Resumen:
This European Standard specifies the requirements and associated test methods applicable to ductile iron fittings and mild steel couplings and flange adaptors and their joints to be used with poly(vinyl chloride) (PVC-U) pipes or polyethylene (PE) pipes, in conformity with EN 1452-1 to 7 and EN 12201-1 to 5 respectively, for the construction of pipelines: to convey water (e. g. water intended for human consumption); 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 is applicable to fittings which are: manufactured with socketed, flanged or spigot ends; supplied 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 is derated as given in EN 1452 and EN 12201; not intended for use in areas subjected to fire regulations. This standard covers ductile iron fittings, couplings and flange adaptors 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 60 to DN 700, to be used with pipes of external diameter from 63 mm to 710 mm. This standard also covers couplings and flange adaptors, for use with PVC-U and PE pipes, fabricated from mild steel as well as corresponding joints, in a size range extending from DN 60 to DN 700, to be used with pipes of external diameter from 63 mm to 710 mm. This standard specifies requirements for materials, dimensions and tolerances, mechanical properties and standard coatings. It also gives performance requirements for all components, including restrained and non-restrained flexible joints. Joint design and gasket shapes are outside the scope of this standard. This standard does not cover fittings intended to be used with different pipe materials other than PVC-U and PE.
