Fixed firefighting systems. Components for gas extinguishing systems - Requirements and test methods for mechanical weighing devices Ingestion-build-251241 The fourth group of threeThis European Standard specifies requirements and test methods for mechanical weighing devices for continuous monitoring of containers of CO2 , Inert Gas or Halocarbon Gas Fire Extinguishing Installations. This European Standard does not cover weighing devices for non transportable containers which are filled and refilled on site, e. g. CO2 low pressure containers.
