Annotation of standard text ČSN EN ISO 20433 (793859):
This document specifies a method to determine the amount of colour transferred from the surface of coloured leather to other surfaces by rubbing.
Two tests are carried out, one with a dry rubbing cloth and one with a wet rubbing cloth.
The method is applicable to all types of coloured leather. Since after-treatments of the leather as well as surface finishes can affect the degree of colour transfer, the test can be made before and/or after such treatments
