25、(E) 5 Introduction This European Standard allows manufacturers to describe geotextiles and geotextile-related products 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 the assessment and verificati
26、on of constancy of performance and factory production control. This European Standard may also be used by designers, end-users and other interested parties to define which functions and conditions of use are relevant. The term “product” used in this European Standard refers to a geotextile or geotex
27、tile-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. Annex C provides guidance on how to select the appropriate standard. BS EN 13256:2016EN 13256:2016 (E) 6 1 S
28、cope 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-r
29、elated products is to protect geosynthetic barriers used in tunnels and underground structures. This European Standard is not applicable to geosynthetic barriers, as defined in EN ISO 10318-1. This European Standard provides for the assessment and verification of constancy of performance of the prod
30、uct to this European Standard and for factory production control procedures. Particular application cases may contain requirements regarding additional properties and preferably standardized test methods, if they are technically relevant. This European Standard may be used to derive design values by
31、 taking into account factors within the context of the definitions given in EN 1997-1 (Eurocode 7), 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. 2 Norma

45、cts 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. The specification shall define which conditions of use are relevant (see
46、 Table 1). The producer shall provide the necessary data based on the requirements and test methods specified in this European Standard, as described in 5.1. The characteristics, their relevance to the conditions of use, and the test methods to be used, are specified in Table 1. The list of characte
47、ristics in Table 1 includes 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. Where, for the same property, data for more than one function shall be provided, the follo
48、wing ranking order shall be observed: A overrules S, and S overrules “”. The functions and conditions of use, corresponding with the S-coded characteristics in Table 1, are specified in 4.3. Durability shall be assessed in accordance with the requirements of Annex B. 4.2 Selection of the appropriate
49、 standard in a specific application Guidelines for the selection of the appropriate standard in a specific application are given in Annex C.
