Give feedback This European Standard gives guidance on the selection, installation, use and maintenance of electrical apparatus used for the direct detection and direct concentration measurement of toxic gases and vapours in workplace atmospheres. It is applicable to apparatus in which the sensor automatically generates an electrical signal when gas is present. This European Standard is not applicable, but may provide useful information, for apparatus — used for the measurement of oxygen, — used only in laboratories for analysis or measurement, — used only for process measurement purposes, — used in car parks or tunnels fixed apparatus only , — used in the domestic environment, — used in environmental air pollution monitoring, — used for the measurement of combustible gases and vapours related to the risk of explosion. It also does not apply to open-path line of sight area monitors.
