Full title and description

GOST 9733.4-83 (ГОСТ 9733.4-83) — Textiles. Test method of colour fastness to washing. The standard specifies a laboratory procedure to determine the resistance of textile materials' colour to domestic and laboratory washing conditions (assessment of change in shade and staining on adjacent fabrics).

Abstract

This GOST defines a standardized test method for assessing the colour fastness of textile materials to washing, covering conditions from soft to hard (different water hardness and laundering aggressiveness), sample preparation, test cycle, evaluation by grey scale and staining assessment, and reporting requirements. It cross-references several ISO procedures for related checks and has at least one amendment recorded (Amd. 1-88).

General information

• Status: Catalog entries vary by source; many Russian standard libraries list the document as active, while some registries/catalogues indicate it has been superseded or its use limited in certain jurisdictions. Users should verify status with their national standards body before relying on it for compliance work.
• Publication date: Approved by the State Standards authority 17 February 1983; introduced into effect 1 January 1986 (document edition dates and reissues appear in some repositories).
• Publisher: Issued under the authority of the State Standards system (Gosstandart / interstate standards committee of the USSR); later maintained in Russian/Eurasian standard collections.
• ICS / categories: 59.080.01 (Textiles in general).
• Edition / version: Designation GOST 9733.4-83 (original 1983); commercial repositories show reissues/updates (notably listings with an edition date 01.12.1991 and an amendment №1 dated 1988).
• Number of pages: 4 pages (concise test method specification).

Scope

The standard applies to textile materials and specifies a laboratory test that reproduces domestic and controlled washing conditions to evaluate: (1) change in the colour of the tested specimen after washing; and (2) staining (transfer of colour) onto specified adjacent fabrics. It covers variants from mild to hard washing conditions and references related ISO test procedures for particular checks and reference materials. Use is intended for quality control, research and normative documentation for textile producers, testing laboratories and regulatory authorities.

Key topics and requirements

• Definition of sample preparation and conditioning before washing.
• Specification of washing procedures (detergent, temperature, mechanical action, water hardness) covering a range from soft to hard conditions.
• Evaluation criteria for change in colour using grey-scale references and numerical scoring.
• Assessment of staining (crocking/transfer) onto standard adjacent fabrics and rating procedures.
• Requirements for reporting results, including test conditions, specimen identification and observed ratings; normative references to related ISO methods (ISO 105-C series) and GOST cross-references.

Typical use and users

Applied by textile manufacturers, independent textile testing laboratories, quality assurance departments, certification bodies and standards bodies when evaluating colour fastness of fabrics and garments to washing. It is used for internal QC, acceptance testing of incoming materials, and as a normative reference in product specifications and regulatory documents.

Related standards

Part of the GOST 9733 series of textile testing methods (other parts cover distilled water, perspiration, ironing, etc.). Normative and related international references include ISO 105-C01 through ISO 105-C05 and, in many modern contexts, EN/ISO methods such as ISO 105-C06 used for colour fastness to washing. Some national catalogues list equivalence or replacement links to later ISO-based standards.

FAQ

Q: What is this standard?

A: GOST 9733.4-83 is a Soviet/Russian standard that defines a laboratory method to measure the colour fastness of textile materials to washing (i.e., how much a fabric changes colour or transfers colour to other materials when laundered).

Q: What does it cover?

A: It covers specimen preparation, specified washing conditions (including detergents, temperatures and water hardness ranges), the procedure for washing, and evaluation criteria for change in shade and staining using grey-scale and staining rating procedures. Normative references to related ISO procedures are included.

Q: Who typically uses it?

A: Textile manufacturers, QA/QC laboratories, certification bodies, standards organizations and research laboratories concerned with textile performance and compliance.

Q: Is it current or superseded?

A: Catalog information varies: several Russian standard repositories list GOST 9733.4-83 as active, while some national registries or commercial databases note replacements or alignment with ISO/EN equivalents (for example ISO 105-C06 in modern practice). Before using it for regulatory compliance, check the current status with your national standards body or the official standards registry.

Q: Is it part of a series?

A: Yes — it is one part of the GOST 9733 series of methods for testing colour fastness of textiles (other parts address distilled water, perspiration, ironing, etc.).

Q: What are the key keywords?

A: Colour fastness, washing, textile testing, grey-scale, staining, ISO 105, GOST 9733.4-83.
