Overview
This part of the 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. The primary purpose of such apparatus is to measure the concentration of a toxic gas or vapour in order to provide an exposure measurement and/or detection and warning of its presence. This European Standard is applicable to apparatus whose primary purpose is to provide an indication, alarm and/or other output function to give a warning of the presence of a toxic gas or vapour in the atmosphere and in some cases to initiate automatic or manual protective actions. It is applicable to apparatus in which the sensor automatically generates an electrical signal when gas is present. The responsible committee is DKE/UK 966.1 "Mess- und Warngeräte für gefährliche Gase" ("Measurement and warning devices for dangerous gases") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
