Full title and description

ISO 105-C01:1989 — Textiles — Tests for colour fastness — Part C01: Colour fastness to washing: Test 1. This International Standard specifies Test No. 1 of a series of washing tests for assessing the effect of washing on the colour fastness of textiles using specified adjacent fabrics, mechanical agitation in a soap solution, rinsing and drying, with assessment by grey scales.

Abstract

This part of ISO 105 defines a controlled laboratory method (Test 1) to determine change in colour of a textile specimen and staining of adjacent fabric(s) after a specified washing procedure (time, temperature and mechanical action) in a soap solution; results are evaluated with grey scales. The method is intended to determine the effect of washing on dye fastness, not to reproduce a full laundering process.

Key bibliographic and lifecycle details above are recorded on ISO's bibliographic entry for ISO 105-C01:1989; the part has been withdrawn and the C‑series washing methods were consolidated into later documents (see Related standards).

Scope

Specifies Test No. 1 of a series of five washing tests intended to investigate colour fastness to washing for dyed textiles over a range of procedures from mild to severe. The test covers specimen preparation, choice of adjacent fabric(s), apparatus and reagents (soap solution), defined time and temperature, mechanical agitation, rinsing and drying, and assessment of both change in the specimen and staining of adjacent fabrics using grey scales. It is intended to determine the effect of washing on colour fastness only, not to reproduce complete household laundering processes.

Key topics and requirements

• Definition of Test No. 1 conditions (time, temperature, mechanical action) within the ISO 105-C sequence.
• Use of one or two specified adjacent fabrics placed in contact with the specimen during washing to evaluate staining.
• Preparation of a standard soap detergent solution and specified liquor-to-goods ratio.
• Mechanical agitation in a suitable device (rotatable bath or equivalent) followed by rinsing and drying.
• Assessment procedures: grey scale for change in colour (specimen) and grey scale for staining (adjacent fabric).
• Normative references to other ISO 105 parts for adjacent fabrics and grey scales where applicable.

These requirements are summarized from the ISO bibliographic and method description for the C01 test.

Typical use and users

Used historically by textile test laboratories, quality assurance departments in textile and apparel manufacturing, dye and chemical suppliers, research institutes and standards bodies to assess and compare the washing fastness of dyed textiles. After withdrawal, users migrated to the consolidated ISO 105-C10 (and related C-series parts) methods for routine testing.

Related standards

ISO 105-C01:1989 is part of the ISO 105 series (Tests for colour fastness). The C01 method has been superseded/consolidated into later C-series standards — notably ISO 105-C10:2006 (which provides a consolidated set of washing test methods) — and references other ISO 105 parts such as general principles and adjacent-fabric specifications. Consult the ISO 105 family for companion methods (C02–C05/C10) and A‑parts for general principles.

FAQ

Q: What is this standard?

A: ISO 105-C01:1989 is an ISO test method titled "Textiles — Tests for colour fastness — Part C01: Colour fastness to washing: Test 1" that specified one of a series of laboratory washing tests for assessing colour change and staining.

Q: What does it cover?

A: It covers specimen and adjacent-fabric arrangement, apparatus and reagents (soap solution), defined time/temperature/mechanical action for Test 1, post-wash rinsing and drying, and assessment of colour change and staining using grey scales — intended to measure washing effect on dye fastness, not full laundering performance.

Q: Who typically uses it?

A: Textile test laboratories, manufacturers and QA teams, dye and chemical suppliers, research organizations and standards committees. After withdrawal, these users typically refer to the consolidated C‑series standards such as ISO 105-C10:2006.

Q: Is it current or superseded?

A: ISO 105-C01:1989 has been withdrawn and the washing methods were consolidated; ISO 105-C10:2006 is the later consolidated reference for C‑series washing tests that replaces earlier individual C0x parts. Users should use the current ISO 105 family documents for normative testing.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 105 series (Tests for colour fastness). The C-section contains multiple washing-related parts (C01–C05 historically) that together address different washing severities and procedures; these were later consolidated into documents such as ISO 105-C10.

Q: What are the key keywords?

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