1 Scope
This European Standard specifies requirements for the construction, testing and performance
of electronic portable and transportable apparatus for the detection and measurement of carbon dioxide (CO 2 ) and/or carbon monoxide (CO) in indoor ambient air , which includes air entering mechanical ventilation systems in domestic residential,
commercial and industrial premises and public buildings.
This European Standard includes indoor air quality apparatus with CO and CO 2 measuring capabilities.
This European Standard excludes:
• apparatus used in workplace atmospheres for the direct detection and direct concentration
measurement of toxic gases and vapours (i.e. conforming to EN 45544 series);
•
electronic portable combustion gas analysers (i.e. conforming to EN 50379 series);
• apparatus for the detection of carbon monoxide in domestic premises (i.e. conforming
to EN 50291 series).
NOTE 1 Examples of applications are monitoring indoor air quality, measuring CO and/or CO 2 concentrations in commercial laundry and kitchen environments, assessing the safe
operation of appliances installed in compartments.
