1.1 本试验方法涵盖了测定具有以下特性的皮革试样断裂所需的载荷: 1. / 2. -在中。（12.7-mm）宽度。断裂载荷除以原始未拉伸横截面积得出抗拉强度。它可以用于所有类型的皮革，这些皮革足够光滑和牢固，可以进行精确的厚度测量。本试验方法不适用于蓝湿革。 1.2 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 抗拉强度测试提供了皮革质量的可靠指标。润滑不当和部分降解的皮革的抗拉强度值较低。 样本相对于主干的方向和样本在皮上的位置对结果有显著影响。该测试方法适用于皮革的开发、控制、规范验收和服务评估。当所采用的试验条件与试验方法中规定的条件相差很大时，本试验方法可能不适用。

1.1 This test method covers the determination of the load required to rupture a leather test specimen having a 1 / 2 -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 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 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.
