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 on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information
ISO 17228 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 412 published in J. Soc. Leather Tech. Chem., 86 pp. 325-331, 2002, and declared an
official method of the IULTCS in May 2003.
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 17228:2005), which has been technically
revised. This new version is a general update of the procedures and in Tables 1, 2, and 3 includes
additional ageing options.
Annex A is informative.

INTERNATIONAL STANDARD ISO 17228:2015(E)
Leather — Tests for colour fastness — Change in colour
with accelerated ageing
1 Scope
This International Standard specifies various ageing procedures to obtain an indication of the changes
that could occur when leather is exposed to a certain environment for a prolonged time. Over time, the
surface colour of leather and the leather itself change due to ageing and to the action of the surroundings
on the leather. The test conditions to be used depend on the type of leather and its intended use.
This procedure can also be used to age specimens for the test of dimensional change according to
ISO 17130.
2 Normative references

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.

3 Principle
A test specimen of leather is exposed to at least one of the three following conditions:
— heat (see Clause 6);
— heat and humidity (see Clause 7);
— cycles of different temperature and humidity (see Clause 8).
One or more of these procedures may take place simultaneously. The change in colour of the specimen
is assessed with the standard grey scale and, if applicable, any changes in the finish or appearance are
noted.
These procedures can also be used to prepare the leather specimen for other physical or fastness tests
after accelerated ageing. The assessment of dimension change is described in ISO 17130.
NOTE Accelerated ageing tests are for guidance only and they are not necessarily representative of long term
use at ambient temperatures.
