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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 6330 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 2, Cleansing, finishing
and water resistance tests.
This third edition cancels and replaces the second edition (ISO 6330:2000), which has been technically revised.
It also incorporates ISO 6330:2000/Amd.1:2008.

Introduction
This International Standard is utilized by a broad range of textile quality and performance evaluations including
but not exclusive to: smoothness appearance, dimensional change, stain release, water resistance, water
repellence, colour fastness to domestic laundering, and care labelling that are prescribed in other international
and regional test method standards.
This International Standard is also used to evaluate not only the attributes of fabrics themselves but also the
performance of apparel, home products and other textile end-products. The selection of washing and drying
machines and their associated ballast types, detergents, and other drying options are to be made according to
the international region in which the textile will be used by consumers.
NOTE Suitable machines, detergents and ballast are available commercially. If you need this information, please
contact the ISO TC 38/SC 2 Secretariat.
