This standard specifies requirements for Bourdon tube (designated by B) indicating pressure gauges, vacuum gauges and combined vacuum and pressure gauges (compound gauges), with circular, spiral or coiled forms, from 40 to 250 nominal size with ranges up to 1600 bar for the measurement of gauge pressure. A reading of zero bar is atmospheric pressure. A reading of zero bar is atmospheric pressure. 1 bar = 10 5 Pa . Gauges specified have circular dials with concentric scales for industrial and test use. The standard includes methods of test for performance to be applied at type approval and production piece tests. The standard applies to gauges suitable for industrial use with common industrial fluids. It applies also to liquid-filled gauges, gauges for high pressure gases and gauges for use with oxygen or acetylene. It does not apply to pressure gauges with electrical contacts. Pressure gauges for welding, cutting and associated processes are not included in this standard, but are specified in EN 562.
