Description
ISO 11644 Leather — Test for Adhesion of Finish
ISO 11644 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 valid for finished leathers with a finish-coat thickness of at least 15 µm.
Tensile-testing machine, incorporating the following features: a force range appropriate to the specimen under test; a uniform speed of separation of the jaws of
(100 +- 5) mm/min; provision for recording a force-distance diagram during the test
*** Before conducting this ISO standard , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
***PARSROS offers several types of grips and fixtures which will enable you to perform a variety of tests
that are accurate and repeatable
