ISO 10319:2015描述了使用宽幅条测定土工合成材料(聚合物,玻璃和金属)的拉伸性能的指数测试方法。它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,地球复合材料,针织土工布,地质材料,地质材料和金属制品。它也适用于土工格栅和类似的开放式土工织物,但样本尺寸可能需要更改。它不适用于聚合物或沥青土工合成屏障,同时适用于粘土土工合成屏障。
ISO 10319:2015规定了一种拉伸试验方法,涵盖了负荷伸长特性的测量,并包括计算割线刚度,单位宽度最大载荷和最大载荷下应变的程序。还显示了负载延伸曲线上的奇异点。
用于测量调理和湿试样的拉伸性能的程序包括在ISO 10319:2015中
ISO 10319:2015 describes an index test method for the determination of the tensile properties of geosynthetics (polymeric, glass, and metallic), using a wide-width strip. It 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 might need to be altered. It is not applicable to polymeric or bituminous geosynthetic barriers, while it is applicable to clay geosynthetic barriers.
ISO 10319:2015 specifies a tensile test method that covers the measurement of load elongation characteristics and includes procedures for the calculation of secant stiffness, maximum load per unit width and strain at maximum load. Singular points on the load-extension curve are also indicated.
Procedures for measuring the tensile properties of both conditioned and wet specimens are included in ISO 10319:2015.
