本欧洲标准规定了一种筛选试验方法，用于通过将试样暴露于高温下的水中，然后评估由这种暴露引起的性能变化，确定土工织物和土工织物相关产品对水解的阻力。它旨在作为建立最低可接受水平的耐久性的手段。 该试验适用于易于水解的任何土工织物和土工织物相关产品，特别是聚酯和聚酰胺基材料，以及制造这些土工织物的纱线。加固材料应在没有涂层的情况下进行测试，制造商应确保涂层的降解不会对纱线的退化产生不利影响或负面影响。 该方法不用于确定土工织物在高酸性或碱性条件下水解的阻力。 注意预测长期寿命的性能测试或比较不同聚合物或具有不同结构的类似聚合物的产品的性能测试可以基于相同的方法，但具有更宽的温度和持续时间

This European Standard specifies a screening test method for determining the resistance of geotextiles and geotextile-related products to hydrolysis by exposing test specimens to water at elevated temperatures, followed by an evaluation of the changes in properties resulting from such exposure. It is intended as a means of establishing a minimum acceptable level of durability. The test is applicable to any geotextile and geotextile-related product susceptible to hydrolysis, in particular polyester and polyamide based materials, and in addition to the yarns from which these geotextiles are made. Reinforcing materials shall be tested without the coating and manufacturers shall ensure that the degradation of the coating will not attack or have any negative influence on the degradation of the yarns. This method is not intended for determining the resistance of geotextiles to hydrolysis under highly acid or alkaline conditions. NOTE Performance tests to predict long-term lifetime or to compare products of different polymers or of similar polymers with differing structures can be based on the same method but with a wider range of temperatures and durations.
