DIN EN ISO 17228:2012-12

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 purpose of the various ageing procedures described in this International Standard is to obtain an indication of the changes that could occur when leather is exposed to a certain environment for a prolonged time. 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/FDIS 17130.
