This European Standard specifies requirements for diaphragm and capsule (designated by D and C respective& see clause 12) indicating pressure gauges,vacuum gauges and combined vacuum and pressure gauges (compound gauges), from 50 to 250 nominal size with ranges up to 25 bar for the measurement of gauge pressure. A reading of zero bar is atmospheric pressure.1 bar = lo5 Pa Gauges specified have circular di& with concentric d e s for industrial 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 industriai use with common industrial fluids. It does no
