This European Standard specifies the requirements and associated test methods applicable to ductile iron fittings, ductile iron and mild steel couplings and flange adaptors and their joints to be used with poly(vinylchloride)(PVC-U) pipes or polyethylene (PE) pipes. It is in conformity with EN 1452-1 to -5, ENV 1452-6 and -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 European Standard is not intended to cover sewerage applications, where additional requirements may be necessary.
