Leather. Test for adhesion of finish. | Status: Current

1 Scope This document specifies a method for measuring the adhesion of the finish to leather or the adhesion between two adjacent layers of the finish. The method is valid for all finished flexible leathers with a smooth surface that can be bonded to an adherent plate without the adhesive penetrating into the finish. Preliminary experiments can be necessary to determine whether these conditions are met. This test method applies to finished leathers with a thick finish-coat. The method specified in this document does not apply to unpigmented articles or articles without a continuous coating layer, such as:

• — nubuk;
• — aniline;
• — pull-up;
• — suede;
• — perforated leather.
