It also includes procedures for the evaluation of conformity and factory production control. This standard may also be used by designers, end-users and other interested parties to define which functions and conditions of use are relevant. Performance tests for several characteristics are still under study and will be included when the standard is revised. The term “product“ used in this standard refers to a geotextile or geotextile-related product. This European standard is part of a series of standards, addressing the requirements for geotextiles and geotextile-related products when used in a specific application. In annex C guidance is given on how to select the appropriate standard. 1 Scope This European Standard specifies the relevant characteristics of geotextiles and geotextile-related products used in the construction of tunnels and underground structures, and the appropriate test methods to determine these characteristics. The intended use of these geotextiles or geotextile-related products is to protect geomembranes used in tunnels and underground structures. This standard is not applicable to geomembranes. This standard provides for the evaluation of conformity of the product to this European Standard and for factory production control procedures. This standard defines requirements to be met by manufacturers and distributors with regard to the presentation of product properties. NOTE 1 Particular application cases 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 factors within the context of the definitions given in Eurocode 7 (ENV 1997-1), e.g. factors of safety. 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.

The term “product“ used in this standard refers to a geotextile or geotextile-related product. Furthermore the following term and definition apply: 3.1.1 specification any document in which the work, functions and specific conditions of use of the product are described 3.2 Abbreviations For the purpose of this European Standard the following abbreviations from EN ISO 1043-1 apply: PA: polyamide PE: polyethylene PET: polyethylene terephthalate (polyester) PP: polypropylene Furthermore the following abbreviations apply: MD: machine direction CMD: cross machine direction 4 Required characteristics and corresponding methods of test 4.1 General The main function of geotextiles and geotextile-related products used in the construction of tunnels and underground structures is protection. If a drainage or erosion control system is integrated in the construction, the requirements of the appropriate standards shall also be fulfilled (see annex C). The characteristics, their relevancy to the conditions of use, and the test methods to be used, are given in Table 1. The list of characteristics in Table 1 includes those essential to harmonisation (H), those relevant to all conditions of use (A), and those relevant to specific conditions of use (S). The indication “-“ means that the characteristic is not relevant for that function. The functions and conditions of use, corresponding with the characteristics, marked with “S“ in Table 1, are specified in 4.2. The producer of the geotextile or geotextile-related product shall provide the data based on the results of tests specified in this standard, as described in 5.1. For the assessment of durability aspects the rules described in annex B shall be observed.
