Electronic portable and transportable apparatus designed to detect and measure carbon dioxide and/or carbon monoxide in indoor ambient air - Requirements and test methods
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.

4.1 Construction
4.1.1 General
All parts of the apparatus, including the sensors and probe, shall be constructed of materials that
will not be affected by vapours and gases or chemical substances typically found in the environment
in which it is intended to be used [see 4.2.2 c)].
The apparatus shall conform to IP40, in accordance with EN 60529:1991, Clauses 12 and 14.
Adjustments that might affect the performance of the apparatus shall be suitably protected against
unauthorized changes, such as through the use of passwords, tamper-evident seals or special
tools.
4.1.2 Power supplies
Apparatus which derives its power from internal batteries may give a visual warning before the
battery capacity falls to a point where either the apparatus sensitivity or the stated display accuracy
falls outside the requirements. When this point is actually reached, a clear indication shall be given
to alert the user and the display shall switch out of normal operational mode.
Apparatus provided with the means of connection to the mains supply shall conform to relevant EN
standards.

NOTE This area is covered by various statutory regulations.
4.1.3 Indicators
4.1.3.1 Indicators shall be provided to show:
a) measured parameter, values and units of measurement;
b) low battery warning for battery-powered apparatus;
c) for aspirated apparatus with an integrated flow indicator, a warning when a blockage occurs
(see 5.3.14);
d) mode of operation or apparatus status (e.g. warm-up and measurement);
e) when values lie outside the indicating range.
All values shall be indicated on a display with characters not less than 8 mm high, unless adequate
provision is made for enhancing the legibility (e.g. backlighting), in which case the minimum
character height shall be 4 mm.
For each separate parameter measured the apparatus shall display the value, the physical unit and
parameter description. For a combination of parameters the display may switch automatically from
one indication to another. If the display switches between information of simultaneous parameters it
shall be clear and understandable. Displayed measured values shall be refreshed at intervals no
greater than 3 s. If the apparatus is equipped with seven-segment displays it shall have a device or
self testing function for checking the displays.
4.1.3.2 For aspirated apparatus, a means shall be provided to recognise and/or indicate the
working mode of the pump (or a blockage of the gas path) by, for example:
• audible warning;
• visual indication; or
• flow measurement.
4.1.4 Range, resolution, accuracy and response time
4.1.4.1 Table 1 lists the different parameters covered by this European Standard. For each
parameter given it specifies the:
• minimum indication range;
• maximum display resolution;
• accuracy of the apparatus;
• maximum response time.
4.1.4.2 The indication ranges are the minimum ranges for the apparatus. Higher ranges are
allowed, but will not change the values for accuracy, resolution or response time.
