1.1 该试验方法将用作指数试验，以确定土工膜和/或由非织造土工布和其他防穿刺土工合成材料保护的土工膜的金字塔穿刺阻力。 1.2 该试验方法测量了由于使用具有土工膜的保护性非织造土工布而导致的金字塔穿刺阻力的增加。 1.3 以国际单位制表示的数值应视为标准。国际单位制后括号中给出的值仅供参考，不被视为标准值。 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）。 本标准的使用者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》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 抗穿刺性金字塔法是一种指数试验，用于测定无保护土工膜或用非织造土工布和其他穿刺物保护的土工膜的抗穿刺性- 保护性土工合成材料。 5.1.1 该测试方法的目的是通过提供标准标准和统一报告的基础来建立穿刺阻力的指数值。 5.2 本试验方法可用于土工膜和用非织造土工布保护的土工膜的商业装运验收试验；然而，由于有关实验室间精度的信息不完整，因此建议谨慎。

1.1 The test method is to be used as an index test to determine the pyramid puncture resistance of geomembranes and, or both, geomembranes protected by nonwoven geotextiles and other puncture-protective geosynthetics. 1.2 The test method measures the increase of the pyramid puncture resistance due to the use of protective nonwoven geotextiles with geomembranes. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered 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 ====== 5.1 The pyramid method of puncture resistance is an index test for the determination of the puncture resistance of unprotected geomembranes or geomembranes protected with nonwoven geotextiles and other puncture-protective geosynthetics. 5.1.1 The purpose of this test method is to establish an index value of puncture resistance by providing standard criteria and a basis for uniform reporting. 5.2 This test method may be used for acceptance testing of commercial shipments of geomembranes and geomembranes protected with nonwoven geotextiles; however, caution is advised since information about between-laboratory precision is incomplete.
