportionality limit, yield (physical and conventional), ultimate tensile strength, and elongation characteristics.

Abstract

This standard defines specimen selection, preparation, test conditions and measurement procedures for tensile tests of thin ferrous and non‑ferrous metal sheets and strips. It provides requirements for test-piece geometries, gripping, crosshead speed (strain rate), test environment (room temperature), and calculation/reporting of results (limits, strengths, uniform elongation, elongation after fracture). GOST 11701-84 includes Amendments No.1 and No.2 and was intended to harmonize testing of sheets and strips (≤3.0 mm) across factories and laboratories.

General information

• Status: Introduced as a State Standard of the USSR; replaced the earlier GOST 11701-66 and issued with Amendments No.1 and No.2. Its formal expiration date was extended/adjusted by subsequent decisions; it remains a recognized historical/testing reference (check national registry for current national replacements).
• Publication date: Approved by decision 17 July 1984; date of introduction into force 1 January 1986.
• Publisher: USSR State Committee for Standards (Gosstandart of the USSR) — State Standard of the USSR. Later stewardship and references handled by successor standards bodies and interstate councils.
• ICS / categories: Metallurgy — mechanical testing of metals; classifier section commonly shown as 77.040.10 (mechanical testing of metals).
• Edition / version: GOST 11701-84 (original 1984 approval / 1986 introduction), with Amendments No.1 and No.2 (amendments approved in the late 1980s–early 1990s) and a 1993 reprint incorporating amendments.
• Number of pages: Typical published document length varies by edition and format (commonly shown as approximately 10–15 pages depending on print/pdf edition).

Scope

Applies to static tensile testing of thin metallic sheets and strips (thickness up to 3.0 mm) at ambient temperature to determine tensile properties used for material specification, quality control and mechanical-characteristics reporting. The standard covers specimen cutting and preparation, choice of specimen geometry, test-machine and grips requirements, test speeds, measurement methods and calculation of results.

Key topics and requirements

• Definitions and terms for tensile properties (refers to GOST 1497-84 for terminology).
• Specimen types and dimensions for thin-sheet and strip testing (proportional flat specimens and recommended gauge lengths).
• Requirements for tensile testing machines, grips and extensometers appropriate for thin specimens.
• Specified test temperature (nominally 20 °C with stated tolerances) and preparation/conditioning of specimens.
• Recommended crosshead speeds / strain-rate regimes for different gauge lengths and thicknesses.
• Procedures for measuring and reporting: proportionality limit, yield (physical and conventional), ultimate tensile strength, uniform elongation and elongation after rupture.
• Rules for calculating results, acceptance of test data, and methods for handling irregularities (necking, slippage, fracture outside gauge length).

Typical use and users

Used by metallurgy and materials testing laboratories, quality control departments in sheet‑metal production, mechanical and structural design engineers, certification bodies and research institutions that assess the mechanical properties of thin metallic sheets and strips for production control, specification verification and failure analysis.

Related standards

Key normative references and related documents include GOST 1497-84 (terms and specimen preparation), ST SEV 471-88 (interstate agreement for sheet/strip testing of certain thickness ranges), and subsequent or parallel national and international tensile-testing standards (for example, ISO/EN tensile test standards such as ISO 6892 series used internationally). Later national GOST R / interstate standards and test-method updates may supersede or supplement some provisions; users should consult the current national registry for official status.

FAQ

Q: What is this standard?

A: GOST 11701-84 is a Soviet-era State Standard that specifies methods for static tensile testing of thin metal sheets and strips (up to 3.0 mm thick) to determine mechanical properties such as yield, tensile strength and elongation.

Q: What does it cover?

A: It covers specimen selection and dimensions, specimen preparation, test-machine and gripping requirements, test conditions (including temperature and speed), measurement methods and calculation/reporting of tensile properties for thin sheet and strip materials.

Q: Who typically uses it?

A: Metallurgical and materials testing laboratories, sheet‑metal manufacturers, QA/QC engineers, certification bodies and designers who need standardized tensile-property data for thin metallic materials.

Q: Is it current or superseded?

A: GOST 11701-84 was approved 17 July 1984 and introduced 1 January 1986; it replaced GOST 11701-66 and was issued with Amendments No.1 and No.2 (late 1980s–early 1990s) and reprinted in 1993. Its formal expiration/validity was addressed by later interstate decisions (validity-extension measures in the 1990s). Because national/regional standards have been revised since the USSR era, users should verify the current legal/technical status in the national standards registry (Rosstandart or interstate council) before using it as a binding normative reference.

Q: Is it part of a series?

A: It is part of the family of metallurgical testing standards and cross-references terminology/specimen rules (e.g., GOST 1497-84). Related series include other GOST and GOST R standards on mechanical testing of metals and international equivalents (ISO tensile test standards).

Q: What are the key keywords?

A: Tensile testing, thin sheets, strips, metals, yield strength, ultimate tensile strength, elongation, specimen, tensile method, GOST.
