1.1 本试验方法包括测定用作草坪补强垫（TRM）的土工合成材料的刚度。 1.2 该方法适用于任何纤维含量和任何数量组分的TRM。 1.3 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.4 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。 1.5 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《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====== 4.1 一般来说，本试验方法改编自为机织物开发的试验（以前指定为试验方法 D1388 ). 4.2 悬臂测试方法可能不适用于测试非常柔软或在切割边缘有明显卷曲或扭曲倾向的产品。

1.1 This test method covers the determination of the stiffness of geosynthetics used as turf reinforcement mats (TRMs). 1.2 The method is applicable to TRMs of any fiber content and any number of components. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 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 ====== 4.1 In general this test method is adapted from tests developed for woven fabrics (previously designated as Test Method D1388 ). 4.2 The cantilever test method may not be suitable for testing products that are very limp or have a marked tendency to curl or twist at a cut edge.
