EVS-EN 16993:2018

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.
