1 Scope 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.
