CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13492:2004. The following technical change
24、s were introduced in comparison with the previous edition: The normative references were updated. Table 1 was revised. “Chemical resistance” was added to Clause 4. “Release of dangerous substances” was added to Clause 4. Annex A revised: “raw or incoming material” and Tables A.1 to A.3 were added. A
25、nnex B was revised.

BS EN 13492:2013EN 13492:2013 (E) 5 Introduction This document allows man
28、ufacturers 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, e
29、nd-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 con
30、trol. 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 barr
31、iers. 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 rele
32、vant 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. BS EN 13492:2013EN 13492:2013 (E) 6 1 Scope This European Standard specifies the
33、relevant characteristics of geosynthetic barriers, including polymeric geosynthetic barriers, clay geosynthetic barriers and bituminous geosynthetic barriers, when used as fluid barriers in the construction of liquid waste disposal sites and in the construction of transfer stations and secondary con
34、tainment 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 to control the leakage of fluids through the construction. This document is not applicable to geotextiles or geotextile-re
35、lated 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. 2 Normative references The following documents, in whole or i
