ISO 10321:2008规定了使用宽条测定土工合成材料接缝和接缝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。它也适用于土工格栅，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。 ISO 10321:2008中规定的方法量化了土工合成材料之间接缝或接缝的抗拉强度。它可以提供数据来指示可以达到的接头或接缝抗拉强度。 其中包括测量处理后试样和湿试样拉伸性能的程序。

ISO 10321:2008 specifies an index test method for determination of the tensile properties of joints and seams in geosynthetics, using a wide-width strip. The method is applicable to most geosynthetics. It is also applicable to geogrids, but the specimen dimensions may need to be altered. This test is not applicable to polymeric or bituminous geosynthetic barriers. The method specified in ISO 10321:2008 quantifies the tensile strength of a joint or seam between geosynthetics. It can provide data to indicate the joint or seam tensile strength which can be achieved. Procedures for measuring the tensile properties of both conditioned and wet specimens are included.
