This European Standard specifies the requirements and associated test methods applicable to ductile iron fittings and their joints to be used with poly(vinyl chloride) (PVC-U) pipes or polyethylene (PE) pipes, in conformity withEN 1452-1 to 7 and prEN 12201-1 to 7 respectively, for the construction of pipelines :_ to convey water (e.g. potable water) ;_ with or without pressure ;_ to be installed below or above ground, inside or outside buildings.This standard is not intended to cover sewerage applications, where additional requirements may be necessary.This standard specifies requirements for materials, dimensions and tolerances, mechanical properties and standard coatings of ductile iron fittings. It also gives performance requirements for all components, including restrained and non-restrained flexible joints.This standard covers fittings 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 700, to be used with pipes of external diameter from 40 mm to 710 mm.This standard applies to fittings which are :_ manufactured with socketed ends (for push-in or mechanical joints), flanged ends and/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 PE and PVC-U pipes with fluid temperatures between 0°C and 25°C,excluding frost, and for pressures up to 16 bar (PFA). For higher temperatures (up to 45°C for PVC-U or 40°C for PE) the PFA isderated as given in EN 1452 and prEN 12201.This standard does not cover ductile iron fittings intended to be used with different pipe materials other than PVC-U and PE.NOTE 1 Temperature limitations and pressure limitations are those coming from the PVC-U or PE pipes.NOTE 2 In this standard, all pressures are relative gauge pressures, expressed in bars (100 kPa = 10 bar)
