DANSK DSF/PREN ISO 11644 PDF

This International Standard 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 leathers with a smooth surface that can be bonded to an adherent-plate without the adhesive penetrating into the finish. Preliminary experiments might be necessary to determine whether these conditions are met. This test method is applied to finished leathers with a thick finish-coat. The method specified in this standard does not apply to unpigmented articles or without continuous coating layer, such as – nubuk, – aniline, – pull-up, – suede, – perforated leather.
