Over deze norm
Specifies the requirements and associated test methods applicable to ductile iron pipes, fittings, accessoiries and their joints for the construction of pipelines: - to convey water (e.g. potable water);-with or without pressure;-to be installed below or above ground. This standard applies 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, exclusing frost. This standard covers pipes, fittings and accessories cast by any type of foundry process or manufactured by fabrication of cast components, as well as corresponding joints, in a size range extending from DN 40 to DN 2000, 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. Note: in this standard, all pressures are relative pressures, expressed in bars (100 kPa=1 bar).
