适用范围：This European Standard gives guidelines for background information and 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 air. It is concerned with apparatus whose primary purpose is to indicate the presence and concentration of a toxic gas or vapour to provide a rapid indication or warning of the presence of a toxic hazard within a time of response as specified in accordance with EN 45544-2 and EN 45544-3. It applies to: - personal, portable, transportable and fixed apparatus; - apparatus where the presence of a gas or vapour causes an automatically generated electrical signal; - apparatus intended to provide an indication, alarm and/or other output function, whose purpose is to give a warning of potential toxic hazard and in some cases to initiate automatic or manual protective actions. This European Standard is not intended, but can provide useful information, for the following: - apparatus used for the measurement of oxygen deficiency which can affect human health; - apparatus used for the measurement of combustible gases and vapours or oxygen related to the risk of explosion (see EN 50073); - apparatus of laboratory or scientific type used only for analysis or measurement purposes; - apparatus used only for process control applications; - apparatus used for underground mining applications; - apparatus used in the domestic environment; - apparatus used for environmental air pollution monitoring; - open path apparatus not used for point measurement.
