2、输水钢管欧盟CE认证法规

建材CPR Regulation(EU)No 305/2011

3、EN 10311:2005适用CE认证输水钢管范围

This European Standard specifies a range of jointing methods for connecting low alloy steel tubes and steel tubes and fittings for use with aqueous liquids.The following specific joint types are covered by this document:butt welded joints,welded spigot and socket(or sleeve joints),welding collars,flange joints,threaded joints,spigot and socket joints with seal and mechanical couplings.This European Standard specifies requirements for the strength and integrity of the joints and the testing of the joints.This European Standard does not specify the requirements for the tubes or the fittings.This European Standard is suitable for joints intended for the conveyance of water for human consumption,after an appropriate coating has been applied.This European Standard is not intended for use in heating networks where elevated temperature properties are required.Flexible joints which permit significant angular deflection,both during and after installation and which can accept slight offset of the centre line,are not covered by this European Standard.本欧洲标准规定了一系列连接低合金钢管和与水液体一起使用的钢管及配件的连接方法。本文件涵盖以下特定接头类型：对焊接头、焊接承插接头（或套筒接头）、焊环、法兰接头、螺纹接头、带密封和机械联轴器的承插接头和承插接头。本欧洲标准规定了接头强度和完整性以及接头测试的要求。本欧洲标准未规定管道或配件的要求。本欧洲标准适用于涂覆适当涂层后用于输送人类用水的接头。本欧洲标准不适用于要求高温性能的供暖网络。本欧洲标准不包括在安装期间和安装后允许显著角度偏转的柔性接头，以及可接受中心线轻微偏移的柔性接头。
