Področje projekta (angleško): This document specifies the requirements and associated test methods applicable to wide tolerance ductile iron couplings and wide tolerance flange adaptors intended for use with pipe components made from a number of pipe materials (ductile iron, grey iron, PE, PVC-U, steel, fibre-cement), for providing a leak tight seal over a wide range of pipe external diameters : - 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 or gas applications, where other requirements may be necessary. This standard specifies requirements for materials, dimensions and tolerances, mechanical properties and standard coatings of ductile iron products. This standard covers ductile iron products 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, for an allowable operating pressure (PFA) up to 16 bar, for fluid temperatures between 0 °C and 25 °C excluding frost. For higher temperatures, up to 50 °C, additional type testing should be carried out. It also gives performance requirements and associated test methods for restrained and non-restrained flexible joints. Joint design and gasket shapes are outside the scope of this standard. NOTE 1 PFA may be limited depending on pipe materials effectively connected. NOTE 2 In this standard, all pressures are relative gauge pressures, expressed in bars (100 kPa = 1 bar). NOTE 3 EN 545 gives the specifications for the ductile iron fittings to be used with ductile iron pipes. NOTE 4 EN 12842 gives the specifications for the ductile iron fittings to be used with PVC-U and PE pipes.
