BS EN 13256:2016规定了土工织物和土工织物相关材料的相关特性 用于隧道和地下结构施工的产品，以及相应的测试 确定这些特征的方法。这些土工布或土工布相关产品的预期用途是保护土工合成屏障 用于隧道和地下结构。本欧洲标准不适用于EN ISO 10318-1中定义的土工合成屏障。本欧洲标准规定了对设备性能稳定性的评估和验证 该产品符合本欧洲标准和工厂生产控制程序。特定应用案例可能包含关于附加属性的要求，最好是 标准化——测试方法，如果技术相关。本欧洲标准可用于通过考虑以下因素得出设计值: EN 1997-1（欧洲法规7）中给出的定义的上下文，例如安全系数。设备的设计寿命 应确定产品，因为其功能可能是暂时的，作为施工权宜之计，或 永久性，适用于结构的使用寿命。交叉引用:EN 12224EN 12226EN 12447EN 14574EN ISO 1043-1ISO 1043-1EN ISO 3696ISO 3696EN ISO 9862ISO 9862EN ISO 10318-1ISO 10319EN ISO 10319EN ISO 10320ISO 10320EN ISO 10321ISO 10321EN ISO 10722ISO 10722EN ISO 12236ISO 12957-1ISO 12957-1ISO 12957-2EN ISO 13426-1ISO 13426-2EN ISO 13433ISO 13438ISO 10390ASTMD7409-15ASTM D4603-03（2011）e1305/2011/EUEN 1997-1EN 12225EN 13249EN 13250EN 13251EN 13252EN 13253EN 13254EN 13255EN 13257EN 13265EN 14030ISO/TR 12960:1998CEN/TR 15019EN ISO 9001ISO 14021ISO/TS 13434M/107购买本文件时提供的所有当前修订版均包括在内。

BS EN 13256:2016 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 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 product 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 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.Cross References:EN 12224EN 12226EN 12447EN 14574EN ISO 1043-1ISO 1043-1EN ISO 3696ISO 3696EN ISO 9862ISO 9862EN ISO 10318-1ISO 10318-1EN ISO 10319ISO 10319EN ISO 10320ISO 10320EN ISO 10321ISO 10321EN ISO 10722ISO 10722EN ISO 12236ISO 12236EN ISO 12957-1ISO 12957-1EN ISO 12957-2ISO 12957-2EN ISO 13426-1ISO 13426-1EN ISO 13426-2ISO 13426-2EN ISO 13433ISO 13433EN ISO 13438ISO 13438ISO 10390ASTM D7409-15ASTM D4603-03(2011) e1305/2011/EUEN 1997-1EN 12225EN 13249EN 13250EN 13251EN 13252EN 13253EN 13254EN 13255EN 13257EN 13265EN 14030ISO/TR 12960:1998CEN/TR 15019EN ISO 9001ISO 9001EN ISO 14021ISO 14021ISO/TS 13434M/107All current amendments available at time of purchase are included with the purchase of this document.
