British Standard BS 10 : 1962 - Specification for Flanges and Bolting for Pipes, Valves,
and Fittings. This covers plain, boss, integrally cast or forged, and welding neck type
flanges, in ten tables. Although BS 10 is obsolescent, it remains in use for the dimensions
of light duty, economy stainless steel flanges in applications where corrosion resistance
and/or hygiene, rather than high pressures and temperatures, are the primary
considerations. The following tables detail the applicable standard dimensions from
Tables D, E, F and H of BS 10.
