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.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

ISO 15701 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. Sec. Leather Tech. Chem., 56, pp. 395-400 (1972) with a minor
amendment in 65, p. 128 (1981), and declared an official method of the IULTCS in 1973 and reconfirmed
in 1989.
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 15701:1998), which has been technically
revised with the following changes:
— use of polymeric test materials other than poly(vinyl chloride) is allowed;
— change in title to reflect the use of polymeric test materials;
— technical update of the procedures;
— revision of the loading in 4.1 and 6.1;
— inclusion of precision information as Clause 7.
Annex A is for information only.

INTERNATIONAL STANDARD ISO 15701:2015(E)
Leather — Tests for colour fastness — Colour fastness to
migration into polymeric material
1 Scope
This International Standard 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 plasticized poly(vinyl chloride) in contact with it.
This method is suitable for leather of all kinds at any stage of processing.
NOTE Tests to determine the transfer of colour from the leather using other polymeric materials (e.g.
thermoplastic polyurethane) are also possible.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 105-A01, Textiles — Tests for colour fastness — Part A01: General principles of testing
ISO 105-A03, Textiles — Tests for colour fastness — Part A03: Grey scale for assessing staining
ISO 105-A04, Textiles — Tests for colour fastness — Part A04: Method for the instrumental assessment of
the degree of staining of adjacent fabrics
ISO 2418, Leather — Chemical, physical and mechanical and fastness tests — Sampling location
3 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 plasticized poly(vinyl chloride) makes it possible to determine the tendency
of colour to migrate from the leather to synthetic materials used in conjunction with the leather.
If the leather has a finish, the test may be carried out with the finish intact or broken.
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.
4 Apparatus and materials
Normal laboratory apparatus and:
4.1 Test apparatus, in which the composite specimen can be subjected, between glass plates, to a
uniform pressure of (81,7 ± 4,0) kPa using an approximately 5 kg load weight. The pressure tolerance
includes a maximal supplementary mass due to the glass plates of 250 g. The construction of the test
apparatus shall ensure that the pressure is constant during the whole test.
ISO 15701:2015(E)
IULTCS/IUF 442:2015(E)
NOTE 1 The 81,7 kPa pressure from a 5 kg load weight is equivalent to 833 g/cm on the (30 × 20) mm leather
specimen.
