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 documents 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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent
rights identified during the development of the document will be in the Introduction and/or on the ISO list of
patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
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.
ISO 105 was previously published in thirteen “parts”, each designated by a letter (e.g., “Part A”), with
publication dates between 1978 and 1985. Each part contained a series of “sections”, each designated by the
respective part letter and by a two-digit serial number (e.g. “Section A02”). These sections are now being
republished as separate documents, themselves designated “parts” but retaining their earlier alphanumeric
designations. A complete list of these parts is given in ISO 105-A01.
Annex A forms a normative part of this part of ISO 105.
This second edition cancels and replaces the first edition (ISO 105-C09:2001), which has been technically
revised.
The main changes are as follows:
— Percarbonate has been included as bleaching agent;
— the amendment has been incorporated;
— the document was updated editorially;
A list of all parts in the ISO 105 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
The test method in this section of ISO 105 is intended to reflect the effect of multicycle laundering using an
activated bleach detergent by domestic and commercial laundering procedures. The washes are carried out in
a similar manner to the ISO 105-C06 tests using an activated oxygen bleach and reference detergent at 60 °C.
A paper describing the development of this method has been published in the Journal of the Society of Dyers
& Colourists, Vol. 112, No.10, Oct. 1996, p. 287-292.

Part C09:
Colour fastness to domestic and commercial laundering —
Oxidative bleach response using a non-phosphate reference
detergent incorporating a low temperature bleach activator
1 Scope
This document specifies a method for determining the consumer relevant shade change of textiles, of all
kinds, (excluding silk and wool) and in all forms, to domestic/commercial laundering procedures in which a
bleach activator (oxygen bleaching system) is used. The colour fastness resulting from oxygen bleaching in
this test provides an indication of the shade change behaviour observed after multiple domestic/commercial
launderings.
This document is not applicable for the assessment of the dye staining of adjacent fabrics, where suitable
methods are described in ISO 105-A04.
