GB/T 4689.20-1996 specifies the determination method of the adhesion fastness of leather coatings. The standard specifies the determination principle, equipment, sample preparation and operation steps. By standardizing the test conditions and judgment standards, the adhesion performance between leather coatings and substrates is scientifically evaluated. It provides a unified technical basis for leather production quality control, product mass testing and related process improvement to ensure that the leather product coating mass meets the needs of use.
