Fire resistance tests for non-loadbearing elements - Part 3: Curtain walling - Full configuration (complete assembly)

This European Standard specifies a method for determining the fire resistance of curtain walling full configuration.
This European Standard is used in conjunction with EN 1363 1.
NOTE   Annex B gives further information on the test method.
The test method is applicable to curtain walling type B (for definition see 3.4). The test is not appropriate for testing curtain walling type A (for definition see 3.3).
The fire resistance of curtain walling may be determined under internal or external exposure conditions. In the latter case the external fire exposure curve given in EN 1363 2 may be used, subject to deviating national regulations.
Tests on individual parts of a curtain walling (e.g. perimeter seal, infill panel or fixing of the framing system (anchoring) used to attach the curtain walling to the floor element) or systems with fire resistance requirements only to the spandrel area may be performed using EN 1364 4. For vertical linear gap seals, this part of the standard applies.
This European Standard 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 standard is intended to be read in conjunction with EN 1363 1 and EN 1363 2.

Feuerwiderstandsprüfungen für nichttragende Bauteile - Teil 3: Vorhangfassaden - Gesamtausführung

Diese Europäische Norm legt ein Verfahren zur Bestimmung der Feuerwiderstandsdauer von Vorhang-fassadensystemen — Gesamtausführung fest.
Diese Europäische Norm gilt zusammen mit EN 1363 1.
ANMERKUNG   Anhang B enthält weitere Informationen zum Prüfverfahren.
Das Prüfverfahren ist auf Vorhangfassaden vom Typ B anwendbar (für die Definition siehe 3.4). Das Verfahren ist nicht geeignet für die Prüfung von Vorhangfassaden vom Typ A (für die Definition siehe 3.3).
Die Feuerwiderstandsdauer von Vorhangfassaden darf bei Brandbeanspruchung von innen oder von außen ermittelt werden. Im letzteren Fall darf die Außenbrandkurve nach EN 1363 2 unter Berücksichtigung möglicherweise abweichender nationaler Regelungen eingesetzt werden.
Prüfungen an einzelnen Teilen einer Vorhangfassade (z. B. Rand-Dichtung, Ausfachung oder Befestigung des Rahmensystems (Verankerung) zum Befestigen der Vorhangfassade an den Deckenelementen) oder an Systemen, bei denen die Anforderungen an den Feuerwiderstand nur den Brüstungsbereich betreffen, dürfen unter Anwendung der EN 1364 4 durchgeführt werden. Für vertikale Anschlussfugenabdichtungen gilt der vorliegende Teil der Norm.
Die vorliegende Europäische Norm deckt keine Doppelfassaden, Fassadenbekleidungssysteme und hinterlüftete Fassadensysteme an Außenwänden ab. Sie behandelt nicht das Brandverhalten von Vorhang-fassaden.
Diese Norm ist dafür vorgesehen, zusammen mit EN 1363 1 und EN 1363 2 angewendet zu werden.

Essais de résistance au feu des éléments non-porteurs dans les bâtiments - Partie 3: Murs rideaux - Configuration en grandeur réelle (assemblage complet)

La présente Norme européenne prescrit une méthode de détermination de la résistance au feu des murs
rideaux (configuration en grandeur réelle).
La présente Norme européenne est utilisée conjointement avec l'EN 13636-1.
NOTE L'Annexe B donne des informations supplémentaires sur la méthode d'essai.
La méthode d'essai est applicable aux murs rideaux de type B (pour la définition, voir 3.4). L'essai n'est pas
approprié pour les murs rideaux de type A (pour la définition, voir 3.3).
La résistance au feu des murs rideaux peut être déterminée sous des conditions d'exposition au feu intérieur
ou extérieur. Dans ce dernier cas, on utilise la courbe d'exposition au feu extérieur donnée dans l'EN 1363-2,
sous réserve qu'il n'y ait pas de divergence avec les réglementations nationales.
Les essais sur les éléments individuels d'un mur rideau (par exemple, étanchéité périphérique, panneau de
remplissage, ou fixation du système d'ossature (ancrage) utilisée pour attacher le mur rideau à l'élément de
plancher), ou sur les systèmes devant satisfaire à des exigences de résistance au feu uniquement pour
l'allège, peuvent être effectués conformément à l'EN 1364-4. Pour les calfeutrements verticaux linéaires, la
présente partie de la norme s'applique.
La présente Norme européenne ne couvre pas les façades double peau, les systèmes de bardage et les
systèmes de façades ventilées sur des murs extérieurs. Elle ne traite pas du comportement au feu des murs
rideaux.
La présente norme est destinée à être lue conjointement avec l'EN 1363-1 et l'EN 1363-2.

6 Introduction CAUTION The attention of all persons concerned with managing and carrying out this fire resistance test is drawn to the fact that fire testing may be hazardous and that there is a possibility that toxic and/or harmful smoke and gases may be evolved during the test. Mechanical and operational hazards may also arise during the construction of the test elements or structures, during their testing and during the disposal of test residues. 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. SIST EN 1364-3:2014

1 Scope This European Standard specifies a method for determining the fire resistance of curtain walling – full configuration. This European Standard is used in conjunction with EN 1363-1. NOTE Annex B gives further information on the test method. The test method is applicable to curtain walling type B (for definition see 3.4). The test is not appropriate for testing curtain walling type A (for definition see 3.3). The fire resistance of curtain walling may be determined under internal or external exposure conditions. In the latter case the external fire exposure curve given in EN 1363-2 may be used, subject to deviating national regulations. Tests on individual parts of a curtain walling (e.g. perimeter seal, infill panel or fixing of the framing system (anchoring) used to attach the curtain walling to the floor element) or systems with fire resistance requirements only to the spandrel area may be performed using EN 1364-4. For vertical linear gap seals, this part of the standard applies. This European Standard 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 standard is intended to be read in conjunction with EN 1363-1 and EN 1363-2. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
