The tensile strength test gives a reliable indication of the quality of the leather. Improperly lubricated and partially degraded leathers give low values for tensile strength. The orientation of the specimen in relation to the backbone and the location of the specimen on the hide influence the results significantly. This test method is excellent for development, control, specification acceptance, and service evaluation of leather. This test method may not apply when the conditions of test employed differ widely from those specified in the test method.

1.1 This test method covers the determination of the load required to rupture a leather test specimen having a ½-in. (12.7-mm) width. The load to rupture divided by the original unstretched cross-sectional area gives the tensile strength. It may be used for all types of leather that are smooth and firm enough to permit accurate thickness measurements. 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 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.
