ASTM D1516-05
(Test Method)Standard Test Method for Width of Leather
Standard Test Method for Width of Leather
SIGNIFICANCE AND USE
This test method is designed to measure the width of specimens before and after they are subjected to various tests which may change the width. A test procedure wherein such measurements could be used is the change in area of square pieces when measuring the resistance of leather to synthetic perspiration solution.
SCOPE
1.1 This test method covers determination of the width of physical test specimens and of regularly shaped units and pieces of all types of leather. This test method does not apply to wet blue.
1.2 This standard does not purport to address the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
