Overview
prEN 13142 (CEN) defines the required and optional performance characteristics for components and products used in residential ventilation systems. Its purpose is to ensure that manufacturers, designers and regulators can specify, test and compare ventilation components so that a complete system can deliver the intended comfort (temperature, air velocity, humidity), hygiene and acoustic conditions in dwellings. The document also provides a classification and codification scheme for balanced (mechanical supply and exhaust) ventilation units and an informative national annex for member states to define valid parameters.
Key topics and requirements
- Scope and exclusions: Applies to components/products for residential ventilation and to balanced ventilation units (referencing EN 13141‑7 and EN 13141‑8). It explicitly does not apply to items such as filters, fire dampers, ducts, control devices, sound attenuators, or to certain regulatory requirements (e.g., Low Voltage, EMC, corrosion or snow penetration).
- Performance characteristics: Specifies which characteristics shall be determined and presented (mandatory or optional) and how they relate to relevant test methods. Categories include:
- Aerodynamic characteristics (pressure drop, flow performance)
- Acoustic characteristics (radiated and in-duct noise)
- Air diffusion and terminal device behaviour
- Thermal characteristics and heat recovery performance (for mechanical balanced units)
- Electrical power and energy metrics (specific power input, standby/operating power)

Introduction
A ventilation system is the combination of all the components/products required to provide ventilation. These
components/products interact to achieve a renewal of the air in a dwelling.
It is important to consider each product not only individually but also as part of the whole system: for example from
the outdoor canopy of an externally mounted air transfer device to the roof outlet terminal at the end of an exhaust
duct. To enable good design it is essential that certain performance characteristics for each product are available in
a simple and comparable form.
1 Scope
This European Standard specifies and classifies the component/product performance characteristics which may be
necessary for the design and dimensioning of residential ventilation systems to provide the predetermined comfort
conditions of temperature, air velocity, humidity, hygiene and sound in the occupied zone.
It defines those performance characteristics (mandatory or optional) which shall be determined and measured and
presented according to relevant test methods. It will provide a classification scheme which lead to a full definition of
product properties based on European test methods described in various EN standards and gives an overview of
the Test Standards in various CEN TC´s. Distinction between mandatory and optional requirement is left to each
national regulations. This standard gives an informative national annex in which the member states define the valid
parameters.
The codification part in Clause 8 and the classification part in Clause 9 apply to the following products:
mechanical supply and exhaust unit according to EN 13141-7 and EN 13141-8.
This standard does not apply to other products such as filters, fire dampers, ducts, control devices,
sound attenuators, which may also be incorporated in residential ventilation.
This standard does not cover requirements raised by European directives, for example: Low voltage directive,
EMC directive and other requirements such as corrosion, resistance and snow penetration.
