Leather - Test for adhesion of finish (ISO 11644:2022)
This document determines a procedure for determining the adhesive strength of the coverage of the leather or the adhesive resistance between two striking layers of the attribution. The process is valid for all flexible leather with a smooth surface that can be glued to a carrier without the adhesive penetrating the cover. Preliminary tests may be necessary to clarify whether these conditions are met. This test method is to be applied for covered leather with a thick coating. The procedure specified in this document is not for pigment -free articles or articles without an averted coating, such as - Nubucel leather, - Anilin leather, - fat leather, - Veloursleder, - Perforated leather.
