土工织物和土工织物相关产品.测定耐酸和耐碱液体的筛选试验方法

[中文适用范围]： 本文件规定了在不承受外部机械应力的情况下筛选土工织物和土工织物相关产品耐液体性的方法。 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特别适用于聚酯和聚酰胺。 测试结果应根据现场条件进行解释。 本文件旨在与 ISO/TS 13434 结合使用。 注：本文件仅考虑样本完全浸没在液体中的情况。 尽管超出了本文件的范围，但是可以修改测试条件以适应特定的应用，例如气体介质。 本文件并不排除使用通过某些方法（例如风化、水萃取条件或安装损坏）进行预处理的测试样本。 [外文原描述]： 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.
