本文件规定了一种使用宽幅条测定土工合成材料（聚合物、玻璃和金属）拉伸性能的指数试验方法。本文件适用于大多数土工合成材料，包括机织土工布、非织造土工布，土工复合材料，针织土工布和土工网，土工织物和金属制品。它也适用于土工格栅和类似的开放式结构土工布，但可能需要改变试样尺寸。它不适用于聚合物或沥青土工合成材料屏障，但适用于粘土土工合成屏障。 本文件规定了一种拉伸试验方法，该方法涵盖了张力、伸长率特性的测量，并包括割线刚度、单位宽度最大载荷和最大力下应变的计算程序。还指出了张力-伸长曲线上的奇点。 本文件包括测量调节和湿试样拉伸性能的程序。

This document specifies an index test method for the determination of the tensile properties of geosynthetics (polymeric, glass and metallic), using a wide-width strip. This document is applicable to most geosynthetics, including woven geotextiles, nonwoven geotextiles, geocomposites, knitted geotextiles, geonets, geomats and metallic products. It is also applicable to geogrids and similar open-structure geotextiles, but specimen dimensions will possibly need to be altered. It is not applicable to polymeric or bituminous geosynthetic barriers, but it is applicable to clay geosynthetic barriers. This document specifies a tensile test method that covers the measurement of tensile force, elongation characteristics and includes procedures for the calculation of secant stiffness, maximum load per unit width and strain at maximum force. Singular points on the tensile force-extension curve are also indicated. Procedures for measuring the tensile properties of both conditioned and wet specimens are included in this document.
