ISO 105-X12 Colour fastness to rubbing (Crockmeter)
The test involves mounting the dyed or printed leather on a lower platform and then rubbing 10 cycles with a white fabric, which is mounted on a peg in the upper rubbing arm. The next step involves determining the extent of color that rubs away onto the white fabric against a color transference scale.

ISO 11640 (Veslic) Colour fastness to cycles of to-and-fro rubbing

The principle of the method specified is rubbing one side of the leather to be tested with pieces of reference wool felt under a given pressure for a given number of forward and backward motions, assessing the change in colour of the pieces of felt and of the leather with the grey scales. Any other visible change in or damage to the surface of the leather is also reported.

ISO 105-B02 Colour fastness to artificial light: Xenon arc fading lamp test
Specifies a method intended for determining the resistance of the colour of leather to the action of an artificial light source representative of natural daylight (D65)

ISO 2589 Determination of thickness
Specifies a method for determining the thickness of leather

ISO 11641 Colour fastness to perspiration
The principle of the method specified is soaking a leather specimen and also a piece of adjacent fabric, laid against each side to be tested, in artificial perspiration solution, leaving the composite specimen under pressure for a specified time in a suitable apparatus, drying the leather specimen and adjacent fabric, and assessing the change in colour of the specimen and the staining of the adjacent fabric with the grey scales.

ISO 15703 Colour fastness to mild washing
Fastness of the colour of leather to hand washing is the resistance to washing under mild domestic laundering in water.

ISO 3376 Determination of tensile strength and percentage extension
Specifies a method for determining the tensile strength, elongation at a specified load and elongation at break of leather

ISO 12947 abrasion resistance
Determination of the abrasion resistance of fabrics by the Martindale method
