DIN EN ISO 26082-1:2012-07

This document (EN ISO 26082-1:2012) has been prepared by Technical Committee CEN/TC 289 "Leather", the secretariat of which is held by UNI, in collaboration with Technical Committee ISO/TC IULTCS "International Union of Leather Technologists and Chemists Societies". The responsible committee is NA 062-05-51 AA "Anforderungen und physikalische Prüfverfahren für Leder und seine Ausgangsprodukte" ("Requirements and physical test methods of leather and ...") at the Materials Testing Standards Committee (NMP). This standard differs from DIN EN ISO 26082:2008-03 as follows: a) the standard is now Part 1 of a series of standards; b) the scope has been extended to include all forms of leather and to provide a physical pretreatment for sensitive leathers; the title has been modified accordingly; c) the standard has been editorially revised. This method is intended 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. 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 pretreatment to simulate wear and/or an after-treatment to test cleaning procedures is/are possible.
