标准摘要
[中文适用范围]： 该文件规定了一种使用宽幅条样的土工合成材料（聚合物、玻璃和金属）拉伸性能测定的索引试验方法。本文件适用于大多数土工合成材料，包括编织土工织物、无纺土工织物、复合土工织物、针织土工织物、土工网、地材垫以及金属制品。它也适用于土工格栅和类似结构开放型土工织物，但试样尺寸可能需要调整。本文件不适用于聚合物或沥青基土工合成材料屏障，但它适用于黏土基土工合成材料屏障。该文件规定了一种拉伸试验方法，涵盖了拉力、延伸率的测量，并包括计算割线刚度、单位宽度最大载荷和最大力量下的应变的程序。拉力-伸长曲线上的奇异点也予以指出。本文件还包括了对干燥状态和潮湿状态试样拉伸性能测试的方法。 [外文原描述]： 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.
