Fire resistance tests for non-loadbearing elements - Part 5: Air transfer grilles

Edition date: 2026-07-22
In Force
Available languages: English
Summary: 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 document is applicable to 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 (see Annex A). This document evaluates the behaviour of the air transfer grille when exposed to the heating 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 determination of the rate of leakage of smoke at ambient temperature or at 200 °C as an optional requirement for ATG with declared smoke control is specified in EN 1634 3. This document is not applicable to the determination of 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 document is not applicable to the determination of the fire resistance of a fire damper or a fire barrier connected to a duct one or both sides, as 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 document is not applicable to the determination of 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.

Le présent document spécifie une méthode permettant de déterminer la résistance au feu des grilles de transfert. Elle s’applique aux grilles de transfert 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 peut être verticale ou horizontale. Le mécanisme de fermeture de la grille de transfert peut être dû à la dilatation du matériau et/ou à un dispositif de fermeture mécanique ou électrique. Le présent document est applicable pour les grilles de transfert résistantes au feu ou résistantes au feu et étanches à la fumée. Une configuration d’essai supplémentaire est valable pour les grilles de transfert résistantes au feu ou résistantes au feu et étanches à la fumée pour les applications dans lesquelles il y a risque de contact avec des flammes au démarrage de l’essai lorsque l’échantillon est en état "ouvert" (voir Annexe A). Le présent document évalue le comportement de la grille de transfert lorsqu’elle est exposée à la courbe de chaleur décrite dans l’EN 1363 1 et à la pression normale décrite dans l’EN 1363 1. Cet essai n’a pas pour but de fournir des informations quantitatives sur le taux de fuite de la fumée et/ou des gaz chauds, ni sur la transmission ou la génération de fumées en cas d’incendie. Ces phénomènes doivent seulement figurer dans la description du comportement général des éléments d’essai pendant l’essai. La détermination du taux de fuite de la fumée à la température ambiante ou à 200 °C, qui est une exigence facultative pour les grilles de transfert déclarées étanches à la fumée est spécifiée dans l’EN 1634 3. Le présent document n’est pas applicable à la détermination de la résistance au feu des grilles de transfert utilisées dans des conduits car ces grilles sont considérées comme des éléments de séparation. La méthode d’essai des grilles de transfert utilisées dans des conduits est décrite dans les normes correspondantes se rapportant aux conduits. Le présent document n’est pas applicable à la détermination de la résistance au feu des clapets ou barrières résistants au feu raccordés à un conduit d’un côté ou des deux côtés car ces grilles sont soumises à l’essai en tant qu’éléments de séparation. Les clapets résistants au feu sont soumis à l’essai conformément à l’EN 1366 2. Les barrières résistantes au feu non mécaniques sont soumises à l’essai conformément à l’EN 1366 12. Le présent document n’est pas applicable à la détermination de la résistance au feu des grilles de transfert dans les portes, fermetures et fenêtres coupe-feu telles que spécifiées dans l’EN 1634 1 et l’EN 1364 2, car la déformation de ces éléments en cas d’incendie est différente de celle 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 le présent document sont des valeurs nominales, sauf spécification contraire.

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. Dieses Dokument ist für feuerwiderstandsfähige Lüftungsbausteine sowie für Lüftungsbausteine mit Feuerwiderstands- und Rauchschutzeigenschaften anwendbar. 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 (siehe Anhang A). In diesem Dokument wird das Verhalten von Lüftungsbausteinen bei Beanspruchung durch die Aufheizkurve 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 Bestimmung der Leckrate von Rauch bei Umgebungstemperatur bzw. bei 200 °C als optionale Anforderung für Lüftungsbausteine mit erklärten Rauchschutzeigenschaften ist in EN 1634 3 festgelegt. Dieses Dokument ist nicht für die Bestimmung des Feuerwiderstands von Lüftungsbausteinen anwendbar, 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. Dieses Dokument ist nicht für die Bestimmung des Feuerwiderstandes von Brandschutzklappen oder Brandschutzverschlüssen anwendbar, 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. Dieses Dokument ist nicht für die Bestimmung des Feuerwiderstands von Lüftungsbausteinen in Brandschutztüren, Abschlüssen und zu öffnenden Fenstern nach EN 1634 1 bzw. EN 1364 2 anwendbar, 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.
