本欧洲标准规定了隧道和地下结构施工中使用的土工织物和土工织物相关产品的相关特征，以及确定这些特性的适当试验方法。 这些土工织物或土工织物相关产品的预期用途是保护隧道和地下结构中使用的土工合成屏障。 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。 本欧洲标准可用于通过考虑到EN 1997 1（欧洲规范7）中给出的定义的范围内的因素来导出设计值，例如。安全因素产品的设计寿命应确定，因为其功能可能是临时的，作为施工方案，或永久性，在结构的一生中

This European Standard specifies the relevant characteristics of geotextiles and geotextile-related products used in the construction of tunnels and underground structures, and the appropriate test methods to determine these characteristics. The intended use of these geotextiles or geotextile-related products is to protect geosynthetic barriers used in tunnels and underground structures. 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.
