This test method is designed to measure the load required to tear leather through two holes in the test specimen. Tanners and leather buyers have found that this test gives an indication of the resistance of leather to tearing. It is of particular value in estimating the durability of leather to withstand tearing stresses encountered in the manufacture of shoes, garments, and upholstered products. The thickness of the specimen and direction of tear relative to the backbone will affect the uniformity of the test results. This test method may not apply when the conditions of the test employed differ widely from those specified in the test method.
Область применения1.1 This test method is intended for use in determining the stitch tearing resistance of leather using a double hole tear. It is particularly applicable to lightweight leathers. This test method does not apply to wet blue.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, 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.
