20、ement, at the latest by September 2018, and conflicting national standards shall be withdrawn at the latest by December 2019.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or
21、all such patent rights.This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association.For relationship with Regulation (EU) No 305/2011, see informative Annex ZA, which is an integral part of this document.According to the CEN-CENELEC
22、Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Icelan

24、riers 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 assessment and verification of constancy of performance (AVCP) including the factory production control.This document can also be used by desi
25、gners, 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 geosy
26、nthetic 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 contai
27、n 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 may be temporary, as construction expediency, or permanent, fo
28、r the lifetime of the structure.4BS EN 16993:2018EN 16993:2018 (E)1 ScopeThis 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 lay
29、er 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
30、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 const
31、ruction.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 con
32、trol procedures.This European Standard defines characteristics to be considered with regard to the presentation of performance.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
