ISO 105‑C09:2001 cor1:2002 — Textiles — Tests for colour fastness — Part C09: Colour fastness to domestic and commercial laundering — Oxidative bleach response using a non‑phosphate reference detergent incorporating a low temperature bleach activator. This entry refers to the original 2001 International Standard (Edition 1) and its Technical Corrigendum 1 published in 2002 (corrigendum later withdrawn as a separate document). The method assesses consumer‑relevant shade change caused by oxidative (oxygen) bleaching in domestic and commercial laundering formulations that use a low‑temperature bleach activator.

Abstract

This part of ISO 105 specifies a laboratory method to determine the shade‑change behaviour of textiles (all types except silk and wool) when exposed to domestic and commercial laundering procedures that include an oxygen bleaching system activated at low temperature. The test uses a non‑phosphate reference detergent together with a peroxygen bleaching agent and a bleach activator to simulate consumer/commercial wash conditions. The method indicates probable shade change after repeated launderings; it is not intended for assessment of dye staining of adjacent fabrics and does not account for optical brightener effects.

General information

• Status: Published (ISO 105‑C09:2001, Edition 1). Technical Corrigendum ISO 105‑C09:2001/Cor 1:2002 was published in 2002 and is recorded as a corrigendum to the 2001 edition (corrigendum itself later withdrawn as a standalone stage item); Amendment ISO 105‑C09:2001/Amd 1:2003 also applies to the 2001 edition.
• Publication date: Main standard: 20 December 2001. Corrigendum (Cor 1): May 2002. (Amendment 1: 2003)
• Publisher: International Organization for Standardization (ISO)
• ICS / categories: 59.080.01 — Textiles in general (Colour fastness tests)
• Edition / version: Edition 1 (2001) with Technical Corrigendum 1 (2002) and Amendment 1 (2003)
• Number of pages: Main document: 6 pages. Corrigendum: 1 page. (Amendment: short amendment document, typically a few pages)

Scope

The standard specifies a reproducible test procedure for assessing shade change of textile specimens subjected to domestic and commercial laundering cycles that include an oxidative (oxygen) bleaching system activated at low temperature. It covers selection and preparation of test specimens, the non‑phosphate reference detergent formulation, bleaching agent and activator (as used in the test), wash conditions, evaluation of shade change (typically by visual comparison to a grey scale), and reporting. The procedure excludes silk and wool and is not intended for assessing staining of adjacent fabrics or the separate influence of optical brighteners present in some commercial detergents.

Key topics and requirements

• Purpose: measure consumer‑relevant shade change from oxygen bleaching in laundering.
• Test specimen types and conditioning (exclusions: silk and wool).
• Reference detergent: use of a non‑phosphate ECE/AATCC style reference detergent formulation.
• Bleaching system: specified peroxygen bleaching agent (e.g., sodium perborate) and a low‑temperature bleach activator (e.g., TAED) at defined concentrations.
• Wash procedure: defined washer type or laboratory simulation, temperature, liquor ratio, and number of cycles to represent multiple launderings.
• Evaluation: visual assessment of shade change using a grey scale or equivalent assessment method; procedures for replicates and reporting.
• Limitations: not for dye staining evaluation of adjacent fabrics; optical brightener effects not covered by this method.

Typical use and users

Used by textile testing laboratories, quality control departments in textile and apparel manufacturing, research and development groups evaluating dye/finish fastness, independent conformity assessment bodies, and standards committees. The method supports product development, quality assurance, comparative testing of detergents/bleaches, and compliance testing where oxidative bleaching performance is relevant.

Related standards

This part is one member of the ISO 105 series (Textiles — Tests for colour fastness). Related parts and documents commonly used alongside C09 include general methods and trait‑specific parts (for example ISO 105‑A series for general principles and ISO 105‑A04 for assessment of staining). Other C‑parts cover different laundering and bleaching conditions or alternative wash systems. National test methods and supplementary documents (AATCC procedures, regional reference detergents) may also be referenced when comparing or translating results.

FAQ

Q: What is this standard?

A: ISO 105‑C09:2001 is an international test method for assessing the shade change of textiles caused by domestic or commercial laundering that includes an oxidative (oxygen) bleaching system activated at low temperature. The entry here also references the Technical Corrigendum 1 issued in 2002 and the Amendment issued in 2003.

Q: What does it cover?

A: It covers specimen preparation, the specified non‑phosphate reference detergent and bleaching chemicals, wash conditions, evaluation of shade change, and reporting requirements. It excludes silk and wool and does not assess dye staining of adjacent fabrics or the separate contribution of optical brighteners.

Q: Who typically uses it?

A: Textile manufacturers, laboratory analysts, quality assurance teams, independent test houses, and researchers use the method to evaluate and compare textile resistance to colour change from oxidative bleaching in laundering.

Q: Is it current or superseded?

A: The original edition was published in December 2001 (Edition 1). A Technical Corrigendum (Cor 1) was issued in 2002 and recorded against the 2001 edition (the corrigendum document is a short correction notice); an Amendment (Amd 1) was published in 2003. Users should check the official ISO catalogue or their national standards body for the current legal/published status and any subsequent revisions or replacements before relying on the procedure for compliance decisions.

Q: Is it part of a series?

A: Yes. ISO 105‑C09 is part of the ISO 105 series: "Textiles — Tests for colour fastness," a multi‑part family of standards addressing various aspects of colour fastness to light, washing, rubbing, perspiration, and other conditions. Many other ISO 105 parts and national equivalents provide complementary methods.

Q: What are the key keywords?

A: Colour fastness, laundering, oxidative bleach, bleach activator, non‑phosphate detergent, textile testing, ISO 105, shade change, TAED, sodium perborate.
