Annotation of standard text ČSN EN ISO 17228 (793854):

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
