scope:

This document specifies the relevant characteristics of geosynthetic barriers, including polymeric geosynthetic barriers, clay geosynthetic barriers and bituminous geosynthetic barriers, to be used as fluid barriers 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 document is not applicable to geotextiles or geotextile-related products. This document provides for the evaluation of conformity of the product to this document. This document defines requirements to be met by manufacturers and their authorised representatives with regard to the presentation of product properties. This document does not cover applications where the geosynthetic barrier is to be in contact with water that has been treated for human consumption.
