Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for
coloured textiles and colorants, in collaboration with the European Committee for Standardization (CEN)
Technical Committee CEN/TC 248, Textiles and textile products, in accordance with the Agreement on
technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 105-C12:2004), which has been technically
revised.
The main changes are as follows:
— ISO 105-F:1985 was withdrawn and the test conditions of industrial laundering are seldom used for the
fabrics mainly made of delicate fibres (for example silk or wool), therefore ISO 105-C12:2004/Cor 1:2007
has not been suitable to be incorporated into this method;
— addition of ISO 3696 and replacement of ISO 105-A01:1994 with ISO 105-A01 in Clause 2;
— revision of clause title from “Reagents” to “Reagents and materials” in Clause 5 (Former Clause 4);
— addition of “Other suitable detergent can be used if agreed upon between interested parties.” in 5.1
(former 4.1);
— clarification that 30 % is mass fraction in 5.3 (former 4.3);
— addition of sodium percarbonate as an optional reagent in 5.6, 8.1.3, Table 1 and A.1 (former 4.6, 7.1.3,
Table 1 and A.1);
— replacement of “see 8.2 of ISO 105-A01:1994” with “in accordance with ISO 3696” in 5.7 (former 4.7);
— movement of “Adjacent fabrics” and “Grey scales” to the clause “Reagent and materials”;
— addition of the statement “using either a multifibre adjacent fabric or two single-fibre adjacent fabrics as
specified in ISO 105-A01.” in 5.8 (former 5.4);

ISO 105-C12:2024(en)
— deletion of “Condition the sample for 24 h before assessing to allow for temporary colour change caused
by heat.” in 6.6 (former 5.6);
— addition of “Balance, with a resolution of 0,01 g.” in Clause 6 (former Clause 5);
— add
