Full title and description

ISO 105-C05:1989 — Textiles — Tests for colour fastness — Part C05: Colour fastness to washing: Test 5. This international standard specifies Test No. 5 of a series of washing tests for assessing the effect of washing on the colour fastness of dyed textiles; the procedure involves mechanical agitation of a specimen in a soap solution in contact with specified adjacent fabrics, followed by rinsing, drying and assessment with grey scales.

Abstract

This part of ISO 105 describes a single defined washing test (Test 5) within a set of five washing procedures intended to cover a range from mild to severe washing actions. The method determines change in colour of the test specimen and staining of adjacent fabrics after mechanical agitation in a soap solution; results are rated using grey scales. The procedure is intended to determine the effect of washing on colour fastness only, not to replicate an entire laundering process.

Scope

ISO 105-C05:1989 defines Test No. 5 in a series of five standardised washing tests used to evaluate the colour fastness of dyed textile materials to washing. The test specifies specimen preparation, the use of one or two specified adjacent fabrics in contact with the specimen, defined mechanical agitation, time and temperature in a soap solution, followed by rinsing, drying and assessment of colour change and staining with grey scales. The method is intended solely to determine the effect of washing on dye fastness and not to represent the full laundering process.

Key topics and requirements

• Definition of Test No. 5 within the ISO 105-C series — a specified washing procedure with mechanical agitation.
• Use of specified adjacent fabrics placed in contact with the test specimen to assess staining.
• Controlled conditions: soap solution, defined temperature and time, mechanical action, rinsing and drying.
• Assessment criteria: change in specimen colour and staining of adjacent fabrics judged with grey scales.
• Limitation: method determines only the effect of washing on colour fastness and is not intended to reproduce an entire laundering cycle.

Typical use and users

Laboratories performing textile testing, dye manufacturers, fabric and garment manufacturers, quality control and compliance teams, certification bodies and research institutions use this standard to evaluate and document the resistance of dyed textiles to washing under a defined laboratory procedure. As the 1989 edition has been withdrawn and integrated into later work, practitioners now typically refer to the superseding methods when establishing current test programs.

Related standards

ISO 105-C05:1989 is part of the ISO 105 series (colour fastness tests). It has been withdrawn and its content incorporated into later revisions of part C (notably ISO 105-C10:2006, which consolidates washing procedures). Regional/adopted equivalents (historically) include EN/UNE versions such as EN 20105-C05 (identical adoptions of the ISO text).

FAQ

Q: What is this standard?

A: ISO 105-C05:1989 is an international test method titled "Textiles — Tests for colour fastness — Part C05: Colour fastness to washing: Test 5" that defines a laboratory washing test to assess dye fastness of textiles.

Q: What does it cover?

A: It specifies specimen preparation, use of adjacent fabrics, mechanical agitation in a soap solution under defined time and temperature, rinsing and drying, and assessment of colour change and staining using grey scales; it is intended to measure the effect of washing on colour fastness only.

Q: Who typically uses it?

A: Textile testing laboratories, manufacturers of fibres, dyes, fabrics and garments, quality control teams, and research organizations historically used this test; today users typically apply the current or consolidated ISO C-part methods that supersede the 1989 text.

Q: Is it current or superseded?

A: ISO 105-C05:1989 has been withdrawn and superseded by later consolidated methods (notably ISO 105-C10:2006 and related revisions). The 1989 edition is not the current method for new testing programs.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 105 series on tests for colour fastness (the C‑series covers washing and laundering tests).

Q: What are the key keywords?

A: Colour fastness, washing test, ISO 105, Test 5, grey scale, textile testing, dye fastness, mechanical agitation, soap solution, withdrawn/superseded.
