This European Standard specifies requirements and describes test methods for pressure gauges and pressure switches. This European Standard is applicable for pressure gauges for monitoring of pilot, control, alarm and storage containers of fire extinguishing systems filled with non-liquefied inert gases or pressurized halocarbon gases. This European Standard is applicable for pressure switches for monitoring of pilot, control, alarm and storage containers of fire extinguishing systems filled with non-liquefied inert gases or pressurized halocarbon gases and remote indication of leakage. This European Standard does not cover discharge indicating pressure switches.
