23、n Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2018, and conflicting national standards shall be withdrawn at the latest by December 2019. Attention is drawn to the possibility that some of the ele

24、ments of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights.

BS EN 13491:2018EN 13491:2018 (E) 4 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 procedure

31、s for assessment and verification of constancy of performance (AVCP) including the 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. Tests for some non-manda

32、ted 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

33、 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 standardized test methods, if they are technically relevant and not conflicting with Euro

34、pean Standards. The design life of the product should be determined, since its function can be temporary, as construction expediency, or permanent, for the lifetime of the structure. BS EN 13491:2018EN 13491:2018 (E) 5 1 Scope This document specifies the characteristics of geosynthetic barriers, inc

35、luding polymeric geosynthetic barriers, clay geosynthetic barriers and bituminous geosynthetic barriers, when used as fluid barriers and separation layer in the construction of tunnels and associated underground structures, and the appropriate test methods to determine these characteristics. The int

36、ended use of these products is to control the leakage of fluid through the construction. This document is not applicable to geotextiles or geotextile-related products as defined in EN ISO 10318-1. This document provides for the assessment and verification of constancy of performance (AVCP) of the pr

37、oduct to this European Standard including factory production control procedures. This document defines characteristics to be considered with regard to the presentation of performance. This document does not cover applications where the geosynthetic barrier is to be in contact with water that has bee

38、n treated for human consumption. NOTE Where potable water is or can be in direct contact with the product, other relevant standards, requirements and/or regulations can be considered for the design. 2 Normative references The following documents, in whole or in part, are normatively referenced in th
