Introduction
A combination of components and/or products is 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.
This document defines also a classification for balanced ventilation units which may be used for the
determination of minimum and optional product characteristic in national building regulations and
standards.
The structure of this document is based on the type of products that are given in Table 1 that specifies
the type of information for them.

This document does not apply to other products such as filters, fire dampers, ducts, control devices and
sound attenuators, which may also be incorporated in residential ventilation.
This document specifies in Annex ZA and Annex ZB the requirements of EU 1253/2014 and
EU 1254/2014 for residential ventilation units below 1 000 m /h air volume flow.
This document does not cover requirements raised by European Directives (e.g. low voltage directive,

service. A product shall therefore be tested as a complete assembly with all necessary components that
affect performance.
Accessories are sometimes available for a product as an option. Where accessories could affect
performance, the product shall be tested both with and without those accessories.

Introduction
A combination of components and/or products is 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.
This document defines also a classification for balanced ventilation units which may be used for the
determination of minimum and optional product characteristic in national building regulations and
standards.
The structure of this document is based on the type of products that are given in Table 1 that specifies
the type of information for them.

EN 13142:2013 has been revised to include new requirements according to Ecodesign requirements for
ventilation units given in EU Commission Delegated Regulation No EU 1253/2014 and
No EU 1254/2014.
1 Scope
This document specifies and classifies the component/product performance characteristics, which may
be necessary for the design, rating and dimensioning, placing on the market of residential ventilation
products and systems to provide the predetermined performance, 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,
measured and presented according to relevant test methods. It provides a classification scheme, which
leads to a full definition of product properties based on test methods described in various EN Standards,
and gives an overview of the test standards. Distinction between mandatory and optional requirement is
left to each European and national regulations.
The codification part in Annex B and the classification part in Clause 8 apply to the following products:
— unidirectional mechanical supply and exhaust residential ventilation units according to
EN 13141-4:2021, EN 13141-6:2014 and EN 13141-11;
— ducted mechanical bidirectional residential ventilation units according to EN 13141-7:2021;
— non-ducted mechanical bidirectional residential ventilation units according to prEN 13141-8:2020.
This document does not apply to other products such as filters, fire dampers, ducts, control devices and
sound attenuators, which may also be incorporated in residential ventilation.
This document specifies in Annex ZA and Annex ZB the requirements of EU 1253/2014 and
EU 1254/2014 for residential ventilation units below 1 000 m /h air volume flow.
This document does not cover requirements raised by European Directives (e.g. low voltage directive,
EMC directive) and other requirements such as corrosion, reaction to fire and snow penetration.

5 Performance characteristics for residential ventilation components/products
5.1 General
5.1.1 Generality for tests
The results of product performance tests reflect the performance that is achieved by the product in
service. A product shall therefore be tested as a complete assembly with all necessary components that
affect performance.
Accessories are sometimes available for a product as an option. Where accessories could affect
performance, the product shall be tested both with and without those accessories.
If any insect screen, filter or similar device is intended to be fitted in the product, then it shall be in
position when the produ
