Leather - Tests for colour fastness - Colour fastness of small samples to solvents (ISO 11643:2009)
ISO 11643:2009 specifies a method for determining the resistance to solvent solutions of the colour and finish of unused, and not yet cleaned, leather. It does not cover composite materials or complete leather garments. It is not intended to be used to give any guidance on the process to be employed for cleaning garments.
During the test, the colour of the leather can change and the adjacent fabric used can become stained. Additionally, the finish of the leather can be damaged.
The presence of absorbed water in the leather, adjacent fabric or solvent has not been found to be a critical factor in assessing the colour fastness.
Leder - Farbechtheitsprüfungen - Farbechtheit kleiner Proben gegenüber Lösemitteln (ISO 11643:2009)
Diese Internationale Norm legt ein Verfahren zur Bestimmung der Beständigkeit von Farbe und Zurichtung von neuem und noch nicht gereinigtem Leder gegenüber Lösemittel fest. Sie umfasst nicht zusammengefügte Materialien oder vollständige Lederbekleidung. Sie ist nicht für die Verwendung als Anleitung für den Prozess vorgesehen, der zur Reinigung von Bekleidung anzuwenden ist.
Während der Prüfung kann sich die Farbe des Leders ändern und das verwendete Begleitgewebe kann anbluten. Darüber hinaus kann die Zurichtung des Leders beschädigt werden.
Das Vorhandensein von absorbiertem Wasser im Leder, Begleitgewebe oder Lösemittel hat sich als unkritischer Faktor für die Bewertung der Farbechtheit herausgestellt.
Cuir - Essais de solidité des teintures - Solidité des teintures de petits échantillons aux solvants (ISO 11643:2009)
L'ISO 11643:2009 spécifie une méthode permettant de déterminer la résistance aux solutions de solvants de la couleur et du finissage du cuir neuf, avant utilisation, et avant le premier nettoyage. Elle ne concerne pas les matériaux composites ou les vêtements de cuir complets. Elle n'est pas destinée à servir de guide quant au choix du procédé à appliquer pour le nettoyage des articles d'habillement.
Au cours de l'essai, la couleur du cuir peut varier et le tissu témoin utilisé peut se tacher. De plus, le finissage du cuir peut être endommagé.
La présence d'eau absorbée dans le cuir, le tissu témoin ou le solvant n'est pas considérée comme étant un facteur critique pour l'évaluation de la solidité des teintures.

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 other materials (accessories, adhesives, etc.), that can influence the cleanability with solvents
of the finished article. Moreover, it does not consider changes in leather properties, such as the handling
characteristics or area stability, as the samples are too small. It must not therefore be used to provide
guidance as to the process to be employed for cleaning or spot and stain removal with solvents on complete
garments.
Part of the colour of leather is due to the oil content. When treated with solvents some of the colour change is
due to the loss of oil into the solvent. The objective of the treatment with triolein is to restore the colour due to
changes in the oil content of the leather. The method with one level of triolein can give a guideline for re-oiling.
Since different leathers can have different oil contents, a range of re-oiling tests would be necessary to
establish the correct re-oiling level.

INTERNATIONAL STANDARD
IULTCS/IUF 434:2009(E)
Leather — Tests for colour fastness — Colour fastness of small
samples to solvents
1 Scope
This International Standard specifies a method for determining the resistance to solvent solutions of the colour
and finish of unused, and not yet cleaned, leather. It does not cover composite materials or complete leather
garments. It is not intended to be used to give any guidance on the process to be employed for cleaning
garments.
During the test, the colour of the leather can change and the adjacent fabric used can become stained.
Additionally, the finish of the leather can be damaged.
The presence of absorbed water in the leather, adjacent fabric or solvent has not been found to be a critical
factor in assessing the colour fastness.

3 Principle
A composite specimen of the leather and an adjacent fabric is agitated, together with PTFE rods, in a solvent,
which may contain triolein (and possibly a detergent), then squeezed and dried at ambient temperature. The
change in colour of the specimen and staining of the adjacent fabric are assessed with the grey scales and (if
applicable) any changes
