1.1 本试验方法用于使用哑铃形试样测量沥青土工膜（BGMs）的拉伸性能。 1.2 以国际单位制表示的数值应视为标准值。括号中给出的值仅供参考。 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====== 4.1 该方法用于评估BGMs的拉伸性能。它可用于制造质量控制或验收测试。 4.2 本试验方法使用哑铃试样。本标准规定了试样的形状和尺寸。不允许有其他形状或尺寸。BGMs的其他机械性能可以使用不同的测试方法进行测量。请参阅指南 D6455 . 4.3 报告的性能是最大强度和最大强度下的伸长率。

1.1 This test method is used to measure the tensile properties of bituminous geomembranes (BGMs) using a dumbbell-shaped specimen. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 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 ====== 4.1 This method is used to evaluate the tensile properties of BGMs. It can be used for manufacturing quality control or acceptance testing. 4.2 This test method uses a dumbbell specimen. The shape and dimensions of the specimen are defined in this standard. No other shape or dimensions are allowed. Other mechanical properties of BGMs may be measured using different test methods. Refer to Guide D6455 . 4.3 The reported properties are the maximum strength and elongation at maximum strength.
