This European Standard specifies the requirements and associated test methods applicable to ductile iron pipes, fittings, accessories and their joints for the construction of pipelines: - to convey water (e. g. for drinking water pipelines, fire protection, snow guns, irrigation, hydroelectric, reused water pipelines, etc…) - with or without pressure ; - to be installed below or above ground. This standard is applicable to pipes, fittings and accessories which are : - manufactured with socketed, flanged or spigot ends; - normally delivered externally and internally coated ; - suitable for fluid temperatures between 0 °C and 50 °C, excluding frost. This standard covers pipes, fittings ast by any type of foundry process or manufactured by fabrication of cast components, as well as corresponding joints and accessories, in a size range extending from DN 40 to DN 2 000, inclusive. This standard specifies requirements for materials, dimensions and tolerances, mechanical properties and standard coatings of ductile iron pipes and fittings. It also gives performance requirements for all components including joints. Joint design and gasket shapes are outside the scope of this standard. In addition reference is made to the performance requirements of couplings, flange adaptors and saddles manufactured only for use with ductile iron pipes and fittings NOTE In this standard, all pressures are relative pressures, expressed in bars (100 kPa = 1 bar).
