Leather - Physical and mechanical test methods for the determination of soiling - Part 1: Rubbing (Martindale) method (ISO 26082-1:2012)
ISO 26082-1:2012 specifies a method for determining the resistance of all forms of leather to visible soiling through repeated contact with soiled objects. It provides a physical pretreatment routine for leathers that may be vulnerable to loss of soiling resistance while in service, prior to conducting further tests such as cleaning.
Leder - Physikalische und mechanische Prüfverfahren zur Bestimmung des Anschmutzens - Teil 1: Martindale-Verfahren (ISO 26082-1:2012)
Dieses Verfahren ist dazu vorgesehen, die Beständigkeit aller Arten von Leder gegen ein sichtbares
Anschmutzen durch wiederholten Kontakt mit angeschmutzten Gegenständen zu bestimmen. Für Leder, die
ihre Anschmutzbeständigkeit im Gebrauch verlieren können, enthält das Verfahren Möglichkeiten zur
physikalischen Vorbehandlung vor weiteren Prüfungen, wie dem Reinigen.

Cuir - Méthodes d'essai physique et mécanique de détermination de la salissure - Partie 1: Méthode par frottement (Martindale) (ISO 26082-1:2012)
L'ISO 26082-1:2012 spécifie une méthode de détermination de la résistance à la salissure visible de toute forme de cuir par mise en contact répétée avec des objets salissants. Elle prévoit un prétraitement physique pour les cuirs susceptibles de perdre leur résistance à la salissure en cours d'utilisation, avant la réalisation d'autres essais comme le nettoyage.
Usnje - Fizikalno in mehansko preskušanje za ugotavljanje madežev - 1. del: Metoda (Martindale) z brisanjem usnja (ISO 26082-1:2012)

ISO 26082-1:2012(E) IULTCS/IUP 53-1:2012(E) iv © ISO 2012 – All rights reserved 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 26082-1 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 289, Leather, in collaboration with the Physical Tests Commission of the International Union of Leather Technologists and Chemists Societies (IUP Commission, IULTCS) in accordance with the agreement on technical cooperation between ISO and CEN (Vienna Agreement). 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. This first edition of ISO 26082-1 cancels and replaces ISO 26082:2007, which has been technically revised. It has a modified title and small changes have been made to 5.3, 5.7 and 6.2. ISO 26082 consists of the following parts, under the general title Leather — Physical and mechanical test methods for the determination of soiling: Part 1: Rubbing (Martindale) method Part 2: Tumbling method

It provides a physical pretreatment routine for leathers that may be vulnerable to loss of soiling resistance while in service, prior to conducting further tests such as cleaning. 2 Normative references The following referenced documents are indispensable for the application of this document.

A pretreatment to simulate wear and/or an after-treatment to test cleaning procedures is possible. SIST EN ISO 26082-1:2012
ISO 26082-1:2012(E) IULTCS/IUP 53-1:2012(E) 2 © ISO 2012 – All rights reserved 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 Normal laboratory apparatus and, in particular, the following. 5.1 Martindale abrasion apparatus, as specified in 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. 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 traces 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. NOTE This might not be possible with all Martindale machines, particularly old machines. 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 for the abrasion specimen holder of the Martindale apparatus (5.2), or at least 140 mm for the pilling specimen holder of the Martindale apparatus (5.3).
The standard soiling test cloth is impregnated with a soilant mix of carbon black and olive oil. Alternative soiling cloths can be specified by the client. NOTE Various standard soiling cloths are commercially available, see Annex A.
5.6 Polyetherurethane foam underlay, as specified in ISO 12947-1, cut to a diameter of at least 38 mm, for the abrasion specimen holder of the Martindale apparatus (5.2). 5.7 Wool felt underlay, as specified in ISO 12945-2, cut to a diameter of (90 ± 1) mm, for the pilling specimen holder (5.3). This is available pre-cut to size. 5.8 Wool felt underlay, as specified in ISO 12947-1, cut to a diameter of at least 140 mm, for the abrading table of the Martindale apparatus (5.1).
