Fire resistance tests for non-loadbearing elements - Part 4: Curtain walling - Part configuration

This document specifies a method for determining the fire resistance of parts of curtain walling and of the perimeter seal. It examines the fire resistance to internal and external fire exposure of:
-   the spandrel panel, i.e. downstand, upstand or a combination thereof;
-   the perimeter seal;
-   the fixing of the framing system (anchoring) used to attach the curtain walling to the floor element;
-   combinations thereof.
NOTE 1   This document does not test fire spread that can be caused through cavities in the test specimen, i.e., inside of the mullions (see note to 9.1.2.3.3).
Results from tests according to this document form the basis for classification of curtain walling type A (see 3.3 for definition).
For curtain walling type B (see 3.4 for definition) results can be used to determine fire resistance of parts of a curtain walling to increase the field of application when previously tested to EN 1364-3. For intended classification EW and for corner/faceted specimens EN 1364-3 can be used.
This document does not cover double skin façades, over-cladding systems and ventilated façade systems on external walls. It does not deal with the reaction to fire behaviour of curtain walling.
This document is intended to be read in conjunction with EN 1363-1 and EN 1363-2 as well as EN 1364-3 for curtain walling type B.
As per the type of curtain walling covered by this document, these are the ones included in EN 13119.
NOTE 2   Annex A gives informative guidance on the principles of testing parts of curtain walling and the test method.
NOTE 3   When tests are made to examine single elements (e.g. perimeter seal), those elements are to be installed as part of a curtain walling system.

Feuerwiderstandsprüfungen für nichttragende Bauteile - Teil 4: Vorhangfassaden - Teilausführung

Dieses Dokument legt ein Verfahren zur Bestimmung der Feuerwiderstandsdauer von Teilen der Vorhangfassade und der Rand-Dichtung fest. Es untersucht den Feuerwiderstand der folgenden Elemente bei Brandbeanspruchung von innen und von außen:
   Brüstungspaneel, d. h. Schürze, aufgeständerte Brüstung oder eine Kombination daraus;
   Rand-Dichtung;
   Befestigung des Rahmensystems (Verankerung) zur Anbringung der Vorhangfassade am Deckenelement;
   Kombinationen dieser Elemente.
ANMERKUNG 1   Dieses Dokument prüft nicht die Ausbreitung von Feuer, die durch Hohlräume im Probekörper verursacht werden kann, d. h. innerhalb der Pfosten (siehe Anmerkung zu 9.1.2.3.3).
Die Ergebnisse der Prüfungen nach diesem Dokument bilden die Grundlage für die Klassifizierung von Vorhangfassaden vom Typ A (siehe 3.3 für die Definition).
Für Vorhangfassaden vom Typ B (siehe 3.4 für die Definition) können die Ergebnisse zur Bestimmung des Feuerwiderstands von Teilen der Vorhangfassade angewendet werden, um den Anwendungsbereich zu erweitern, sofern bereits Prüfungen nach EN 1364 3 durchgeführt wurden. Bei vorgesehener Klassifizierung EW sowie bei Probekörpern mit Ecken/facettierten Probekörpern kann EN 1364 3 angewendet werden.
Dieses Dokument deckt keine Doppelfassaden, Fassadenbekleidungssysteme und hinterlüftete Fassadensysteme an Außenwänden ab. Sie behandelt nicht das Brandverhalten von Vorhangfassaden.
Dieses Dokument ist dafür vorgesehen, zusammen mit EN 1363 1 und EN 1363 2 sowie EN 1364 3 für Vorhangfassaden vom Typ B angewendet zu werden.
Als der in diesem Dokument behandelten Art von Vorhangfassade entsprechend sind sie in EN 13119 enthalten.
ANMERKUNG 2   Anhang A enthält informative Hinweise zu den Grundsätzen der Prüfung von Teilen von Vorhangfassaden und zum Prüfverfahren.
ANMERKUNG 3   Wenn Prüfungen durchgeführt werden, um einzelne Elemente zu untersuchen (z. B. Rand-Dichtungen), müssen diese Elemente als Teil eines Vorhangfassadensystems installiert sein.

Essais de résistance au feu des éléments non-porteurs - Partie 4 : Murs rideaux - Configuration partielle

Le présent document spécifie une méthode permettant de déterminer la résistance au feu de parties de mur rideau et de l'étanchéité périphérique. Il étudie la résistance au feu à l'exposition intérieure et externe :
—   du panneau d'allège, c'est-à-dire panneau d'allège suspendu, en appui ou combinaison des deux ;
—   de l'étanchéité périphérique ;
—   de la fixation du système d'ossature (ancrage) utilisée pour attacher le mur rideau à l'élément de plancher ;
—   de combinaisons de ceux-ci.
NOTE 1   Le présent document n'éprouve pas la propagation du feu qui peut être provoquée par des cavités dans l'élément d'essai, c'est-à-dire à l'intérieur des meneaux (voir la note du 9.1.2.3.3).
Les résultats des essais réalisés conformément au présent document servent de base au classement d'un mur rideau de type A (voir définition en 3.3).
Pour un mur rideau de type B (voir définition en 3.4), les résultats peuvent être utilisés pour déterminer la résistance au feu de parties du mur rideau afin d'étendre le champ d'application, lorsqu'il a été préalablement soumis à essai conformément à l'EN 1364 3. Lorsqu'un classement EW est prévu et pour les éléments d'essai à angles/facettes, l'EN 1364 3 peut être utilisée.
Le présent document ne couvre pas les façades double peau, les systèmes de bardage et les systèmes de façades ventilées sur des murs extérieurs. Il ne traite pas du comportement au feu des murs rideaux.
Le présent document est destiné à être lu conjointement à l’EN 1363 1 et à l'EN 1363 2 ainsi qu'à l'EN 1364 3 pour un mur rideau de type B.
Selon le type de mur rideau couvert par le présent document, ceux-ci sont ceux figurant dans l'EN 13119.
NOTE 2   L'Annexe A donne des lignes directrices concernant les principes et la méthode d’essai de parties de mur rideau.
NOTE 3   Lorsque des essais sont effectués pour examiner des éléments simples (par exemple l'étanchéité périphérique), ces éléments doivent être installés comme une partie d'un système de mur rideau.

European foreword
This document (prEN 1364-4:2025) 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 will supersede EN 1364-4:2014.
— Existing definitions updated and new definitions added, in order to avoid misleading interpretation
of the standard;
— Extension of test specimen to bespoke curtain walling;
— Extension of the test specimen configuration (see 6.3) also to unitized curtain walling;
— General revision of Clause 13 “Field of direct application of test results” and of Annex B “test
configurations”;
— Annex D “Field of direct application of test results for unitised construction” deleted.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
Introduction
WARNING — The attention of all persons concerned with managing and carrying out this fire resistance
test 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 developed 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.
WARNING — An assessment of all potential hazards and risks to health should be made and safety
precautions should be identified and provided. Written safety instructions should be issued. Appropriate
training should be given to relevant personnel. Laboratory personnel should ensure that they follow
written safety instructions at all times.
