本欧洲标准规定了侵蚀控制工程中使用的土工织物和土工织物相关产品的相关特征，以防止由于交替的液压梯度而将细分级材料迁移到较粗的材料层，以及确定这些特性的适当的测试方法。 本欧洲标准涵盖沿海保护和银行护岸申请。该欧洲标准不包括表面侵蚀，其中土工织物或土工织物相关产品位于表面。 这些土工织物或土工织物相关产品的预期用途是满足以下一个或多个功能:过滤，分离和加固。分离功能将始终与过滤或增强结合发生，因此不会单独指定。 本欧洲标准不适用于EN ISO 10318 1中定义的土工合成障碍物。 本欧洲标准规定了对本欧洲标准的产品性能稳定性和工厂生产控制程序的评估和验证。 具体的应用案例可能包含有关附加属性的要求，如果与技术上相关，则可能包含“最佳标准化”测试方法的要求。 这个欧元

This European Standard specifies the relevant characteristics of geotextiles and geotextile-related products used in erosion control works for preventing the migration of fine-graded material into layers of coarser material due to alternating hydraulic gradients, and the appropriate test methods to determine these characteristics. This European Standard covers applications in coastal protection and bank revetment. This European Standard does not cover surface erosion, where the geotextile or geotextile-related product is located at the surface. The intended use of these geotextiles or geotextile-related products is to fulfil one or more of the following functions: filtration, separation, and reinforcement. The separation function will always occur in conjunction with filtration or reinforcement, and hence will not be specified alone. This European Standard is not applicable to geosynthetic barriers, as defined in EN ISO 10318 1. This European Standard provides for the assessment and verification of constancy of performance of the product to this European Standard and for factory production control procedures. Particular application cases may contain requirements regarding additional properties and – preferably standardized – test methods, if they are technically relevant. This European Standard may be used to derive design values by taking into account factors within the context of the definitions given in EN 1997 1 (Eurocode 7), e.g. factors of safety. The design life of the product should be determined, since its function may be temporary, as a construction expediency, or permanent, for the lifetime of the structure.
