本文件规定了用作隧道和相关地下结构施工中的流体屏障的土工合成屏障的相关特征，包括聚合物合成屏障，粘土土工合成屏障和沥青土工合成屏障，以及确定这些特性的适当测试方法。 这些产品的预期用途是控制流体通过施工的泄漏。 本文档不适用于EN ISO 10318 1中定义的土工织物或土工织物相关产品。 本文档规定了对本欧洲标准产品的性能稳定性和工厂生产控制程序的评估和验证。 本文件定义了制造商及其授权代表在产品属性介绍方面要满足的要求。 本文件不包括土工合成屏障与被人类消费的水接触的应用。 如果饮用水可能或可能与产品直接接触，设计人员还应参考其他相关标准，要求和/或法规

This document specifies the characteristics of geosynthetic barriers, including polymeric geosynthetic barriers, clay geosynthetic barriers and bituminous geosynthetic barriers, when used as fluid barriers and separation layer in the construction of tunnels and associated underground structures, and the appropriate test methods to determine these characteristics. The intended use of these products is to control the leakage of fluid through the construction. This document is not applicable to geotextiles or geotextile-related products as defined in EN ISO 10318 1. This document provides for the assessment and verification of constancy of performance (AVCP) of the product to this European Standard including factory production control procedures. This document defines characteristics to be considered with regard to the presentation of performance. This document does not cover applications where the geosynthetic barrier is to be in contact with water that has been treated for human consumption. NOTE Where potable water is or can be in direct contact with the product, other relevant standards, requirements and/or regulations can be considered for the design.
