标准范围

ISO 10319:2008描述了使用宽条测定土工合成材料拉伸性能的指数试验方法。该方法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、针织土工布和毛毡。该方法也适用于土工格栅和类似的开放式结构土工织物，但可能需要改变试样尺寸。本试验不适用于聚合物或沥青土工合成屏障，而适用于粘土土工合成屏障。拉伸试验方法包括载荷伸长特性的测量，包括割线刚度、单位宽度最大载荷和最大载荷下应变的计算程序。荷载延伸曲线上的奇点也被指出。ISO 10319:2008中包括了测量调节和湿试样拉伸性能的程序。

ISO 10319:2008 describes an index test method for the determination of the tensile properties of geosynthetics, using a wide-width strip. The method is applicable to most geosynthetics, including woven geotextiles, nonwoven geotextiles, geocomposites, knitted geotextiles and felts. The method is also applicable to geogrids and similar open-structure geotextiles, but specimen dimensions might need to be altered. This test is not applicable to polymeric or bituminous geosynthetic barriers, while it is applicable to clay geosynthetic barriers.The tensile test method 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 10319:2008.
