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 air or combustive gases (e.g. natural gas or town gas) at pressures up to 16 bar; to be installed below or above ground.
NOTE 1: A combustible gas is a gas or any fuel that is in gaseous state at a temperature of 15 C at a pressure of 1 bar.
NOTE 2: In this standard, all pressures are relative pressures expressed in bars (1OOkPa = 1 bar).
This standard specifies requirements for materials, dimensions and tolerantes, mechanical properties and standard coatings of ductile iron pipes and fittings. It also gives performance requirements for all components including joints. 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 600 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; suitabie fot gas temperatutes between -15 C and 50 C.
