ZHTest Method: SATRA TM304
Qualitative tests for soluble colour in upper and lining materials
February 2023
SCOPE
This method is intended to determine qualitatively whether or not a material will lose colour in wear, leading to either a change in colour of the material itself or the staining of a material with which it is in contact. It is mainly applicable to leather but may be used for other upper and lining materials, see clause 8.1.
PRINCIPLE
Test specimens are extracted with boiling solutions of water and toluene, see clause 8.2. Artificial perspiration can be used as an additional extraction liquid. The extent of the colour changes of the liquids is used as a qualitative guide as to whether or not the material will lose colour in wear.
