Full title and description

ISO 105-C12:2024 — Textiles — Tests for colour fastness — Part C12: Colour fastness to industrial laundering. This International Standard specifies methods for determining the resistance of the colour of textiles of all kinds when exposed to industrial laundering procedures.

Abstract

This part of ISO 105 defines laboratory methods to assess colour change and cross‑staining of textile materials subjected to industrial laundering processes. The procedures are intended to reproduce the chemical and mechanical actions encountered during industrial wash cycles and to provide reproducible comparative results for quality control, specification and conformity testing.

Scope

Specifies methods for determining the resistance of colour of all types of textile materials to industrial laundering procedures. Tests cover assessment of colour change of the specimen and staining of adjacent fabrics caused by chemical and mechanical actions during industrial washing. The standard is intended for use in quality control, comparative testing and contract verification.

Key topics and requirements

• Defined test procedures to simulate industrial laundering (chemical agents, mechanical action and temperatures) and to measure colour change and staining.
• Use of controlled test cycles intended to approximate effects produced by multiple industrial launderings — one laboratory “cycle” is intended to represent the colour loss/cross‑staining resulting from several (typically multiple) industrial washes.
• Assessment criteria based on grey scales or established rating systems for colour change and staining to adjacent fabrics.
• Applicability to all textile forms (woven, knitted, non‑woven, finished and unfinished materials) unless otherwise stated.
• Normative references and relationships to other ISO 105 series parts (general principles, domestic washing, etc.) for consistent interpretation and reporting.

Typical use and users

Used by textile manufacturers, industrial laundries, independent testing laboratories, quality managers, product specification authors and procurement teams to verify colour fastness performance under industrial laundering conditions. Standards committees and conformity assessment bodies also use it when harmonizing test methods or drafting technical regulations.

Related standards

ISO 105 is a multipart series; closely related parts include ISO 105-A01 (general principles of testing) and ISO 105-C06 (colour fastness to domestic and commercial laundering), among other C, E and D parts that cover different agents (domestic washing, dry cleaning, water, perspiration, etc.). ISO 105-C12:2024 replaces the 2004 edition of C12.

FAQ

Q: What is this standard?

A: ISO 105-C12:2024 is an International Standard that specifies laboratory test methods to evaluate how textile colours withstand industrial laundering processes (wash fastness and staining).

Q: What does it cover?

A: It covers procedures to reproduce industrial wash conditions (chemical and mechanical actions), describes specimen preparation, test cycles and assessment criteria for colour change and cross‑staining. The tests are intended for comparative and quality control use.

Q: Who typically uses it?

A: Textile and garment manufacturers, industrial laundries, test laboratories, purchasers, compliance and quality teams, and standards committees.

Q: Is it current or superseded?

A: Current — ISO 105-C12:2024 (Edition 2) was published 12 February 2024 and replaces ISO 105-C12:2004 (and its corrigenda).

Q: Is it part of a series?

A: Yes — it is one part of the multipart ISO 105 series (Tests for colour fastness). Relevant companion parts include ISO 105-A01 (general principles), ISO 105-C06 (domestic/commercial laundering) and many other A, B, C, D, E, J parts addressing specific agents and procedures.

Q: What are the key keywords?

A: Colour fastness, industrial laundering, textile testing, wash fastness, ISO 105, cross‑staining, quality control.
