This European Standard specifies requirements for diaphragm and capsule (designated by D and C
respectively, 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 = 106 Pa.
Gauges specified have circular dials with concentric scales for industrial use.
The standard includes methods of test for perforrnance to be applied at type approval and
production piece tests.
The standard applies to gauges suitable for industrial use with common industrial fluids. It does not
apply to pressure gauges for oxygen or acetylene use nor gauges with electrical contacts.
Pressure gauges for welding, cutting and associated processes are not included in this standard,
but are specified in EN 562
Diese Norm legt die Anforderungen für anzeigende Druckmeßgeräte mit Platten- und Kapselfedern zum Messen von positiven und/oder negativen Überdrücken fest. Sie gilt für Nenngrößen von 50 bis 250 bar und für Anzeigebereiche bis 25 bar. Diese Norm gilt für industriell angewendete Druckmeßgeräte mit den dort üblichen Meßstoffen.
