本文件规定了土工合成障碍物的相关特征，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，用作在危险液体容器和危险液体储存设施周围的危险液体容器和二次密封结构中作为流体屏障，以及确定这些障碍物的适当试验方法特点 注意本文档不适用于第二个土工合成屏障立即安装在上层土工合成屏障下面以降低屏障整体渗透性的应用。这种“双衬里”系统是相关应用程序所需特性的主题。 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。 本文档对产品的一致性进行评估。 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

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 the construction of hazardous liquid containment and secondary containment around storage facilities for hazardous liquids and the appropriate test methods to determine these characteristics. NOTE This document is not applicable to applications where one geosynthetic barrier is manufactured in direct contact with a second geosynthetic barrier in order to reduce the overall permeability of the barrier. Such "multicomponent" products are subject to the required characteristics for the relevant component. The intended use of these products is to control the leakage of fluids through the construction. This European Standard is not applicable to geotextiles or geotextile-related products as defined in EN ISO 10318-1. This European Standard 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.
