A reference wool felt piece is rubbed against one side of the leather sample under pressure, moving back and forth a certain number of times. The degree of staining of the wool felt and the color change of the leather are assessed using a grey scale. Any other visible changes or damage to the leather surface are also reported.
General color fastness test principles should be in accordance with those specified in ISO 105-A01, taking into account that the substrate is leather.
