Test Method: SATRA TM8
Colour fastness to circular rubbing
This method is intended to assess the degree of damage (marring) and transfer of a material’s surface colour during mild dry or wet abrasion. The method is mainly applicable to footwear upper materials but can be used to assess any coloured material such as leather, plastics, and textiles.
A specimen of the material is rubbed by a rotating dry or wet circular wool felt pad under a constant contact force. The test is stopped after a predetermined number of revolutions and the damage to, or transfer of, colour is assessed subjectively using a geometric grey scale. Five versions of the test are described in this method: Dry rub. Wet rub. Perspiration rub. White spirit rub. Dry rub after wetting from the back with organic solvent.
