GOST 30157.1-95 PDF

Full title and description

GOST 30157.1-95 — Textile fabrics. Methods for determination of dimensional changes after wet treatments and chemical cleaning. Modes of treatments. Specifies recommended test regimes (soaking, washing, rinsing, dehydration/spinning, drying, pressing/ironing) and the procedural conditions used to measure linear dimensional changes of textile fabrics and knitted coupons following wet processing or dry-cleaning.

Abstract

This part of the GOST 30157 series defines detailed treatment modes and practical test regimes for assessing dimensional changes (shrinkage/elongation) of textile fabrics after standard wet treatments and chemical cleaning. It gives tables of treatment parameters (bath ratio, temperature, detergents, durations, drying and ironing conditions), requirements for number and mass of specimens, and exclusions for special-structure fabrics. The document is aligned with ISO test practices referenced in the standard.

General information

• Status: Withdrawn / superseded on the territory of the Russian Federation (application ceased 01 August 2024); previously adopted as an interstate standard (GOST 30157.1-95).
• Publication date: Registered 1995 (document designation "-95"); published by IPK Publishing of Standards, Moscow (2001); date of introduction as RF national standard: 1 January 2002.
• Publisher: Interstate standard (GOST); published in printed/electronic form by IPK (Standards Publishing), Moscow.
• ICS / categories: ICS 59.080.30 (Textiles — test methods); Group M09.
• Edition / version: GOST 30157.1-95 (original 1995 interstate edition; entered into force in national practice 2002).
• Number of pages: 16 pages (typical published edition).

Scope

The standard applies to textile fabrics (including knitted coupons) and establishes test regimes for determining changes in linear dimensions after wet treatments or chemical cleaning. It does not apply to certain specialty constructions (for example, pleated or permanently crimped fabrics, some textured-elastic yarn fabrics, and a number of technical/special-purpose textiles — with limited exceptions such as linen and semi-linen). The chemical-cleaning procedure excludes knitted coupons. The part provides mode tables and procedural details referenced to the general provisions in GOST 30157.0-95.

Key topics and requirements

• Definition of treatment stages: soaking, washing, rinsing, dehydration (spin), drying and pressing/ironing.
• Preset test regimes (tables of modes) with specific parameters — bath ratio, water temperature, detergent type and concentration, time of treatment, agitation/turning instructions.
• Requirements for specimen preparation: number of elementary specimens, specimen mass tolerances and use of ballast if needed to reach required total mass.
• Detailed regimes for different fabric types (woven, knitted, pile/nap fabrics, knitted drying regimes by yarn type and areal density).
• Measurement procedure for linear dimensional change (pre- and post-treatment measurement and calculation of percent change).
• Normative references and alignment to relevant ISO standards for washing and soaking procedures (references include ISO 6330-type and ISO 7771-type practices as cited by the GOST text).
• Scope exclusions and special instructions for fabrics with pile, nap, or special finishes; handling rules to prevent distortion during wetting, drying and measurement.

Typical use and users

Used by textile manufacturers, quality-control and testing laboratories, material inspection bodies, apparel producers, research institutes and certification organizations to assess and document dimensional stability of textile fabrics after standard processing. Also used by product specification writers and technical designers to reference accepted test regimes for shrinkage and dimensional-change claims.

Related standards

Key related documents include GOST 30157.0-95 (general provisions for dimensional-change methods), national and international washing/cleaning test standards and machinery standards (examples cited in the GOST text: GOST 307.1-95, GOST 25652-83) and the ISO test methods referenced in the standard. On the territory where GOST 30157.1-95 was withdrawn it has been effectively replaced by modern ISO-based documents (for example the later GOST ISO 5077-2022 in the Russian system) and national adoptions derived from the GOST/ISO family.

FAQ

Q: What is this standard?

A: GOST 30157.1-95 is an interstate standard that defines modes of wet treatments and chemical-cleaning procedures used to determine linear dimensional changes of textile fabrics following processing.

Q: What does it cover?

A: It covers detailed treatment regimes (soak, wash, rinse, spin, dry, press), specimen preparation requirements, parameters for different fabric types and the procedural steps needed to measure and calculate dimensional change. It also lists exclusions for specific fabric structures.

Q: Who typically uses it?

A: Textile and apparel manufacturers, testing and QC laboratories, standards bodies, certification and inspection organizations, textile research institutes and technical specification authors.

Q: Is it current or superseded?

A: The document GOST 30157.1-95 itself has been withdrawn for use in the Russian Federation (application ceased 1 August 2024) and has been replaced in that system by ISO-aligned standards (for example GOST ISO 5077-2022 in the Russian standards catalogue). It remains a historical/interstate reference for older specifications but users should follow the currently mandated national or ISO-based test standards in their jurisdiction.

Q: Is it part of a series?

A: Yes — it is part of the GOST 30157 series; GOST 30157.0-95 provides general provisions and this document (30157.1-95) provides the modes/regimes. The series aligns with relevant ISO washing/soaking methodology.

Q: What are the key keywords?

A: Textile fabrics; dimensional change; shrinkage; wash regimes; chemical cleaning; test methods; specimen preparation; drying; ironing; GOST 30157.1-95.
