This Standard specifies requirements for circular flanges manufactured from copper alloy, ductile cast iron, grey cast iron, or steel. It covers nominal sizes (see Table 2.1) with pressure ratings for Classes 14, 16, 21 or 35 at temperatures not exceeding 80C. The flanges are for use on pipes, pipe fittings, valves and other equipment that are primarily intended for the conveyance or storage of water or wastewater. NOTE: Guidelines to purchasers on information that should be supplied at the time of enquiry ororder are detailed in Appendix A.
