本欧洲标准规定了在基础设施工程中用作流体屏障的土工合成障碍物的相关特征，包括聚合物，粘土和沥青土工合成屏障。道路，铁路，机场跑道以及适当的测试方法来确定这些特征。隧道及相关的地下结构见EN 13491。 这些产品的预期用途是控制流体通过结构的途径并限制任何污染，例如，通过除冰产品，地下水或水源。 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。 如果饮用水或与产品直接接触，设计人员还应参考其他相关标准，要求

This European Standard specifies the characteristics of geosynthetic barriers including polymeric geosynthetic barriers, clay geosynthetic barriers and bituminous geosynthetic barriers, used as fluid barriers and separation layer in infrastructure works, e.g. roads, railroads, runways of airports, and the appropriate test methods to determine these characteristics. Tunnels and associated underground structures are addressed in EN 13491. The intended use of these products is to control the pathway of fluid through the construction and to limit any contamination, e.g. by de-icing products, of groundwater or water sources. This European Standard 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 European Standard defines characteristics to be considered with regard to the presentation of performance. This European Standard does not cover applications where the geosynthetic barrier will 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.
