3.Terms and definitions:For the purposes of this document, the leather terms and definitions given in EN 15987 shall apply.
4.Principle:One side of the leather specimen is rubbed with pieces of reference wool felt under a given pressure fora given number of forward and backward motions.
The degree of colour staining of the wool felt and the change in colour of the leather are assessed withgrey scales.Any other visible change in, or damage to, the surface of the leather is also reported.
The general colour fastness testing principles shall be in accordance with those described inISO 105-A01, taking into account that the substrate is leather.BS EN ISO 11640 pdf download.
