Fire resistance tests for non-loadbearing elements - Part 5: Air transfer grilles
This document specifies a method for determining the fire resistance of air transfer grilles (ATG).
It is applicable to air transfer grilles intended for installation in building components (typically walls, floors or ceilings). The orientation of the installation of the air transfer grille can be vertical or horizontal.
The closing mechanism of the air transfer grille can come from expansion of material and/or from any mechanical or electrical closing device.
This test method is valid for fire resistant or fire resistant and smoke control air transfer grilles.
An additional test configuration is valid for fire resistant or fire resistant and smoke control air transfer grilles in applications where flame impingement is a risk during open state from start of fire (Annex A).
This test method evaluates the behaviour of the air transfer grille when exposed to the standard fire curve described in EN 1363 1 and the standard pressure described in EN 1363 1. It is not the intention of this test to provide quantitative information on the rate of leakage of smoke and/or hot gases or on the transmission or generation of fumes under fire conditions. Such phenomena are only noted in describing the general behaviour of test specimens during the test.
The rate of leakage of smoke at ambient temperature or at 200 °C as an optional requirement for ATG with declared smoke control will be confirmed in accordance with EN 1634 3.
This test method is not valid for determining the fire resistance of air transfer grilles that are used in ducts because ATG are considered as separating elements. The test method for ATG, used in ducts is described in the corresponding duct standards.
This test method is not valid for determining the fire resistance of a fire damper or a fire barrier connected to a duct on either or both sides because an ATG is tested as a fire-separating element on its own. Fire dampers are tested according to EN 1366 2. Non-mechanical fire barriers are tested according to EN 1366 12.
This test method is not valid for determining the fire resistance of air transfer grilles in fire doors, shutters and openable windows as specified in EN 1634 1 and EN 1364 2, because the deformation of fire doors, shutters and openable windows in fire conditions differs from the deformation of flexible/rigid walls. Moreover, the location of thermocouples in the door standard is too specific to be handled in this document.
All values given in this document are nominal unless otherwise specified.
Feuerwiderstandsprüfungen für nichttragende Bauteile - Teil 5: Lüftungsbausteine
Dieses Dokument legt ein Prüfverfahren zur Bestimmung des Feuerwiderstands von Lüftungsbausteinen (LB) fest.
Es gilt für Lüftungsbausteine zum Einbau in Gebäudeteile (typischerweise Wände, Decken oder Unterdecken). Der Einbau der Lüftungsbausteine kann vertikal oder horizontal erfolgen.
Der Schließmechanismus der Lüftungsbausteine kann auf der Ausdehnung der Baustoffe und/oder auf jeglichen mechanischen oder elektrischen Schließvorrichtungen beruhen.
Das hier beschriebene Prüfverfahren gilt für feuerwiderstandsfähige Lüftungsbausteine sowie für Lüftungsbausteine mit Feuerwiderstands- und Rauchschutzeigenschaften.
Für feuerwiderstandsfähige Lüftungsbausteine bzw. für Lüftungsbausteine mit Feuerwiderstands- und Rauchschutzeigenschaften gilt eine zusätzliche Prüfkonfiguration für Anwendungsfälle, in denen die Gefahr der Flammenbeaufschlagung während des offenen Zustandes zu Beginn der Prüfung besteht (Anhang A).
Mit dem Prüfverfahren wird das Verhalten von Lüftungsbausteinen bei Beanspruchung durch die Norm-Brandkurve nach EN 1363 1 und den Normdruck nach EN 1363 1 bewertet. Diese Prüfung ist nicht dafür vorgesehen, quantitative Angaben zur Leckrate von Rauch und/oder heißen Gasen oder zur Übertragung oder Erzeugung von Rauch unter Brandbedingungen zu liefern. Derartige Phänomene werden lediglich im Zusammenhang mit der Beschreibung des allgemeinen Verhaltens der Probekörper während der Prüfung aufgezeichnet.
Die Leckrate von Rauch bei Umgebungstemperatur bzw. bei 200 °C als optionale Anforderung für Lüftungsbausteine mit erklärten Rauchschutzeigenschaften wird nach EN 1634 3 bestätigt.
Das hier beschriebene Prüfverfahren gilt nicht für die Bestimmung des Feuerwiderstands von Lüftungsbausteinen, die in Kanälen/Schächten eingesetzt werden, da Lüftungsbausteine als raumabschließende Bauteile betrachtet werden. Das Prüfverfahren für Lüftungsbausteine zur Anwendung in Kanälen/Schächten wird in den entsprechenden Normen zu den Kanälen/Schächten beschrieben.
Das Prüfverfahren gilt nicht für die Bestimmung des Feuerwiderstandes von Brandschutzklappen oder Brandschutzverschlüssen, die an einer Seite oder an beiden Seiten mit einem Kanal/Schacht verbunden sind, da Lüftungsbausteine separat als raumabschließende Elemente geprüft werden. Brandschutzklappen werden nach EN 1366 2 geprüft. Nichtmechanische Brandschutzverschlüsse für Lüftungsleitungen werden nach EN 1366 12 geprüft.
Das Prüfverfahren gilt nicht für die Bestimmung des Feuerwiderstands von Lüftungsbausteinen in Brandschutztüren, Abschlüssen und zu öffnenden Fenstern nach EN 1634 1 bzw. EN 1364 2, da die Verformung von Brandschutztüren, Abschlüssen und zu öffnenden Fenstern unter Brandbedingungen von der Verformung von Wänden in Leicht- bzw. Massivbauweise abweicht. Darüber hinaus sind die Angaben zur Anordnung der Thermoelemente in der türbezogenen Norm zu spezifisch, um im vorliegenden Dokument behandelt werden zu können.
Falls nichts anderes festgelegt ist, sind sämtliche in diesem Dokument angegebenen Werte Nennwerte.
Essais de résistance au feu des éléments non porteurs - Partie 5 : Grilles de transfert
Ce document spécifie une méthode pour déterminer la résistance au feu des grilles de transfert d'air (ATG).
Elle s'applique aux grilles de transfert d'air destinées à être installées dans des éléments de construction (généralement des murs, des planchers ou des plafonds). L'orientation de l'installation de la grille de transfert d'air peut être verticale ou horizontale.
Le mécanisme de fermeture de la grille de transfert d'air peut provenir de l'expansion du matériau et/ou de tout dispositif de fermeture mécanique ou électrique.
Cette méthode d'essai est valable pour les grilles de transfert d'air résistantes au feu ou résistantes au feu et au désenfumage.
Une configuration d'essai supplémentaire est valable pour les grilles de transfert d'air résistantes au feu ou résistantes au feu et de désenfumage dans les applications où il y a un risque de projection de flammes à l'état ouvert dès le début de l'incendie (annexe A).
Cette méthode d'essai évalue le comportement de la grille de transfert d'air lorsqu'elle est exposée à la courbe d'incendie standard décrite dans la norme EN 1363 1 et à la pression standard décrite dans la norme EN 1363 1. Cet essai n'a pas pour but de fournir des informations quantitatives sur le taux de fuite de fumée et/ou de gaz chauds ou sur la transmission ou la génération de fumées dans des conditions d'incendie. Ces phénomènes ne sont pris en compte que dans la description du comportement général des éprouvettes pendant l'essai.
Le taux de fuite des fumées à la température ambiante ou à 200 °C en tant qu'exigence facultative pour les ATG avec contrôle déclaré des fumées sera confirmé conformément à la norme EN 1634 3.
Cette méthode d'essai n'est pas valable pour déterminer la résistance au feu des grilles de transfert d'air utilisées dans les gaines, car les ATG sont considérées comme des éléments de séparation. La méthode d'essai pour les grilles de transfert d'air utilisées dans les gaines est décrite dans les normes correspondantes relatives aux gaines.
Cette méthode d'essai n'est pas valable pour déterminer la résistance au feu d'un clapet coupe-feu ou d'une barrière coupe-feu raccordé(e) à un conduit d'un côté ou des deux côtés, parce qu'un ATG est testé en tant qu'élément de séparation du feu à part entière. Les clapets coupe-feu sont testés conformément à la norme EN 1366 2 et les barrières coupe-feu non mécaniques conformément à la norme EN 1366 12.
Cette méthode d'essai n'est pas valable pour déterminer la résistance au feu des grilles de transfert d'air dans les portes coupe-feu, les volets et les fenêtres ouvrantes, comme spécifié dans les normes EN 1634 1 et EN 1364 2, car la déformation des portes coupe-feu, des volets et des fenêtres ouvrantes dans des conditions d'incendie diffère de la déformation des murs flexibles/rigides. En outre, l'emplacement des thermocouples dans la norme relative aux portes est trop spécifique pour être traité dans le présent document.
Toutes les valeurs indiquées dans ce document sont nominales, sauf indication contraire.

European foreword
This document (prEN 1364-5:2025) has been prepared by Technical Committee CEN/TC 127 “Fire safety
in buildings”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
EN 1364 ‘Fire resistance tests for non-loadbearing elements’ consists of the following parts:
— Part 1: Walls
— Part 2: Ceilings
— Part 3: Curtain walling - Full configuration (complete assembly)
— Part 4: Curtain walling - Part configuration
— Part 5: Air transfer grilles
— Part 6: Cavity Barriers
Introduction
The purpose of this test is to measure the ability of a representative specimen of an air transfer grille to
resist the spread of fire from one side to another.
A representative sample of the air transfer grille is exposed to a specified regime of heating and the
performance of the test specimen is monitored on the basis of criteria given in this document. Fire
resistance of the test specimen is expressed as the time for which the appropriate criteria have been
satisfied. The times so obtained are a measure of the adequacy of the construction in a fire but have no
direct relationship with the duration of a real fire.
CAUTION - The attention of all persons concerned with managing and carrying out this furnace testing is
drawn to the fact that fire testing can be hazardous and that there is a possibility that toxic and/or
harmful smoke and gases can be evolved during the test. Mechanical and operational hazards can also
arise during the construction of the test elements or structures, their testing and disposal of test residues.
An assessment of all potential hazards and risks to health needs to be made and safety precautions need
to be identified and provided. Written safety instructions need to be issued. Appropriate training needs
to be given to relevant personnel. Laboratory personnel need to ensure that they follow written safety
instructions at all times.
