Significance and Use
This test method is designed to measure the load required to tear a leather strap fastened in a buckle. Tanners and leather buyers have found that this test gives an indication of the resistance of leather to tearing.
This test method should be suitable for specification acceptance, design purposes, manufacturing control, development, and research. 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 this test method.
1.1 This test method is intended for use on all types of leather to determine the load required to tear a leather strap fastened in a buckle. This test method does not apply to wet blue.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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.
