1.1 本试验方法包括用抓法测定皮革的断裂强度。它适用于轻质、柔软的皮革；在矩形试样上测试的板革、板革或压花革；窄皮带、贴边、蕾丝和圆皮带皮革；或其他无法通过试验方法准确测试的皮革 第2209页 本试验方法不适用于湿蓝色。 1.2 由于试样在钳口中滑动，不建议使用该试验方法来破坏超过500 lbf（2200 N）的载荷。 1.3 以英寸-磅单位表示的值应视为标准值。括号中给出的值仅供参考。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 为了确定皮革是否适合其预期用途，通常需要测量皮革的强度。本试验方法适用于轻质、柔软的皮革、窄带、贴边、蕾丝和圆带皮革以及其他无法通过试验方法准确测试的皮革 第2209页 .

1.1 This test method covers the determination of the breaking strength of leather by the grab method. It is intended for use on light, soft leathers; boarded, sueded, or embossed leathers tested on a specimen in the form of a rectangle piece; narrow strap, welt, lace, and round belt leathers; or other leathers that cannot be accurately tested by Test Method D2209 . This test method does not apply to wet blue. 1.2 The test method is not recommended for breaking loads over 500 lbf (2200 N) because of slippage of the specimen in the jaws. 1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 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. 1.5 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 measurement of the strength of leather is often necessary in order to determine its suitability for its intended application. This test method is recommended for use on light, soft leathers, narrow strap, welt, lace and round belt leathers as well as others that cannot be accurately tested by Test Method D2209 .
