ISO 26082-1:2012 (IULTCS/IUP 53-1)
Leather -- Physical and mechanical test methods for the determination of soiling -- Part 1: Rubbing (Martindale) method
This standard has been revised by ISO 26082-1:2019
ISO 26082-1:2012 specifies a method for determining the resistance of all forms of leather to visible soiling through repeated contact with soiled objects. It provides a physical pretreatment routine for leathers that may be vulnerable to loss of soiling resistance while in service, prior to conducting further tests such as cleaning.
