In comparison to EN 13141-4:2011, the title and the scope are modified. These
modifications are due to the new structure of EN 13141 series (see document
CEN/TC 156/WG 2 N 791).
This European Standard specifies aerodynamic, acoustic and electrical power performance test methods for
unidirectional ventilation units used in residential ventilation systems.
This document is applicable to ventilation units:
— installed on a wall or in a window without any duct, A category;
— installed in the upstream of a duct, B category;
— installed in the downstream of a duct, C category;
— installed in a duct, or with duct connection upstream and downstream, D category;
— with one or several inlets/outlets;
— installed in a system with a heat pump for domestic hot water or water for cooling or heating;
— which can be used for supply or exhaust.
This document does not apply to:
— fan assisted cowls which are tested according to EN 13141-5;
— mechanical supply and exhaust units which are tested according to prEN 13141-7 or prEN 13141-8
