This standard BS EN ISO 20701:2018 Leather. Tests for colour fastness. Colour fastness to saliva is classified in these ICS categories:
- 59.140.30 Leather and furs

The method uses an artificial saliva solution to simulate whether colouring materials can migrate from leather to the mouth or to the mucous membranes.
