Introduction
This European Standard specifies methods for the performance testing of components used in residential
ventilation systems to establish the main characteristics as identified in EN 13142.
Part 1 and Part 2 relate respectively to the externally/internally mounted air transfer devices and the exhaust/supply
air terminal devices, which are used in the residential ventilation.
Part 3 considers performance testing of range hoods for residential use, and is based on an IEC standard.
Part 4 consists in some special measurement conditions for fans to be used in the residential systems, when
applying the general ISO methods (as ISO 5801).
Part 5 gives test methods for cowls and other roof outlets.
Part 6 gives test methods for exhaust ventilation system packages used in a single dwelling.
Part 7 gives test methods for supply and exhaust ventilation unit used in a single dwelling.
Part 8 gives test methods for un-ducted supply and exhaust ventilation unit used in a single room.
The standard incorporates many references to other European and International Standards, especially on
characteristics other than the aerodynamic characteristics, for instance on acoustic characteristics.
In most cases some additional tests or some additional conditions are given for the specific use in residential
ventilation systems.
The standard can be used for the following applications:
 laboratory testing;
 attestation purposes.

1 Scope
This European Standard specifies the laboratory test methods and test requirements for the testing of
aerodynamic, thermal and acoustic performance, and the electrical power of a un-ducted mechanical supply and
exhaust ventilation unit used in a single room.
In general, such a unit contains:
 supply and exhaust air fans;
 air filters;
 air to air heat exchanger for exhaust air heat recovery;
 control system.
Such equipment can be provided in more than one assembly, the separate assemblies of which are designed to be
used together.
This European Standard does not deal with ducted units or units with heat pumps.
Safety requirements are given in EN 60335-2-80.
