Full title and description

Textiles — Tests for colour fastness — Part C04: Colour fastness to washing: Test 4. This part of ISO 105 specifies Test No. 4 of a series of washing tests in which a specimen, in contact with one or two specified adjacent fabrics, is mechanically agitated in a defined soap solution, then rinsed and dried; the change in the specimen's colour and the staining of adjacent fabrics are assessed using grey scales.

Abstract

ISO 105‑C04:1989 describes a standardized laboratory method to determine colour fastness to washing (Test 4) for textile materials. The procedure defines specimen preparation, the use of specified adjacent fabrics, agitation, time and temperature conditions in a soap solution, followed by rinsing and drying, with evaluation of colour change and staining by grey scales. The document has been recorded as withdrawn and later incorporated into updated washing methods in the ISO 105‑C series.

Scope

ISO 105‑C04:1989 defines Test 4 within the ISO 105‑C group of washing tests: it is intended to determine the resistance of a textile’s colour to a specified laboratory washing procedure and to measure the degree of staining of adjacent fabrics. The method is focused specifically on the colour change and staining outcomes (not on full laundering performance), and is one part of the broader ISO 105 series of colour‑fastness test methods. The test was later withdrawn and its approaches were folded into later consolidated washing methods in the ISO 105‑C family.

Key topics and requirements

• Specification of specimen and specified adjacent fabrics for simultaneous testing.
• Use of a defined soap solution and controlled mechanical agitation, temperature and time parameters.
• Rinsing and drying procedures standardized for consistent evaluation.
• Assessment criteria using grey scale(s) for change in colour of the specimen and staining of adjacent fabrics.
• Placement within the ISO 105 series as one of several washing severity tests (subsequently harmonized into later parts such as ISO 105‑C10).

Typical use and users

Laboratories, textile manufacturers, quality control departments, test houses and standards bodies historically used ISO 105‑C04 to assess and certify washing-related colour fastness properties of dyed and printed textile materials. After withdrawal, laboratories moved to the updated ISO 105‑C parts (e.g., C10) that consolidate and extend washing test methods.

Related standards

ISO 105‑C04 is part of the ISO 105 series (Textiles — Tests for colour fastness). It was withdrawn and its scope and test concepts were incorporated into later parts of the C subgroup such as ISO 105‑C10 (2006), which now provides consolidated washing test methods. National/adopted versions and regional equivalents (for example EN/DIN variants) also existed historically.

FAQ

Q: What is this standard?

A: ISO 105‑C04:1989 is an ISO test method titled "Textiles — Tests for colour fastness — Part C04: Colour fastness to washing: Test 4", specifying a laboratory washing test to assess colour change and staining.

Q: What does it cover?

A: It covers the procedure for Test No. 4 in the ISO 105‑C washing test series: specimen contact with adjacent fabric(s), mechanical agitation in a soap solution under defined time/temperature conditions, rinsing, drying and evaluation of colour change and staining by grey scales.

Q: Who typically uses it?

A: Textile testing laboratories, manufacturers, quality and compliance teams, and standards organizations — historically for product development and quality assurance regarding washfastness and staining. After withdrawal, users employ the updated ISO 105‑C parts.

Q: Is it current or superseded?

A: ISO 105‑C04:1989 is withdrawn. Its methods were superseded by later parts of the ISO 105‑C series (notably consolidated into ISO 105‑C10 and related documents). Consult the current ISO 105‑C parts for in‑force washing test methods.

Q: Is it part of a series?

A: Yes — ISO 105‑C04 is one section of the ISO 105 series ("Textiles — Tests for colour fastness"), which contains many parts addressing different agents and test methods (washing, rubbing, light, perspiration, etc.).

Q: What are the key keywords?

A: Colour fastness, washing, ISO 105, grey scale, staining, adjacent fabric, textile testing.
