DIN EN ISO 15701:2015-07

This International Standard specifies a method for assessing the propensity of dyes and pigments to migrate from leather to a synthetic substrate by determining the transfer of colour from the leather to white plasticized poly(vinyl chloride) in contact with it. This method is suitable for leather of all kinds at any stage of processing. Tests to determine the transfer of colour from the leather using other polymeric materials (for example thermoplastic polyurethane) are also possible. This document (EN ISO 15701:2015) has been prepared by Technical Committee CEN/TC 289 "Leather", the secretariat of which is held by UNI (Italy), in collaboration with the Technical Committee "International Union of Leather Technologists and Chemists Societies (IULTCS)". This document is based on method IUF 442. The responsible German standardization committee is Working Committee NA 062-05-51 AA "Anforderungen und physikalische Prüfverfahren für Leder und seine Ausgangsprodukte" ("Requirements and physical test methods of leather and …") at DIN Standards Committee Materials Testing.
