Fire resistance tests for non-loadbearing elements - Part 6: Open-state cavity barriers
This test method specifies methods for determining the fire resistance of cavity barriers and is to be used in conjunction with EN 1363-1.
This document is applicable to non-loadbearing vertically or horizontally oriented closed and open cavity barriers, which are used to provide fire separation to uncompartmented or ventilated spaces. Cavity barriers are designed to provide fire separating performance and the test method is therefore based on the standard room fire exposure in EN 1363-1. Open cavity barrier specimens are installed for test in one of two ways to simulate either normal or sudden exposure to fire in use.
Ventilating cavity barriers in facades, where the fire exposure comes as a result of a breaking window and allowing a developed fire to come into contact with the façade, shall be tested as prescribed in Annex D.
This document is not applicable to cavity barriers containing penetration seals, which shall be tested to EN 1366-3.
Feuerwiderstandsprüfungen für nichttragende Bauteile - Teil 6: Hohlraum-Brandsperren
Dieses Prüfverfahren legt Verfahren zur Bestimmung des Feuerwiderstands von Hohlraum-Brandsperren fest und ist in Kombination mit EN 1363-1 anzuwenden.
Dieses Dokument ist anwendbar auf nichttragende vertikal oder horizontal ausgerichtete, geschlossene und offene Hohlraum-Brandsperren, die als Brandsperren in nicht unterteilten oder belüfteten Räumen zum Einsatz kommen. Hohlraum-Brandsperren sind darauf ausgelegt, den Brandübertritt zu verhindern, und das Prüfverfahren basiert daher auf den genormten Beflammungsbedingungen für Räume nach EN 1363-1. Es werden Probekörper von offenen Hohlraum-Brandsperren zur Prüfung in einer von zwei möglichen Konfigurationen installiert, um entweder eine langsame oder eine plötzliche Brandeinwirkung im Betrieb zu simulieren.
Hinterlüftete Hohlraumabschlüsse in Fassaden, bei denen die Brandeinwirkung durch ein zerbrechendes Fenster entsteht und ein sich entwickelndes Feuer mit der Fassade in Berührung kommen kann, müssen nach Anhang D geprüft werden.
Dieses Dokument gilt nicht für Hohlraum-Brandsperren mit Abschottungen, die nach EN 1366-3 geprüft werden müssen.
Essais de résistance au feu des éléments non porteurs - Partie 6 : Dispositifs de recoupement de lame d’air
La présente méthode d’essai spécifie une méthode permettant de déterminer la résistance au feu des dispositifs de recoupement de lame d’air et doit être utilisée conjointement avec l’EN 1363-1.
Le présent document s’applique aux dispositifs de recoupement de lame d’air non porteurs, fermés et ouverts, orientés verticalement ou horizontalement, qui sont utilisés pour assurer le cloisonnement coupe-feu d’espaces non compartimentés ou ventilés. Les dispositifs de recoupement de lame d’air sont conçus pour offrir des performances de cloisonnement coupe-feu et la méthode d’essai est donc fondée sur l’exposition au feu d’une pièce normalisée selon l’EN 1363-1. Les éléments d’essai de dispositif de recoupement de lame d’air ouvert sont installés en vue de l’essai de manière à simuler soit une exposition normale, soit une exposition soudaine au feu en service.
La ventilation des dispositifs de recoupement de lame d’air dans les façades, où l’exposition au feu résultant d’une fenêtre cassée et permettant à un incendie développé d’entrer en contact avec la façade, doit être soumise à essai tel que prescrit dans l’Annexe D.
La présente norme ne s’applique pas aux dispositifs de recoupement de lame d’air contenant des calfeutrements de trémies qui doivent être soumis à essai conformément à l’EN 1366-3.

Introduction
Cavity barriers are provided within buildings to restrict the spread of smoke and fire in concealed spaces.
Cavity barriers can be ‘closed’ e.g. in roof voids, under raised or hollow floors, between the inner and
outer layers of walls such as in timber framed construction; or they can be ‘open’ e.g. as used in ventilated
facade systems, roof eaves, rain screen cladding systems.
This document describes tests to measure the ability of a representative specimen of an open-state cavity
barrier to resist the spread of fire from one side to another. A representative sample of a cavity barrier is
exposed to a specified regime of heating and pressure. The performance of the test specimen is monitored
on the basis of criteria in EN 1363-1. The fire resistance of the tested construction is expressed as the
time for which the appropriate criteria have been satisfied.
The principles embodied in this method follow those embodied in EOTA TR31 the fire resistance test for
closed cavity barriers published in 2008. However, TR31 is not applicable to open-state cavity barriers
and consequently this method has had to be adapted to include these.
Testing of closed cavity barriers is not in the scope of this document. Test methods for closed cavity
barriers are covered by EN 1366-4. Testing of large-scale closed cavity barriers are covered by
EN 1364-1.
