scope:
Specifies general requirements for construction and testing, and specifies the test methods that apply to personal, portable, transportable and fixed apparatus intended for the direct detection and direct concentration measurement of a toxic gas or vapour in workplace air. It applies to apparatus whose primary purpose is to indicate the presence of a toxic gas or vapour in the atmosphere with a view to providing an indication or warning of the presence of a toxic hazard within a time of response as specified in EN 45544-2 and EN 45544-3. Only apparatus in which the presence of the gas causes a change which is manifested as an automatically generated electrical signal will be considered as being within the scope of this standard. It is applicable to apparatus intended to provide an indication, alarm and/or other output function, the purpose of which is to give a warning of potential hazard and in some cases to initiate automatic or manual protective actions.
