GOST 9733.6-83 PDF

Full title and description

GOST 9733.6-83 — "Textile materials. Test methods of colour fastness to perspiration" — establishes laboratory procedures for determining the resistance of textile colourings to the action of human perspiration (artificial sweat) and the assessment of resulting colour change and staining of adjacent fabrics.

Abstract

This standard specifies a controlled immersion/exposure test using acidic and alkaline artificial perspiration solutions to evaluate colour fastness of dyed textile materials. Results are assessed by comparison with grey scales for change in colour and for staining of adjacent undyed fabrics; the method is equivalent in principle to ISO 105‑E04 test procedures.

General information

• Status: Active (original GOST in force; noted as being replaced by GOST ISO 105‑E04‑2023 with transition provisions in national registries).
• Publication date: Approved 17 February 1983; commonly listed as in force from 1 January 1986 (designation GOST 9733.6‑83).
• Publisher: Gosstandart (State Standards Committee of the USSR) / Interstate Standard.
• ICS / categories: 59.080.01 — Textiles; colour fastness test methods.
• Edition / version: Original issue: GOST 9733.6‑83 (1983/1986).
• Number of pages: 4 pages (short test-method specification).

Scope

The standard applies to dyed textile materials and sets out laboratory conditions, test specimen preparation, composition of artificial sweat solutions (acidic and alkaline), exposure time and temperature, rinsing and drying procedures, and the methods for visual assessment of both change in colour of the specimen and staining of adjacent undyed fabrics. It is intended for quality-control testing and comparative evaluation of colour fastness to perspiration.

Key topics and requirements

• Definition of test specimens and conditioning before testing (sample size, mounting, contact fabrics).
• Preparation and composition of acidic and alkaline artificial perspiration solutions and their use in tests.
• Specified exposure parameters: temperature, time and mechanical conditions (immersion/pressure) for reproducible results.
• Use of standard grey scales to assess change in colour and staining; reporting of numerical grades.
• Requirements for test equipment and accessories (perspirometer / immersion apparatus; adjacent undyed fabrics; rinsing and drying procedures).

Typical use and users

Applied by textile test laboratories, manufacturers of dyed fabrics and garments, quality assurance and compliance departments, research institutes, and certification bodies for evaluating and documenting colour fastness performance to perspiration. Useful in production quality control, comparative testing of dyes/finishes, and conformance checks for consumer textiles.

Related standards

Part of the GOST 9733 series of colour‑fastness test methods (examples: GOST 9733.4‑83 — colour fastness to washing; GOST 9733.5‑83 — to distilled water; GOST 9733.9‑83 — to seawater). The method corresponds to and has been superseded in many jurisdictions by ISO 105‑E04 and national adoption as GOST ISO 105‑E04‑2023.

FAQ

Q: What is this standard?

A: GOST 9733.6‑83 is a Soviet/Interstate standard that defines laboratory procedures to evaluate the resistance of textile dyes to human perspiration (artificial sweat).

Q: What does it cover?

A: It covers specimen preparation, composition of acidic and alkaline perspiration solutions, test exposure conditions (time, temperature, contact), assessment of colour change and staining using grey scales, and reporting of results.

Q: Who typically uses it?

A: Textile manufacturers, laboratory technicians, quality control and certification bodies, and research organizations concerned with dye performance and consumer safety of textile products.

Q: Is it current or superseded?

A: Historically in force as GOST 9733.6‑83; in recent national updates it has been mapped to and replaced by GOST ISO 105‑E04‑2023 in some registries — users should verify the applicable national/regional transition dates (for example, registries note cessation/replacement dates in national application).

Q: Is it part of a series?

A: Yes — it is one part of the GOST 9733 series of textile colour‑fastness test methods (multiple parts for washing, water, perspiration, seawater, etc.), and is conceptually aligned with the ISO 105 series (colour fastness tests).

Q: What are the key keywords?

A: Colour fastness, perspiration (artificial sweat), staining, grey scale, textile test, GOST 9733.6‑83, ISO 105‑E04.
