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

EN 1364-4 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, or - the perimeter seal, or - the fixings of the framing system (anchoring) used to attach the curtain walling to the floor element, hereafter referred to as "fixing", or - combinations thereof Results from tests according to this standard form the basis for classification of curtain walling type A (see 3.2 for definition). For curtain walling type B (see 3.3 for definition) results may 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 shall be used. 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 as well as EN 1364-3 for curtain walling type B.

Feuerwiderstandsprüfungen für nichttragende Bauteile - Teil 4: Vorhangfassaden - Teilausführung

Diese Europäische Norm legt ein Verfahren zur Bestimmung der Feuerwiderstandsdauer von Teilen der Vorhangfassade und der Rand-Dichtung fest. Sie 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 Decken-element;
-   Kombinationen dieser Elemente.
Die Ergebnisse der Prüfungen nach dieser Norm bilden die Grundlage für die Klassifizierung von Vorhang-fassaden vom Typ A (siehe 3.3 für die Definition).
Für Vorhangfassaden vom Typ B (siehe 3.4 für die Definition) dürfen 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 Klassifi-zierung EW sowie bei Probekörpern mit Ecken/facettierten Probekörpern sollte EN 1364 3 angewendet werden.
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 sowie - für Vorhangfassaden vom Typ B - mit EN 1364 3 angewendet zu werden.
ANMERKUNG   Anhang A enthält informative Hinweise zu den Grundsätzen der Prüfung von Teilen von Vorhang-fassaden und zum Prüfverfahren.

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

La présente Norme européenne spécifie une méthode permettant de déterminer la résistance au feu de
parties de façade rideau et de l'étanchéité périphérique. Elle étudie la résistance au feu à l'exposition interne
et externe :
⎯ du panneau d'allège, c'est-à-dire panneau d’allège suspendu, en appui ou combinaison des deux ;
ou
⎯ de l'étanchéité périphérique ; ou
⎯ des fixations du système d'ossature (ancrage) utilisées pour attacher la façade rideau à l'élément de
plancher, ci-après désignées en tant que « fixation » ; ou
⎯ de combinaisons de ceux-ci.
Les résultats des essais réalisés conformément à la présente norme servent de base au classement d'une
façade rideau de type A (voir définition en 3.2).
Pour une façade rideau de type B (voir définition en 3.3), les résultats peuvent être utilisés pour déterminer la
résistance au feu de parties de la façade rideau afin d'étendre le domaine d'application, lorsqu'elle a été
préalablement soumise 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 doit être utilisée.
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
façades rideaux.
La présente norme est destinée à être lue conjointement à l'EN 1363-1 et à l'EN 1363-2 ainsi qu'à l'EN 1364-3
pour une façade rideau de type B.
NOTE L'Annexe A informative donne des lignes directrices concernant les principes et la méthode d'essai de parties
de façade rideau.

The minimum dimensions of the furnace are given in Figures B.1 to B.5. For the installation of the specimen, wall or floor furnaces shall be modified, if necessary, to accommodate the three-dimensional construction. The three dimensional construction includes the perimeter seal. The test according to EN 1364-4 is performed on a three-dimensional specimen to allow an exposure of a number of surfaces of the upstand/downstand (spandrel area) and incorporates a supporting floor, which provides the support for the curtain walling. 4.3 Supporting floor A supporting floor is provided as a base for the attachment of the fixing of the framing system and as a location for the perimeter seal under examination. If information on the fire resistance of the curtain walling in conjunction with a particular type of floor construction is required, such a construction shall be used, see 7.2. 5 Test conditions The pressure conditions and the furnace atmosphere shall conform to those given in EN 1363-1, subject to a nominal pressure of 20 Pa at the positions shown in Figures B.1 to B.5. The heating conditions shall conform to those given in EN 1363-1 and/or EN 1363-2 for the test configuration selected as given in Table 1. For details see Annex B. SIST EN 1364-4:2014



EN 1364-4:2014 (E) 10 6 Test specimen 6.1 Size The size of the test specimen shall be as follows: a) the height of the spandrel area as in practice (normally about 1 m), b) if the width of the curtain walling in practice is less than 3 m, the specimen shall be full size as in practice, c) if the width of the curtain walling in practice is larger than 3 m, the width of the specimen shall be not less than 3 m. NOTE 1 A width larger than 3 m may be the result of single panels with a width of more than 3 m or the result of the repetition of smaller construction units (mullion distance < 3m). NOTE 2 The height depends on national requirements. Where the width of a single spandrel panel (upstand/downstand) is less than 3 m, at least 3 panels with the mid panel at the maximum dimension shall be incorporated in the test specimen. Where the width of the panel is greater than or equal to 3 m, at least 3 panels with the mid panel at the maximum width shall be incorporated in the test specimen. The outer panels may be cut, subject to a minimum clearance between the mullions at the boundary of the mid panel and the inner surface of the furnace of 200 mm. The height h is the total of upstand and downstand (spandrel area). If the height of the specimen is smaller than the vertical opening of the furnace, the furnace opening shall be closed with a furnace closure according to 7.3. 6.2 Number of specimens The performance of curtain walling or parts of curtain walling type A for internal and external exposure shall be determined from a single test where the specimen is heated from both sides. For details see Annex B. For curtain walling type B separate tests shall be performed for internal and external exposure. NOTE Depending on national requirements the external exposure may be the external fire curve as specified in EN 1363–2 or the standard temperature/time curve as specified in EN 1363–1. 6.3 Design 6.3.1 General The test specimen shall be: — either fully representative of the construction intended for use in practice, including fixing of the framing system, expansion joints, perimeter seals, any surface finishes and fittings which are essential and may influence its behaviour in the test, or — a standard configuration as defined in Annex B. NOTE The use of a standard configuration allows the use of field of application rules to obtain the widest applicability of the test result to other similar constructions. The test specimen shall consist of parts of the curtain walling. It shall fully represent the construction on which information is required. For use of field of application rules, one of the standard configurations given in Table 1 as described in Annex B shall be used, see Clause 13. The test specimen shall consist of: SIST EN 1364-4:2014



EN 1364-4:2014 (E) 11 — the curtain walling part, — the perimeter seal and — the fixing of the framing system. If the scope of the test is the perimeter seal and movement capability is intended to be considered (see A.3.4) the fixing may be omitted. All design features which influence fire resistance performance shall be included. If the scope of the test includes an assessment of the fixing of the framing system additional load may be required to take account of the part of the curtain walling not included in the test. 6.3.2 Standard configuration 6.3.2.1 General A straight test specimen shall comprise a section of the curtain walling with minimum two mullions or two vertical joints between panels in case of systems without frame or mullions, fully exposed to the fire, see Figure 2. In case a T-connection and/ or cross connection is intended to be included these shall be located in the heated area. A transom shall be used on top and bottom of the spandrel panel except it is the intention of the test to demonstrate the performance of panels not fixed on top or bottom. A faceted specimen shall comprise minimum four sections of the curtain walling forming minimum one corner of 90 degrees and two angles of 135 degrees, all sections with a minimum width of 500 mm, minimum three sections with a width of minimum 1000 mm, see Figures 3A to 3D for examples. Two such specimens may be combined to a specimen forming two corners of 90 degrees and two angles of 135 degrees, see Figures 3E and 3F for examples. In case a transom is located in front of the floor slab in practice the test specimen shall also contain a transom in front of the supporting floor. Such a transom is not considered being part of the perimeter seal but part of the framing. A supporting floor shall be used for standard configurations 1, 2, 3 and 5. The design of the standard supporting floor is given in 7.2.1. 6.3.2.2 Test configuration for curtain walling type A The test specimen shall be heated from both sides at the same time. Depending on the requirements for the external exposure the heating of conditions of the standard temperature/time curve as specified in EN 1363-1 are maintained on one side only or on both sides of the specimen – for details see Figures B.1 and B.2. 6.3.2.3 Test configuration for curtain walling type B The test specimen shall be heated only from one side. In standard configurations for curtain walling type B the furnace closure or fire-resistant glazing may be positioned directl
