Full title and description

ISO 105-C02:1989 — Textiles — Tests for colour fastness — Part C02: Colour fastness to washing: Test 2. This part of ISO 105 specifies Test No. 2 in a series of five standardized washing procedures used to assess the effect of washing on the colour fastness of textiles when a specimen is agitated in a soap solution in contact with one or two adjacent fabrics and then rinsed and dried.

Abstract

This standard defines a controlled laboratory method (Test No. 2 of five) for evaluating the change in colour of a textile specimen and the staining of specified adjacent fabrics after mechanical agitation in a soap solution under prescribed time and temperature conditions; assessment is made using grey scales for colour change and staining.

Scope

Specifies Test No. 2 of a set of five washing tests designed to cover a range of washing severities (from mild to severe). The method applies to determining the effect of washing only on the colour fastness of dyed or printed textiles: a specimen in contact with one or two specified adjacent fabrics is mechanically agitated in a soap solution at a prescribed temperature and time, then rinsed and dried; colour change and staining are evaluated with grey scales. The method is not intended to reproduce the entire laundering process (for example full bleaching operations).

Key topics and requirements

• Test No. 2 procedure within the ISO 105‑C series covering washing fastness.
• Specimen contact with one or two designated adjacent fabrics (multifibre/adjacent fabric specified by related parts).
• Mechanical agitation in a soap solution at prescribed temperature and duration (controlled bath temperature and agitation frequency).
• Post-wash rinsing and drying before assessment.
• Assessment using grey scales for change in colour and staining of adjacent fabric(s).
• Designed to measure the effect of washing on colour fastness only — not a full simulation of consumer laundering with all process variables.

Typical use and users

Used by textile test laboratories, manufacturers (dye houses, fabric mills), quality assurance teams, research and development groups, and conformity assessment bodies for routine colour fastness evaluation and product specification. Laboratories employ this method to ensure dyeing processes and finishing treatments meet required wash‑fastness performance before market release.

Related standards

Part of the ISO 105 series (colour fastness tests). ISO 105-C02:1989 has been withdrawn and its wash‑fastness methods were later consolidated/revised in subsequent publications (for example ISO 105‑C10:2006 which revises several earlier C01–C05/C02 methods). Users are directed to consult the later ISO 105-C series documents for current procedures.

FAQ

Q: What is this standard?

A: ISO 105‑C02:1989 is an International Organization for Standardization method titled "Textiles — Tests for colour fastness — Part C02: Colour fastness to washing: Test 2", describing a specific laboratory washing test procedure for assessing wash‑fastness.

Q: What does it cover?

A: It covers Test No. 2 of a series of five standardized washing tests: specimen contact with specified adjacent fabrics, mechanical agitation in a soap solution under controlled time and temperature, rinsing, drying and evaluation 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 manufacturers, dye houses, independent testing laboratories, QA/QC personnel, and R&D groups use this method to evaluate and specify wash fastness performance. Accredited test labs perform these standardized tests for suppliers and retailers.

Q: Is it current or superseded?

A: ISO 105‑C02:1989 is withdrawn (the edition issued December 1989 is no longer current). Its wash‑fastness procedures have been revised and consolidated in later ISO documents — notably ISO 105‑C10:2006 which replaces several earlier C‑part methods. Some repository records also note administrative withdrawal actions in later years. Users should use the current ISO 105 series parts when available.

Q: Is it part of a series?

A: Yes — ISO 105 is a comprehensive series of standards on tests for colour fastness; Part C02 is one part of the C (washing) subgroup within the ISO 105 family. Other related parts define adjacent fabrics, different wash severities and other exposures (e.g., C01–C05 historically, and later consolidated updates).

Q: What are the key keywords?

A: Colour fastness, wash fastness, ISO 105, textile testing, grey scale, adjacent fabric, soap wash test, mechanical agitation.
