This British Standard specifies general requirements for pressure and vacuum switches for industrial use and gives performance characteristics that are to be stated by the manufacturer. It is applicable to switches suitable for use up to 1 000 bar and with fluids and in atmospheres that are non-flammable, non-corrosive and non-toxic. It is also applicable to switches suitable for higher pressures, other fluids or atmospheres if in other respects the switches meet the requirements of their special application.
The tests to check compliance with the performance requirements of this standard are type tests (see clause 9) and routine tests (see clause 10).
This standard is not applicable to pressure difference switches, pressure indicating devices or switches with non-electrical outputs.
For switches for use in explosive atmospheres, additional requirements are specified in BS 4683 and BS 5501.
