Description of BS 6675:1986 1986This British Standard specifies requirements for materials, design, construction, workmanship and testing of copper alloy servicing valves for water services, suitable for working pressures and temperatures from 16 bar at up to and including 30 °C to 5 bar at a maximum of 120 °C. Table 3 also gives interpolated values. The range of nominal sizes is 10, 12, 15 and 22 relating to the nominal outside diameter of copper tube in accordance with BS 2871 : Part 1. This British Standard applies to the following patterns of servicing valves:
Three patterns of servicing valve: spherical plug, tapered plug and screw-down, of nominal sizes 10, 12, 15 and 22, suitable for working pressures and temperatures from 16 bar at up to and including 30°C to 5 bar at a maximum of 120°C. The purpose of the valve is to isolate water supplies to individual sanitary appliances so that those appliances can be maintained or serviced.
