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. portable water); -- with or without pressure; -- to be installed below or above ground. NOTE: In this standard, all pressures are relative pressures, expressed in bars (100 kPa = 1 bar). 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. This standard covers pipers, fittings and accessories cast by any type of foundry process or manufactured by fabrication of cast components, as well as corresponding joints, ni a size range extending from DN 40 to DN 2000, inclusive. This standard applies to pipes, fittings and accessories which are: -- manufactured with socketed, flanged or spigot ends for jointing by means of various types of gaskets which are not within the scope of this standard; -- normally delivered externally and internally coated; -- suitable for fluid temperatures between 0 oC and 50 oC, excluding frost.
