Defines aerodynamic acoustic and electrical power performance test measurements for: - un-ducted continuous supply ventilation units in a single room; - ducted continuous supply ventilation units in a single room; - un-ducted supply air ventilation units in a single room; - ducted supply air ventilation units in a single room; and - centralised unit for whole dwelling; used in residential ventilation.

1.1 This European Standard specifies aerodynamic, acoustic and electrical power performance test measurements for

• un-ducted continuous supply ventilation units in a single room;

• ducted continuous supply ventilation units in a single room;

• un-ducted supply air ventilation units in a single room;

• ducted supply air ventilation units in a single room;

• centralised unit for whole dwelling;

used in residential ventilation.

In general such units contain the following elements:

• fan;

• air filter;

• control system.

1.2 This European Standard does not cover the following:

• grilles, air delivery or air supply devices when the unit is ducted;

• sound attenuation;

• any heating devices or pre-heaters.

1.3 Safety requirements are given in EN 60335-2-80:2003 and its A2:2009 [2].
