Full title and description

ISO 105‑E03:2010 — Textiles — Tests for colour fastness — Part E03: Colour fastness to chlorinated water (swimming‑pool water). Specifies laboratory test methods to determine the resistance of textile colours to active chlorine concentrations such as those used to disinfect swimming‑pool water.

Abstract

ISO 105‑E03:2010 defines a simple, repeatable procedure for exposing textile specimens to active chlorine (sodium hypochlorite) at specified concentrations and times, then assessing change in colour by grey scale or instrumental measurement. Three alternative test conditions are given (including concentrations intended for swimwear and for accessories), and the standard includes requirements for specimen preparation, test temperature, exposure time and reporting.

Scope

This part of ISO 105 specifies a laboratory method for determining the resistance of the colour of textiles (all fibres and constructions) to the action of active chlorine at concentrations representative of swimming‑pool disinfection (break‑point chlorination). The scope covers specimen conditioning, test solutions and concentrations, exposure procedure, drying, and assessment of colour change.

Key topics and requirements

• Definition of three alternative test conditions with specified active‑chlorine concentrations (typical values include 20 mg/L, 50 mg/L and 100 mg/L for different end‑uses such as towels, accessories and swimwear).
• Preparation and mounting of specimens and specified liquor ratio, temperature control (around 27 ± 2 °C for typical procedures) and exposure time.
• Post‑exposure handling (squeezing or hydroextracting, air drying in subdued light) before assessment.
• Assessment of change in colour using the grey scale and/or instrumental measurement with reporting of numerical ratings and test conditions.
• Requirements for test-report content (identification of sample, chlorine concentration used, any deviations, and numerical results).

Typical use and users

Used by textile testing laboratories, quality control departments of textile and swimwear manufacturers, material specification engineers, and certification bodies to evaluate product resistance to swimming‑pool chlorine and to support product claims and specifications (e.g., suitable for swimwear, beach towels, poolside accessories). Test houses offering textile fastness testing commonly apply this method.

FAQ

Q: What is this standard?

A: ISO 105‑E03:2010 is an international standard that specifies a laboratory method to evaluate the resistance of textile colours to active chlorine concentrations used in swimming‑pool disinfection.

Q: What does it cover?

A: It covers specimen preparation, specified chlorine concentrations and exposure conditions, post‑exposure handling, and assessment of colour change (grey scale or instrumental), plus reporting requirements. Three alternative test conditions are provided for different product types.

Q: Who typically uses it?

A: Textile testing laboratories, manufacturers (especially swimwear and pool‑accessory producers), product developers, quality assurance teams and conformity/certification bodies use this standard to assess and document chlorine colour fastness.

Q: Is it current or superseded?

A: The 2010 edition (Edition 4) is the current published edition; ISO records show it was published in April 2010 and was last reviewed and confirmed in 2020, remaining the active edition.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 105 series (Textiles — Tests for colour fastness), which contains many parts addressing different agents and assessment methods.
