BS EN 13492:2018EN 13492:2018 (E) 6 Introduction This European Standard allows manufacturers to describe geosynthetic barriers o
40、n the basis of declared values for characteristics relevant to the intended use and if tested to the specified method. It also includes procedures for assessment and verification of constancy of performance (AVCP) including the factory production control. This document can also be used by designers,
41、 end-users and other interested parties as a tool to define relevant and appropriate characteristics for specifications. 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 geosynthe
42、tic 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
43、requirements about additional properties and preferably standardized 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 can be temporary, as construction expediency, or permanent, for the
44、 lifetime of the structure. BS EN 13492:2018EN 13492:2018 (E) 7 1 Scope This European Standard specifies the characteristics of geosynthetic barriers, including polymeric geosynthetic barriers, clay geosynthetic barriers and bituminous geosynthetic barriers, when used as fluid barriers and separatio
45、n layer in the construction of liquid waste disposal sites, and in the construction of transfer stations or secondary containment for the storage of liquid waste on a waste disposal site only and the appropriate test methods to determine these characteristics. The intended use of these products is t
46、o 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
47、 European Standard including factory production control procedures. This European Standard defines characteristics to be considered with regard to the presentation of performance. NOTE Where potable water is or can be in direct contact with the product, other relevant standards, requirements and/or
48、regulations can be considered for the design. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
