本欧洲标准规定了在水库和水坝建设中用作饮用水，新鲜或盐水的流体屏障的土工合成壁垒的相关特征，包括聚合物合成壁垒，粘土土工合成屏障和沥青土工合成屏障，以及适当的试验确定这些特征的方法。 这些产品的预期用途是控制通过施工的水的泄漏。 本欧洲标准不适用于土工织物或土工织物相关产品。 本欧洲标准规定了产品符合本文件的评估。 本欧洲标准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。 本欧洲标准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 European Standard specifies the relevant characteristics of geosynthetic barriers, including polymeric geosynthetic barriers, clay geosynthetic barriers and bituminous geosynthetic barriers, to be used as fluid barriers for potable, fresh or saline water, in the construction of reservoirs and dams, and the appropriate test methods to determine these characteristics. The intended use of these products is to control the leakage of water through the construction. This European Standard is not applicable to geotextiles or geotextile-related products. This European Standard provides for the evaluation of conformity of the product to this document. This European Standard defines requirements to be met by manufacturers and their authorised representatives with regard to the presentation of product properties. This European Standard does not cover applications where the geosynthetic barrier is to be in contact with water that has been treated for human consumption. Where potable water is or may be in direct contact with the product the designer should also refer to other relevant standards, requirements and/or regulations.
