In addition to a number of editorial revisions, the following main changes have been made with respect
to EN 13141-4:2011:
— the scope has been changed, and concerns now all unidirectional ventilation units (ducted or non-
ducted units, supply or exhaust units), excluding cowls with fans (see EN 13141-5);
— the terms and definitions have been updated in accordance with the parameters used in the
document;
— performance testing of aerodynamic characteristics clause includes new testing of external leakages;
— description of the connection box has been moved in a normative annex;
— determination of the maximum and reference air flow has been added;
— assessment of part load energy efficiency has been moved in an informative annex;
— tests of air flow sensitivity and indoor/outdoor airtightness have been added;
— in the energy part, the characterization of SPI has been added;
— the whole acoustic clause has been reorganized and references to acoustic standard updated;
— testing of noise radiated by the casing for ducted units has been added;
— testing of radiated sound power in the indoor or outdoor space and the airborne sound insulation of
non-ducted units have been added;
— the safety clause has been deleted;
— a new clause dealing with all test results has been created.
