1.1 本试验方法适用于所有类型的皮革，以确定撕裂固定在皮带扣中的皮带所需的负载。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====== 2.1 本试验方法旨在测量撕裂固定在皮带扣中的皮带所需的负载。制革商和皮革购买者发现，该测试表明皮革的抗撕裂性。 2.2 该测试方法应适用于规范验收、设计目的、制造控制、开发和研究。试样厚度和相对于主干的撕裂方向将影响测试结果的均匀性。 当所采用的试验条件与本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 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, 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 ====== 2.1 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. 2.2 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.
