GOST 19712-89 PDF

Full title and description

GOST 19712-89 — "Изделия трикотажные. Методы определения разрывных характеристик и растяжимости при нагрузках, меньше разрывных" (Knitted garments — Methods for determination of breaking characteristics and extensibility under loads lower than breaking). The standard specifies test methods used to determine tensile (breaking) characteristics, extensibility at sub‑breaking loads, residual deformation and seam extensibility for knitted articles.

Abstract

This interstate (GOST) standard establishes laboratory procedures and requirements for preparing specimens, conditioning, and performing tensile and extensibility tests on knitted garments and knitted textile articles (except hosiery and gloves where excluded). It provides measurement principles used in quality control, certification and research of knitted products.

General information

• Status: Active / In force (period of validity restriction was lifted by MGS protocol; the standard remains in effect).
• Publication date: Adopted 1989; effective from 1 January 1991 (entered into force).
• Publisher: Gosstandart (USSR) / Interstate standard (Межгосударственный стандарт).
• ICS / categories: Clothes / textile testing — OKS/ICS classification: 61.020 (Clothes); classification group M49 (methods of testing for knitwear).
• Edition / version: Original designation 19712-89 (1989). Amendment No.1 adopted in the 1990s; reissue published (with amendment) in later reprints.
• Number of pages: 16 pages (typical published text length).

Scope

The standard applies to knitted articles made from all types of yarns and threads and establishes methods for: determination of breaking characteristics for knitted articles (except hosiery and gloves), determination of extensibility under loads lower than breaking loads, measurement of residual deformations after loading, and determination of seam extensibility for pantyhose and similar products. It does not apply to certain small under‑foot items (for example, some types of under‑socks) as specified in the text.

Key topics and requirements

• Definitions and terminology related to knitted garments tensile testing.
• Requirements for specimen selection and preparation, including conditioning (temperature and humidity) before testing.
• Specified test methods for measuring breaking force and elongation; procedures for tests at loads lower than breaking load to determine extensibility and residual deformation.
• Procedures for seam extensibility testing (notably for pantyhose seams) and for excluding specific product types (e.g., certain hosiery and gloves) from some test methods.
• References to recommended test equipment (tensile testing machines, strip/grip methods or dedicated devices) and typical test parameters (sample geometry, gauge length, and test speed are defined in the standard text).

Typical use and users

Used by textile and garment manufacturers, laboratory testing and quality control departments, certification and conformity assessment bodies, material and product R&D teams, and procurement/inspection services that require standardized tensile and extensibility data for knitted articles.

Related standards

The standard refers to and is used alongside other textile and testing norms (examples include standards on sampling and specimen preparation such as GOST 9173-86 and other referenced normative documents used for conditioning, measurement units and test equipment). GOST 19712-89 replaced an earlier edition (GOST 19712-83) and was later issued with amendment(s).

FAQ

Q: What is this standard?

A: GOST 19712-89 is an interstate standard that specifies laboratory methods for determining breaking (tensile) characteristics and extensibility of knitted garments and knitted textile articles.

Q: What does it cover?

A: It covers specimen selection and conditioning, test procedures to measure breaking force and elongation, tests at sub‑breaking loads to determine extensibility and residual deformation, and seam extensibility tests for items such as pantyhose. It excludes certain hosiery and glove tests as noted in the standard text.

Q: Who typically uses it?

A: Textile and garment manufacturers, test laboratories, quality control engineers, certification bodies and R&D teams in the apparel and knitwear industry use this standard for consistent mechanical property assessment.

Q: Is it current or superseded?

A: As published sources indicate, GOST 19712-89 is maintained as an active (in‑force) standard; its period‑of‑validity restriction was removed by the relevant interstate body and it has received at least one amendment/reissue. Users should check national/regional registries for any later replacements or national adoptions before assuming applicability.

Q: Is it part of a series?

A: The document is part of the body of textile and clothing standards (GOST family) covering testing methods for textile materials and garments; it directly replaces the earlier GOST 19712-83 and references related testing and conditioning standards used in the textile sector.

Q: What are the key keywords?

A: knitted garments, tensile strength, elongation, extensibility, residual deformation, seam extensibility, textile testing, GOST 19712-89.
