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.
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.
International Standard ISO 15703 was prepared by the Fastness Tests
Commission of the International Union of Leather Technologists and
Chemists Societies (IUF Commission, IULTCS). It is based on IUF 423
published in J. Soc. Leather Tech. Chem., 76, pp. 179-180 (1992), and
declared an official method of the IULTCS in October 1993.

INTERNATIONAL STANDARD  ISO ISO 15703:1998(E)
Leather — Tests for colour fastness — Colour fastness
to mild washing
1 Scope
This International Standard specifies a method for determining the resistance of leather to mild
washing under specified conditions.
The method is suitable for assessing the change in colour of the leather, the staining of an
adjacent textile fabric and any change in the finish of the leather.
This method can also be used leather preparation for assessing the change in any other
physical or chemical property during mild washing.

IUP 2, Sampling
3 Principle
A composite specimen of the leather and an adjacent textile fabric is agitated together with
PTFE rods in a washing liquor, rinsed and then squeezed and dried. The change in colour of
the leather and the adjacent textile fabric are assessed with the standard grey scales and, if
applicable, any changes in the finish are noted.
The general colour fastness testing principles used are in accordance with those described in
ISO 105-A01, taking into account the differences between textile substrates and leather.
