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 (CO2) 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 CO2 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 CO2 concentrations in commercial laundry and kitchen environments, assessing the safe
operation of appliances installed in compartments.
NOTE 2 When this apparatus is used in industrial premises national regulations may apply.
