EN 13491:2013 (E) 5 Introduction This document allows manufacturers to describe geosynthetic barriers on the basis of declared values for characteristics relevant to the intended use and if tested to the specified method. It also includes procedures for evaluation of conformity and factory production control. This document can also be used by designers, end-users and other interested parties as a tool to define relevant and appropriate characteristics for specifications and on-site quality control. It should be emphasised however that not all characteristics and test methods quoted in this document are suitable for the purpose of on-site quality control.
Tests for some non-mandated characteristics are still under study and will be included when the standard is revised. The term “product” used in this document refers to a geosynthetic barrier, including polymeric geosynthetic barriers, clay geosynthetic barriers and bituminous geosynthetic barriers. This document is part of a group of standards, addressing the requirements for geosynthetic barriers when used in a specific application.
Particular application cases can contain requirements about additional properties and - preferably standardised - test methods, if they are technically relevant and not conflicting with European Standards.
The design life of the product should be determined, since its function may be temporary, as a construction expediency, or permanent, for the lifetime of the structure.

The intended use of these products is to control the leakage of water through the construction wall.
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 distributors 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. 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
