DIN EN ISO 17228:2015-06

This International Standard specifies various ageing procedures to obtain an indication of the changes that could occur when leather is exposed to a certain environment for a prolonged time. Over time, the surface colour of leather and the leather itself change due to ageing and to the action of the surroundings on the leather. The test conditions to be used depend on the type of leather and its intended use. This procedure can also be used to age specimens for the test of dimensional change according to ISO 17130. The International Standard has been prepared by Technical Committee CEN/TC 289 "Leather", the secretariat of which is held by UNI (Italy), in collaboration with Technical Committee IULTCS "International Union of Leather Technologists and Chemists Societies". 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...") of the Materials Testing Standards Committee (NMP) at DIN.
