Test Method: SATRA TM167

Colour fastness to rubbing - crockmeter test

July 2017


This method is intended to determine the degree of transfer of surface colour from a material during mild dry or wet rubbing. The method is mainly applicable to fabrics, leathers, yarns and sewing threads but can be used to assess any coloured sheet material.


A test specimen of the material is rubbed by a dry or wet undyed cotton cloth which is moved linearly forwards and backwards under a constant contact force. After a set number of rubs any staining of the cotton cloth is subjectively assessed with a grey scale.
