本文件规定了土工织物和土工织物相关产品在不承受外部机械应力的情况下对液体阻力的筛选方法。 适用于所有土工布及土工布相关产品。方法A特别适用于聚酰胺，方法B适用于聚酯和聚酰胺。测试结果旨在根据现场条件进行解释。 本文件拟与ISO/TS 13434结合使用。 注:本文件仅考虑试样完全浸入液体中的情况。虽然不在本文件的范围内，但可以修改试验条件以适应特定应用，例如气体介质。本文件不排除使用通过某种方法预处理的试样，例如通过风化、水萃取条件或安装损坏。

This document specifies methods for screening the resistance of geotextile and geotextile-related products to liquids while not subjecting them to external mechanical stress. It is applicable to all geotextiles and geotextile-related products. Method A applies particularly to polyamides and method B to polyesters and polyamides. The test results are intended to be interpreted in the context of site conditions. This document is intended to be used in conjunction with ISO/TS 13434. NOTE This document only considers conditions where the specimens are fully immersed in the liquids. Though outside the scope of this document, the test conditions can be modified to accommodate particular applications, e.g. gaseous media. This document does not preclude use for test specimens that are pre-treated by some method, e.g. by weathering, aqueous extraction conditions or installation damage.
