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.

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.

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 131
