Leather - Physical and mechanical tests - Determination of soiling with rubbing for automotive leather (ISO 26082:2007)
ISO 26082:2007 specifies, for pigmented leathers, a method for the determination of the change in colour of the leather after rubbing with a standard soiling cloth. While this method could be used for all leathers, it is particularly applicable to upholstery leathers with a finish coat, especially leather intended for automotive use.
Leder - Physikalische und mechanische Prüfungen - Bestimmung des Anschmutzens von Automobilleder durch Scheuern (ISO 26082:2007)
Diese Internationale Norm legt für pigmentierte Leder ein Verfahren zur Bestimmung der Farbänderung von Leder nach dem Reiben mit einem Standard-Anschmutzgewebe fest.
Obwohl dieses Verfahren für alle Leder gelten könnte, ist es insbesondere anwendbar auf Polsterleder mit einer Zurichtung, d. h. vor allem auf Leder für den Einsatz in der Automobilindustrie.
Der Lederprobekörper kann einer Vorbehandlung durch Scheuern oder Biegen unterzogen werden, um den Gebrauch zu simulieren. Zusätzlich könnte der Lederprobekörper nach dem Anschmutzen zusätzlichen Prü¬fungen, wie dem Altern und Reinigen unterzogen werden.
Cuir - Essais physiques et mécaniques - Détermination du salissement après frottement du cuir pour automobiles (ISO 26082:2007)
L'ISO 26082:2007 spécifie une méthode de détermination du changement de couleur des cuirs pigmentés après un frottement à l'aide d'un tissu salissant normalisé. Alors que cette méthode pourrait être employée pour tous les cuirs, elle convient particulièrement aux cuirs de garniture comportant une couche de finition, en particulier au cuir destiné à l'automobile.

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 26082/IUP 53 was prepared by the Physical Tests Commission of the International Union of Leather
Technologists and Chemists Societies (IUP Commission, IULTCS) in collaboration with the European
Committee for Standardisation (CEN) Technical Committee CEN/TC 289, Leather, the secretariat of which is
held by UNI, in accordance with the agreement on technical co-operation between ISO and CEN (Vienna
Agreement). It is based on the IULTCS method IUP 53.
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 sampling and the testing of leather. ISO recognizes IULTCS as an
international standardizing body for the preparation of test methods for leather.

IULTCS/IUP 53:2007(E)
Leather — Physical and mechanical tests — Determination of
soiling with rubbing for automotive leather
1 Scope
This International Standard specifies, for pigmented leathers, a method for the determination of the change in
colour of the leather after rubbing with a standard soiling cloth.
While this method could be used for all leathers, it is particularly applicable to upholstery leathers with a finish
coat, especially leather intended for automotive use.
The leather specimen can be pre-treated by abrasion or flexing to simulate wear. Additionally, after soiling, the
leather specimen could be subject to additional tests, such as ageing and cleaning.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

Modified Martindale method
3 Principle
A test specimen of leather is subjected to a rubbing-type soiling process under standard conditions and the
change in colour of the leather is evaluated.
A pre-treatment to simulate wear and/or an after-treatment to test cleaning procedures are possible.

4 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
4.1
soiling
change in colour of a leather specimen caused by rubbing a standard soiled fabric on the coated surface of
the leather
5 Apparatus and materials
Use normal laboratory apparatus and, in particular, the following.
5.1 Martindale abrasion apparatus, according to ISO 12947-1.
5.2 Abrasion specimen holder heads for the Martindale apparatus (5.1) as defined in ISO 12947-1. The
holder shall be fitted with loading pieces so that the sum of the mass of the applied load and the mass of the
specimen holder assembly is (795 ± 10) g. This exerts a nominal pressure of 12 kPa on the test specimen
during the test.
Use the abrasion option that forms a Lissajous figure with a (60 ± 1) mm stroke.
5.3 Pilling specimen holder heads for the Martindale apparatus (5.1), including the auxiliary mandrel
device for specimen mounting, as defined in ISO 12945-2. The pilling specimen holder shall be fitted with ring
weight and the nominal 12 kPa loading piece (as in 5.2), so that the sum of the mass of the applied load and
the mass of the specimen holder assembly is (1 010 ± 15) g. This exerts a nominal pressure of 1,6 kPa on the
test specimen during the test.
NOTE The use of the mandrel is necessary to correctly mount the soiling cloth on the holder and to avoid contact
with the soiling surface of the cloth.
Use the abrasion option that forms a Lissajous figure with a (60 ± 1) mm stroke. It should be noted that this
stroke differs from the standard machine setting for the textile pilling test.
5.4 Circular sample cutters for the specimen and soiling cloth, one cutter with a diameter of at least
140 mm and another with a diameter of at least 38 mm.
5.5 Standard soiling cloth cut to a diameter of either
⎯ at least 38 mm,
