EN 45544-1:1999 Workplace Atmospheres - Electrical Apparatus Used for the Direct Detection and Direct Concentration Measurement of Toxic Gases and Vapours - Part 1: General Requirements and Test Methods
This European Standard 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 European 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 toxic hazard and in some cases to initiate automatic or manual protective actions.
This European Standard does not apply to apparatus:
- used for the measurement of oxygen;
- used only in laboratories for analysis or measurement;
- used only for process measurement purposes;
- 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.
