Leather. Tests for colour fastness. Colour fastness of small samples to solvents not-eligible 11 - Refractory Materials for1 Scope This International Standard specifies a method for determining the resistance to solvent solutions of the colour and finish of unused, and not yet cleaned, leather. It does not cover composite materials or complete leather garments. It is not intended to be used to give any guidance on the process to be employed for cleaning garments. During the test, the colour of the leather can change and the adjacent fabric used can become stained.
