Leather - Fastness tests - Change in colour with accelerated ageing

摘要

Over time the surface colour of the leather and the leather itself changes due to ageing and various actions of the surroundings on the leather. The purpose of the different methods described here 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.
