Over deze norm
This International Standard specifies, for pigmented leathers, a method for the determination of the change in colour of the leather after rubbing with a standard soiling cloth. While this method could be used for all leathers, it is particularly applicable to upholstery leathers with a finish coat, especially leather intended for automotive use. The leather specimen can be pre-treated by abrasion or flexing to simulate wear. Additionally, after soiling, the leather specimen could be subject to additional tests, such as ageing and cleaning.
