This European Standard specifies the requirements and associated test methods applicable to ductile iron pipes, fittings, accessories and their joints used for the construction of pipelines outside buildings: -  to convey air or combustible gases (e.g. natural gas or town gas) at pressures up to 16 bar; -  to be installed below or above ground. This European Standard applies to pipes, fittings and accessories which are: -  manufactured with socketed, flanged or spigot ends; -  normally delivered externally and internally coated; -  suitable for gas temperatures between − 15 °C and 50 °C. This European 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 600 inclusive. This European 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 shape are outside the scope of this European Standard.
