Full title and description

ISO 105‑C10:2006 — Textiles — Tests for colour fastness — Part C10: Colour fastness to washing with soap or soap and soda. This part of ISO 105 specifies standardized laboratory methods (five wash procedures) for determining the effect of washing with soap, or soap and soda, on the colour fastness of textile materials and on adjacent fabrics.

Abstract

ISO 105‑C10:2006 defines five methods intended to determine the resistance of textile colour to washing procedures ranging from mild to severe (domestic and commercial type washes). The methods are designed to measure the effect of washing on colour fastness only and are not intended to represent the result of a comprehensive laundering procedure.

Scope

ISO 105‑C10:2006 specifies five laboratory wash procedures (usually designated A–E) that simulate a range of domestic and commercial laundering conditions from mild to severe. Methods cover test liquor composition, temperature/time profiles, mechanical action, specimen preparation in contact with adjacent fabrics (to assess staining), rinsing, drying and evaluation of colour change and staining. The standard is intended solely to assess the effect of washing on colour fastness, not to represent a full household laundering performance.

Key topics and requirements

• Five defined wash procedures (A–E) covering different temperatures and severities to simulate a spectrum of wash conditions.
• Test liquor compositions: typical soap solution for routine tests (example values given in the standard) and soap + sodium carbonate for harsher conditions (the EN/ISO adoption specifies typical reagent levels such as 5 g soap per litre and 2 g Na2CO3 per litre in the reference wash liquor).
• Specimen preparation and adjacent-fabric assessment (multifibre or specified adjacent fabrics) to evaluate staining and transfer.
• Apparatus and mechanical action requirements (rotating water‑bath laundering device, specified containers/balls, controlled temperature and rotation) and a recommended liquor ratio (commonly 50:1 ml/g).
• Post-wash rinsing, drying and visual/instrumental evaluation using ISO grey scales and referenced ISO methods for reporting results.

Typical use and users

Used by textile manufacturers, converters, independent test laboratories, certification bodies, brands and retailers for product development, quality control and claims verification where wash colour fastness or staining of adjacent fibres must be assessed. R&D teams and dye/finish formulators use the methods to optimise dyeing and finishing for wash performance.

Related standards

ISO 105‑C10 is part of the ISO 105 series (Tests for colour fastness). Related documents include ISO 105‑A01 (general principles), ISO 105‑A02/A03 (grey scales for change of colour and staining), ISO 105‑F (adjacent fabrics / multifibre), ISO 105‑J01 (instrumental assessment) and other ISO 105 parts for laundering with different detergents/bleaches (e.g., C06, C08, C09). The ISO text consolidated and replaced earlier ISO 105‑C0x sections (C01–C05).

FAQ

Q: What is this standard?

A: ISO 105‑C10:2006 is an international standard that specifies laboratory methods for assessing colour fastness of textiles to washing with soap or with soap and soda.

Q: What does it cover?

A: It covers five defined wash procedures (from mild to severe), test liquor compositions and concentrations for soap-based washes, apparatus and mechanical action, specimen and adjacent-fabric preparation, evaluation (visual and instrumental) and reporting requirements. It is intended to measure the effect of washing on colour fastness only.

Q: Who typically uses it?

A: Textile manufacturers, converters, independent testing laboratories, certification bodies, brands and retailers, and R&D teams working on dyes and finishes.

Q: Is it current or superseded?

A: ISO 105‑C10:2006 is published and—according to ISO lifecycle records—was confirmed in periodic reviews (the ISO entry indicates the publication is current and was last reviewed/confirmed in 2025). Regional adoptions (for example EN ISO 105‑C10:2007) exist; those adoption documents may show different publication/endorsement dates or additional front matter but do not alter the technical content of the ISO edition.

Q: Is it part of a series?

A: Yes — it is part of the ISO 105 series (Tests for colour fastness). ISO 105‑C10 consolidates and replaces several earlier C‑section documents (ISO 105‑C01 to C05) and is related to other C‑parts (C06, C08, C09) and ISO 105 general/auxiliary parts (A, F, J series).

Q: What are the key keywords?

A: Colour fastness, wash fastness, soap, soap and soda, ISO 105, multifibre, adjacent fabric, textile testing, laundering test, grey scale.
