ISO 9863-1:2016规定了在规定压力和规定荷载板面积或规定点荷载下测定土工合成材料厚度的方法。它定义了确定厚度时的压力或载荷。 测试结果用于识别目的，并用于技术数据表和/或作为其他测试方法的一部分，例如水力性能测试。 该方法适用于所有土工合成材料。

ISO 9863-1:2016 specifies a method for the determination of the thickness of geosynthetics at specified pressures and specified load plate areas or under specified point loads. It defines the pressures or the load at which the thickness is determined. The test results are intended for identification purposes and for use in technical data sheets and/or as part of other test methods, e.g. tests of hydraulic properties. The method is applicable to all geosynthetics.
