This European Standard specifies aerodynamic, acoustic and electrical power performance test methods for fans used in residential ventilation. These methods primarily concern:
- ventilation fans installed on a wall or in a window without any duct;
- ventilation fans installed in the downstream of a duct;
- ventilation fans installed in the upstream of a duct;
- ventilation fans installed in a duct;
- encased ventilation fans having several inlets.
For acoustic performance testing one of the following methods is used:
- in-duct method;
- reverberant room method;
- enveloping surface method.
