British Standard BS 10 : 1962 - Specification for Flanges andBolting for Pipes, Valves, and Fittings. This covers plain, boss, integrallycast or forged, and welding neck type flanges, in ten tables. Although BS 10 isobsolescent, it remains in use for the dimensions of light duty, economystainless steel flanges in applications where corrosion resistance and/orhygiene, rather than high pressures and temperatures, are the primaryconsiderations. The following tables detail the applicable standard dimensionsfrom Tables D, E, F and H of BS 10.
