Full title and description

GOST 30157.0-95 — Textile fabrics. Methods of measures changes determination after wet treatments and chemical cleaning. General. (Russian: ГОСТ 30157.0-95 — Полотна текстильные. Методы определения изменения размеров после мокрых обработок или химической чистки. Общие положения.)

Abstract

This standard establishes general provisions for laboratory methods used to determine dimensional changes (shrinkage or growth) of textile fabrics — including woven and knitted fabrics — after specified wet treatments (washing, soaking, boiling, finishing washes) and after chemical (dry) cleaning. It defines specimen preparation, marking and measuring, treatment regimes, calculation of percentage change in warp and weft (length and width), reporting requirements and necessary apparatus and reagents.

General information

• Status: National / interstate GOST standard (original designation 30157.0-95). Adopted in the 1990s and introduced into force on 1 January 2002; some registries list the document as replaced or withdrawn in part—users should confirm current national status before relying on it for regulatory compliance.
• Publication date: Designation year 1995 (suffix “-95”); date of official introduction into force: 01 January 2002.
• Publisher: Issued as an interstate / GOST document (adopted by the Interstate Council for Standardization, Metrology and Certification); printed/distributed editions commonly show IPK — Publishing House of Standards / national standards bodies as the publisher.
• ICS / categories: Textiles — general / test methods. Common ICS classification shown: 59.080.30 (textile fabrics) / related classifications for textiles in general.
• Edition / version: GOST 30157.0-95 (original 1995 designation; national introduction 2002). May have later amendments/corrections in national collections.
• Number of pages: Editions vary by publisher — catalog records show typical lengths in the range of about 8–12 pages depending on format/edition.

Scope

Applies to textile fabrics (including many types of woven and knitted textiles) and sets out general rules for determining dimensional change after wet processes (various washing, soaking and finishing regimes) and after chemical dry-cleaning. The standard is normative for sample selection, marking, conditioning, measurement before and after treatment, treatment parameters, calculation of percentage change along warp and weft and the form of test reports. It is intended for laboratory and production quality control and for establishing product specification requirements.

Key topics and requirements

• Definitions and terminology for dimensional change (shrinkage/elongation) in warp and weft directions.
• Specification of specimen size, number of elementary specimens and marking method prior to treatment.
• Detailed treatment regimes: prescribed washing, soaking, machine cycles, drying and chemical cleaning procedures for different fabric groups (modes and durations are defined in companion parts such as GOST 30157.1-95).
• Required apparatus and materials (washing machines or baths, drying cabinets, irons, measuring equipment, solvents for dry-cleaning, detergents and auxiliaries).
• Measurement procedure: conditioning, pre- and post-treatment measuring points, calculation of percentage change in length and width, rounding and reporting conventions.
• Reporting: test results for warp and weft dimensional change, test conditions, date/place, personnel and any deviations from standard methods.
• Normative annexes or tables linking fabric types to recommended test regimes and specimen counts (illustrative sizes and minimum holding times for different fabric categories). (xn-----6kcbaeeywflm3c1andac1au8v.xn--p1ai)

Typical use and users

Used by textile manufacturers, fabric converters, quality control laboratories, test houses, garment producers, procurement/specification engineers and conformity assessment bodies to: verify dimensional stability claims, define care instructions, resolve disputes on shrinkage, and include dimensional-change requirements in technical specifications and contracts. Also used by standards committees when harmonizing test methods with international standards.

Related standards

Closely related documents include GOST 30157.1-95 (modes of treatments / specific regimes), ISO 5077 (Determination of dimensional change in washing and drying) and other regional/national methodologies for washing and dry-cleaning tests (for example ISO/EN washing and dimensional stability standards, national GOST variants and later ГОСТ ISO adoptions). Users often consult ISO 5077 when aligning GOST methods with international practice.

FAQ

Q: What is this standard?

A: GOST 30157.0-95 is an interstate (GOST) standard that provides general provisions and laboratory procedures for determining dimensional change of textile fabrics after wet treatments (washing, soaking, finishing washes) and after chemical (dry) cleaning.

Q: What does it cover?

A: It covers specimen selection and marking, conditioning, specified treatment regimes, measurement before and after treatment, calculation of percentage change in warp and weft, apparatus and reagents, and reporting requirements; specific treatment modes are detailed in companion parts (e.g., GOST 30157.1-95). (xn-----6kcbaeeywflm3c1andac1au8v.xn--p1ai)

Q: Who typically uses it?

A: Textile and garment manufacturers, testing laboratories, quality assurance teams, standards bodies and conformity assessment organizations use the standard for product specification, care-labelling decisions and quality disputes involving dimensional stability.

Q: Is it current or superseded?

A: The document was adopted with designation year 1995 and introduced into force on 1 January 2002. Some registries and later standardization actions have replaced or updated parts of the GOST 30157 series and related national parts (for example later national adoption of ISO methods). Because national standards status can change, verify current applicability in the relevant national registry or with the national standards body before using it for regulatory or contractual purposes.

Q: Is it part of a series?

A: Yes — GOST 30157.0-95 is the “general” part of a series that includes companion parts (for example GOST 30157.1-95 covering specific treatment regimes). The series defines both general rules and the detailed modes required for particular fabric groups.

Q: What are the key keywords?

A: Textile fabrics; dimensional change; shrinkage; washing; dry cleaning; specimen marking; warp and weft; GOST 30157; test methods.
