Leather. Physical and mechanical test methods for the determination of soiling - Rubbing (Martindale) method Ingestion-build-132972 but its guidance can beWhat is this standard about? This document 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.
