1.1本试验方法旨在确定土工合成材料在恒定温度下承受持续拉伸载荷时的无侧限拉伸蠕变行为。本试验方法适用于所有土工合成材料。 1.2本试验方法测量土工合成材料试样在恒定温度下从加载时起的总伸长率。它包括测量经过处理的土工合成材料在恒温下的拉伸蠕变行为的程序以及计算拉伸蠕变曲线的方向。 1.3以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 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和健康实践，并确定监管限制的适用性。

1.1 This test method is intended for use in determining the unconfined tension creep behavior of geosynthetics at constant temperature when subjected to a sustained tensile loading. This test method is applicable to all geosynthetics. 1.2 The test method measures total elongation of the geosynthetic test specimen, from the time of loading, while being maintained at a constant temperature. It includes procedures for measuring the tension creep behavior at constant temperature of conditioned geosynthetics as well as directions for calculating tension creep curves. 1.3 The values stated in SI 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 and health practices and determine the applicability of regulatory limitations prior to use.
