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.
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 document was prepared by the Fastness Tests Commission of the International Union of Leather
Technologists and Chemists Societies (IUF Commission, IULTCS) in collaboration with the European
Committee for Standardization (CEN) Technical Committee CEN/TC 289, Leather, the secretariat of
which is held by UNI, in accordance with the agreement on technical cooperation between ISO and CEN
(Vienna Agreement).
It is based on IUF 442 published in J. Soc. Leather Tech. Chem., 56, pp. 395–400, 1972, with a minor
amendment in 65, p. 128, 1981, declared an official method of the IULTCS in 1973 and reconfirmed in
1989.
This third edition cancels and replaces the second edition (ISO 15701:2015), which has been technically
revised.
The main changes are as follows:
— to indicate the method is applicable for polymeric materials, the general references in the text to
“plasticized poly(vinyl chloride)” have been changed to “polymeric material”;
— the note previously at the end of the Scope has been deleted;
— Clause 3 has been added;
— 5.1 has been revised to allow the use of plates of an inert material in the test apparatus.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

Leather — Tests for colour fastness — Colour fastness to
migration into polymeric material
1 S cope
This document specifies a method for assessing the propensity of dyes and pigments to migrate
from leather to a synthetic substrate by determining the transfer of colour from the leather to white
polymeric material in contact with it.
This method is applicable to leather of all kinds at any stage of processing.

4 Principle
The side under test of the leather specimen is placed on a polymeric sheet, for example a white-
pigmented sheet of plasticized poly(vinyl chloride), and the resultant composite specimen is exposed to
heat under pressure in a suitable apparatus. The transfer of colour from the leather to the white sheet is
assessed with the standard grey scale for assessing staining and, if applicable, any change in hue of the
staining is also assessed.
The use of standard sheets of polymeric material makes it possible to determine the tendency of colour
to migrate from the leather to s
