Test Method: SATRA TM173

Colour fastness to rubbing - reciprocating method

August 2021

SCOPE

This method is intended to assess the degree of damage (marring) and/or transfer of surface colour from a material during mild dry or wet abrasion. The method is mainly applicable to leather but can be used to assess other materials such as plastics and textiles.

PRINCIPLE

A test specimen is abraded by a dry or wet wool felt pad which is moved linearly backwards and forwards over a defined distance and under a constant contact force. After a defined number of rubs the damage to, and/or transfer of colour from the material is assessed subjectively using a geometric grey scale. Four versions of the test are described in this method:

Dry rub.

Wet rub.

Perspiration rub.

White spirit rub.
