This Standard specifies requirements for circular flanges manufactured from copper alloy, grey cast iron, ductile cast iron, or steel. It covers nominal sizes with pressure ratings for PN14, 16, 21 and 35 at operating temperatures not exceeding 80(C. The Standard also specifies requirements for jointing materials.Flanges are suitable for use on pipes, pipe fittings, valves and other equipment that are primarily intended for the conveyance or storage of water or wastewater.
