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 11643/IUF 434 was prepared by the European Committee for Standardization (CEN) Technical
Committee CEN/TC 289, Leather, in collaboration with the Fastness Tests Commission of the International
Union of Leather Technologists and Chemists Societies (IUF Commision, IULTCS), in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna Agreement). It is based on IUF 434
published in J. Soc. Leather Tech. Chem., 75, pp. 30-32, 1991, and was declared an official method of the
IULTCS in September 1991.
IULTCS, originally formed in 1897, is a world-wide organization of professional leather societies to further the
advancement of leather science and technology. IULTCS has three Commissions, which are responsible for
establishing international methods for the sampling and testing of leather. ISO recognizes IULTCS as an
international standardizing body for the preparation of test methods for leather.
This second edition cancels and replaces the first edition (ISO 11643:1993), which has been technically
revised. The change in the title, from Leather — Tests for colour fastness — Colour fastness of small samples
to dry-cleaning solutions to Leather — Tests for colour fastness — Colour fastness of small samples to
solvents, reflects the changes in the technology of dry cleaning from solvent-based to water-based processes.
This edition includes an option to use a petroleum hydrocarbon solvent.

Introduction
The testing of leather to determine its colour fastness to solvents can be done in several ways to achieve
different aims. Small leather samples can be tested to assess the fastness to solvents of leather dyes and
finishes, or of the finished leather itself.
The test method specified in this International Standard covers only the testing of small leather samples, in the
absence of any
