GOST 3813-72 PDF

Full title and description

GOST 3813-72 — Textile materials. Textile fabrics and piece-articles. Methods for determination of breaking characteristics under tension (procedures to determine breaking load, tear load and elongation at break for textile fabrics using strip and grab methods).

Abstract

This standard specifies laboratory test methods for measuring the tensile (breaking) strength and relative elongation of textile fabrics and textile piece‑articles. It defines specimen preparation, conditioning, test apparatus and procedures (including strip and grab methods), calculation and reporting of results used in quality control, research and regulatory assessments.

General information

• Status: Withdrawn / superseded in parts; historically adopted as an interstate (GOST) standard of the USSR and later amended; elements subsequently replaced by later GOST and ISO documents.
• Publication date: Approved 1972 (introduced into force 1 January 1973); amended subsequently (editions/edits recorded up to 1992).
• Publisher: State Committee for Standards of the Council of Ministers of the USSR (Gosstandart); official publication by Izdatel'stvo standartov (Publishing House of Standards).
• ICS / categories: 59.080.30 — Textile fabrics (textile testing methods / textile materials).
• Edition / version: Original: GOST 3813-72 (1972); amended (edits noted in 1982 and 1992); later partially superseded by GOST 29104.4-91, GOST 29104.5-91 and by adoption of related ISO methods.
• Number of pages: Approximately 20 pages (official booklet collections list the standard within a 20–23 page compendium).

Scope

Applies to raw and finished textile fabrics and piece‑articles made from staple or continuous fibres and yarns. Establishes laboratory procedures for determining breaking (tensile) load, tearing (grab) load and relative elongation at break under controlled conditions; intended for use in production control, materials research and conformity assessment where tensile properties are relevant.

Key topics and requirements

• Definition of test methods for breaking load and elongation using the strip (creep/constant‑rate‑of‑extension) method and a grab (clamp) method.
• Requirements for specimen cutting, orientation (warp/weft), sample size and number of repeats.
• Conditioning of test specimens to standard atmosphere prior to testing and procedures for wet testing where applicable.
• Specification of testing machine type and test speeds (constant rate of extension machines), clamps/grips and calibration considerations.
• Calculations for maximum force (breaking load), relative elongation at maximum force and reporting format (units, averaging, tolerances).
• References and alignment to international standards (IDs with ISO 5081:1977 / ISO 5082:1982 and later equivalence to ISO 13934 series).

Typical use and users

Used by textile testing laboratories, manufacturers (fabric and garment producers), quality control departments, research institutes and regulatory bodies in countries using or referencing GOST conventions (former USSR / EAEU region). Also of historical and technical interest for standards engineers comparing legacy GOST methods with modern ISO/EN procedures.

FAQ

Q: What is this standard?

A: GOST 3813-72 is a Soviet interstate standard (GOST) that specifies laboratory methods for determining breaking (tensile) load and relative elongation of textile fabrics and related piece‑articles.

Q: What does it cover?

A: It covers specimen preparation, conditioning, test apparatus (strip and grab/clamp methods), test speeds and procedures, calculations and reporting for tensile/breaking and tear properties of woven and many other fabric types.

Q: Who typically uses it?

A: Textile test laboratories, fabric and garment manufacturers, standards bodies and technical departments in regions that historically used GOST documents (USSR / CIS / EAEU) and anyone comparing legacy GOST methods to modern ISO/EN standards.

Q: Is it current or superseded?

A: Largely superseded — the document was introduced in the early 1970s and later amended; parts of it were replaced in the 1990s by national GOST replacements (GOST 29104.4-91, GOST 29104.5-91) and, in practice, modern testing often follows ISO 13934 series (strip and grab tensile methods) or updated national adoptions. Check the applicable national/regional registry for current legal/regulatory status.

Q: Is it part of a series?

A: Yes — it is part of the textile test methods series (related GOSTs in the 3810–3813 range and other textile standards). It has normative links to earlier ISO methods (ISO 5081/5082) and later alignment to ISO 13934.

Q: What are the key keywords?

A: Breaking load, tensile strength, elongation at break, strip method, grab method, textile fabrics, specimen conditioning, GOST 3813-72.
