Leather - Tests for colour fastness - Change in colour with accelerated ageing (ISO 17228:2005)
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 purpose of the various ageing procedures described in this International Standard is to obtain an indication of the changes that could occur when leather is exposed to a certain environment for a prolonged time. The test conditions to be used depend on the type of leather and its intended use.
Leder - Farbechtheitsprüfungen - Farbänderung durch beschleunigtes Altern (ISO 17228:2005)
Im Laufe der Zeit verändert sich die Oberflächenfarbe von Leder und das Leder selbst durch Altern und das Einwirken der Umgebungen auf das Leder. Die verschiedenen Alterungsverfahren in der vorliegenden Internationalen Norm haben den Zweck, einen Hinweis auf Veränderungen zu erhalten, die auftreten könnten, wenn Leder über eine längere Zeit einer bestimmten Umgebung ausgesetzt ist. Die anzuwendenden Prüfbedingungen werden von der Lederart und dem vorgesehenen Verwendungszweck bestimmt.
Cuir - Essais de solidité des teintures - Changement de couleur avec vieillissement accéléré (ISO 17228:2005)
Au fil du temps, la couleur de surface du cuir et le cuir même s'altèrent en raison de leur vieillissement et de l'influence du milieu environnant sur le cuir. Les méthodes d'essai de vieillissement décrites dans l'ISO 17228:2005 ont pour objectif de décrire les dégradations susceptibles de se produire lorsque le cuir est longtemps exposé à un certain milieu. Les conditions d'essai préconisées dépendent du type de cuir et de l'usage auquel il est destiné.

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 17228 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 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.

1 Scope
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 purpose of the various ageing procedures described in this International
Standard is to obtain an indication of the changes that could occur when leather is exposed to a certain
environment for a prolonged time. The test conditions to be used depend on the type of leather and its

3 Principle
A test specimen of leather is exposed to at least one of the three following conditions:
heat (Clause 6);
heat and humidity (Clause 7);
cycles of different temperature and humidity (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 be used to prepare the leather specimen for other physical or fastness tests after
accelerated ageing.
NOTE Accelerated-ageing tests are for guidance only and they may not necessarily be representative of long-term
use at ambient temperatures.
