This European Standard specifies the relevant characteristics
of geotextiles and geotextile-related products used in earthwork ,foundations and retaining structures,and the appropriate test methods to determine these characteristic .
The intended use of these geotextiles or geotextile-related products i to fulfil one or more of the following functions: filtration, separation and reinforcement.The separation function is alway used in conjunction with filtration or reinforcement, accordingly separation will never be specified alone.
NOTE 1 Particular application ca e or national specifications
may contain requirements regarding additional properties and - preferably standardised - test methods, if they are technically relevant and not conflicting with European Standards.
NOTE 2 This European Standard may be used to derive design values by taking into account factor within the context of the definitions given in Eurocode 7 (ENV 1997-1), e.g.factor of
safety.The design life of the product hould be determined, since its function may be temporary, as a construction expediency, or permanent, for the lifetime of the structure.
