This document specifies the laboratory test methods and test requirements for the testing of aerodynamic, thermal, acoustic and the electrical performance characteristics of non-ducted mechanical supply and exhaust residential ventilation units used in single dwellings. The purpose of this document is not to consider the quality of ventilation but to test the performance of the equipment. In general, a ventilation unit contains: - fans for mechanical supply and exhaust; - air filters; - air-to-air heat exchanger for heat and possibly humidity recovery; - control system; - inlet and outlet grilles. Such equipment can be provided in more than one assembly, the separate assemblies of which are designed to be used together. Such equipment can contain alternating heat exchangers which provide separate supply and exhaust air flows. In certain cases, i.e. alternating ventilation unit, it may be declared that the equipment can be installed in such a way that it serves more than one room. For the purpose of this document, these products are assessed in a single room. This document does not deal with ducted units which are covered by prEN 13141-7 or units with heat pumps. Safety requirements are given in EN 60335-2-40 and EN 60335-2-80.
