Ventilation for buildings - Components/products for residential ventilation - Required and optional performance characteristics
This European standard 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 A and the classification part in Clause 4 apply to the following products:
- unidirectional mechanical supply and exhaust residential ventilation units according to prEN 13141 4, prEN 13141 6 and prEN 13141 11;
- ducted mechanical bidirectional residential ventilation units according to prEN 13141 7;
- non-ducted mechanical bidirectional residential ventilation units according to prEN 13141 8.
This European standard 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 European standard specifies in Annex ZA the requirements of EU 1253/2014 and EU 1254/2014 for residential ventilation units below 1 000 m3/h air volume flow.
This European standard does not cover requirements raised by European Directives (e.g. low voltage directive, EMC directive) and other requirements such as corrosion, fire resistance and snow penetration.
Lüftung von Gebäuden - Bauteile/Produkte für die Lüftung von Wohnungen - Geforderte und frei wählbare Leistungskenngrössen
Dieses Dokument legt die Leistungskenngrößen von Bauteilen bzw. Produkten fest, die für die Auslegung, Einstufung und Dimensionierung, Markteinführung von Produkten und Anlagen für die Wohnungslüftung erforderlich sein können, um die einzuhaltenden Leistungsanforderungen, Behaglichkeitsbedingungen bezüglich Temperatur, Luftgeschwindigkeit, Luftfeuchte, Hygiene und Schall im Aufenthaltsbereich zu erreichen, und klassifiziert diese Leistungskenngrößen.
Das Dokument definiert diejenigen Leistungskenngrößen (verbindlich vorgeschrieben oder frei wählbar), die nach den entsprechenden Prüfverfahren bestimmt, gemessen und dargestell werden müssen. Es bietet ein Klassifizierungsschema, das eine vollständige Definition der Produkteigenschaften auf der Grundlage von in verschiedenen EN-Normen beschriebenen Prüfverfahren ermöglicht, und liefert einen Überblick über die Prüfnormen. Die Entscheidung darüber, welche Anforderungen verbindlich vorgeschrieben und welche frei wählbar sind, ist den jeweiligen Europäischen und nationalen Vorschriften überlassen.
Der Kodierungsteil in Anhang B und der Klassifizierungsteil in Abschnitt 8 gelten für die folgenden Produkte:
— unidirektionale ventilatorgestützte Zu- und Abluft-Lüftungsgeräte für Wohnungen nach EN 13141 4:2021, EN 13141 6:2014 und EN 13141 11;
— ventilatorgestützte, bidirektionale Lüftungsgeräte mit Kanalanschluss für Wohnungen nach EN 13141 7:2021;
— ventilatorgestützte, bidirektionale Lüftungsgeräte ohne Kanalanschluss für Wohnungen nach prEN 13141 8:2020.
Dieses Dokument gilt nicht für weitere Produkte wie Filter, Brandschutzklappen, Luftleitungen/Kanäle, Steuer- und Regelungseinrichtungen und Schalldämpfer, die ebenfalls Bestandteil einer Wohnungslüftung sein können.
Dieses Dokument legt in Anhang ZA und Anhang ZB die Anforderungen der EU 1253/2014 und der EU 1254/2014 für Wohnungs-Lüftungsgeräte unter 1 000 m3/h Luftvolumenstrom fest.
Dieses Dokument deckt keine Anforderungen Europäischer Richtlinien (z. B. der Niederspannungsrichtlinie und der EMV-Richtlinie), ebenso wie weitere Anforderungen, beispielsweise hinsichtlich der Korrosion, des Brandverhaltens und des Widerstands gegen das Eindringen von Schnee, ab.
Ventilation des bâtiments - Composants/produits pour la ventilation des logements - Caractéristiques de performances exigées et optionnelles
Le présent document spécifie et classe les caractéristiques de performance des composants/produits qui peuvent être nécessaires pour la conception, la classification et le dimensionnement, la mise à disposition sur le marché des produits et systèmes de ventilation résidentielle afin de fournir les performances, les conditions de confort en température, la vitesse d’air, l’humidité, l’hygiène et le bruit prédéterminés dans la zone occupée.
Il définit les caractéristiques de performance (obligatoires ou optionnelles) qui doivent être déterminées, mesurées et présentées selon des méthodes d'essais appropriées. Il fournit un schéma de classification qui conduit à une définition complète des propriétés du produit, basée sur des méthodes d’essais décrites dans diverses normes EN et donne une vue d’ensemble des normes d’essais. La distinction entre les prescriptions obligatoires et optionnelles est laissée à chaque réglementation européenne et nationale.
La partie codification en Annexe B et la partie classification à l’Article 8 s’appliquent aux produits suivants :
- unités de ventilation mécanique unidirectionnelle résidentielle par insufflation et par extraction selon l'EN 13141-4:2021, l’EN 13141-6:2014 et l’EN 13141-11 ;
- centrales double flux résidentielle raccordées selon l'EN 13141-7:2021 ;

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
