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.

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

10 b) the test specimen to extend 150 mm below the upper surface of the lower supporting floor with the bottom edge unsupported. If an assessment of a vertical linear gap is required, the test specimen shall then be of sufficient width to allow a minimum of 500 mm of the test specimen to extend beyond the outside of the simulated wall. 6.1.3 External fire exposure The test specimen shall be of sufficient height to allow the test specimen to extend minimum 150 mm below the upper surface of the lower supporting floor with the bottom edge unsupported in case the specimen is installed in front of the furnace (see Figure 3). 6.2 Number of specimens Separate tests are necessary for internal and external exposure conditions. Depending on the construction of the curtain walling and the intended field of application additional tests with faceted specimens may be necessary. 6.3 Design 6.3.1 General The test specimen for internal exposure shall include the curtain walling, the perimeter seal and, if required, the vertical linear gap seal. The test specimen for external exposure only includes the curtain walling. The supporting floors, the perimeter seal and the vertical linear gap seal may be omitted. The test specimen or test construction, if appropriate, shall be: a) either fully representative of the construction intended for use in practice, including fixing of the framing system, expansion joints, perimeter seals, vertical linear gap seals, any surface finishes and fittings which are essential and may influence its behaviour in the test, or b) a standard configuration as defined in 6.3.2. 6.3.2 Standard configuration A straight test specimen shall comprise a section of the curtain walling comprising minimum two mullions and two transoms or two vertical joints between panels in case of systems without a frame or mullions, fully exposed to the fire, see Figure 4. One of the mullions and transoms may be interrupted to allow the inclusion of T-connections. Figure 5 shows an example for the standard configuration of a test specimen including a vertical linear gap seal. Figure 6 shows an example for the standard configuration of a specimen including horizontal and vertical T-connections. Figure 7 shows details of the connection geometry between mullions and associated wall and simulated wall / vertical linear gap seal. 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 8A to 8D. Two such specimens may be combined to a specimen forming two corners of 90 degrees and two angles of 135 degrees, see Figures 8E and 8F for examples. The sequence of the segments of the combined specimens may be different to that shown in Figure 8E and 8F except that the 500 mm wide section shall always be on one end. SIST EN 1364-3:2014
12 7 Installation of the test specimen 7.1 General For internal exposure the test construction shall include the test specimen and in addition two supporting floors and two associated walls. In case a vertical linear gap seal is included in the test specimen a simulated wall is used instead of one associated wall. The test specimen shall be fitted to the supporting floors by means of the fixing of the framing system that is used in practice, see 7.2. For external exposure a supporting frame which supports the specimen and is designed to allow the specimen to be supported and located adjacent to the furnace in case an installation in front of the furnace is used. For standard configurations see Figure 9. In case a test specimen according to Figures 9B or 9C is intended to be used it shall comply with the following: a) the test specimen shall be rigidly fixed only on top (hanging curtain walling) or at bottom (standing curtain walling); b) the fixing on the opposite side as well as the adjacent furnace closure shall allow thermal extension of the specimen as in practice; NOTE A gap of 50 to 100 mm is considered sufficient to allow thermal extension as in practice. 7.2 Supporting floors 7.2.1 Standard supporting floor The standard supporting floor shall have a minimum thickness of 150 mm and minimum width of 500 mm for straight specimens. For faceted specimens the minimum width shall be 200 mm (see Figure 13). The floor shall be made of reinforced concrete or made of reinforced aerated concrete and shall be restrained at three sides. 7.2.2 Non-standard supporting floor Any floor construction as in practise may be used. The results of the test are limited to that floor construction only (no field of direct application concerning floor constructions). 7.3 Simulated wall construction 7.3.1 Standard construction The construction details of standard wall constructions shall be in accordance with EN 1363-1. The method of sealing the vertical linear gap between the test specimen and the simulated wall construction shall be recorded in the test report. 7.3.2 Non-standard construction Any wall construction as in practise may be used. The result of the test is limited to that construction only (no field of direct application). 7.4 Furnace closure The furnace closure shall be done with a mineral wool packing of class A1 according to EN 13501-1 to allow the specimen to move to a similar extent as in practice. SIST EN 1364-3:2014
14 9.1.2.3.2 Surface 1 For the determination of maximum temperature rise, additional thermocouples shall be applied to Surface 1 as follows and given in Figure 15 for straight specimens and Figure 12 for faceted specimens: — Thermocouple 1A - 20 mm below the upper edge of the visible spandrel panel area at mid width of the panel; — Thermocouple 1B - on a mullion 20 mm below the upper edge of the visible spandrel panel area; — Thermocouple 1C - at the junction of a mullion and a transom; — Thermocouple 1D – at mid height of the edge panel with the maximum height and/or largest area, 150 mm in from the outer panel edge in case of installation according to Figure 9B and 9C or minimum 150 mm in from the inner surface of the furnace wall in case of installation according to Figure 9A; — Thermocouple 1F - at mid way between two mullions, where possible, at a transom or a horizontal joint between infill panel / infill panel or infill panel / spandrel panel (in the positive pressure zone); — Thermocouple 1G - at mid way between two transoms, where possible, on a mullion or a vertical joint between infill panel / infill panel (in the positive pressure zone) for each type of infill panel; — Thermocouple 1H - at mid-height of the panel with the largest area, 20 mm from the mullion for each type of infill panel and spandrel panel. If the largest panel is not the tallest panel, then another thermocouple shall be placed at mid-height of the tallest panel, 20 mm from the mullion or the joint between panel / panel; — Thermocouple 1I – at mid-width of the panel with the largest area, 20 mm from the transom at the top edge of the panel for each type of infill panel and spandrel panel. If the largest panel is not the widest panel, then another thermocouple shall be placed at mid-width of the widest panel, 20 mm from the transom or the joint between panel / panel at the top edge of the panel. Thermocouples 1I are used when the upper transom of the panel is located in the heated area. If this is not the case, thermocouples 2K are used; — Thermocouple 1J – in the top corners of the panel with the largest area and additionally in the top corners of the highest placed panel, if this is not the same panel, for each type of infill panel and spandrel panel, 20 mm from the mullion and the transom. Thermocouples 1J are used when the upper transom of the panel is located in the heated area. If this is not the case, thermocouples 2K are used; — Thermocouple 1K – in the bottom corners of the highest placed non-glazed panel, if there is no upper transom in the heated area, for each type of panel, 20 mm from the mullion and the transom. 9.1.2.3.3 Surfaces 2 and 6 For the determination of maximum temperature rise, additional thermocouples shall be applied as follows and as given in Figures 4 to 6 for straight specimens and Figure 13 for faceted specimens: — Thermocouple 2A - 20 mm below the soffit of the upper supporting floor at mid width of a spandrel panel (Surface 2); — Thermocouple 2B - 20 mm below the soffit of the upper supporting floor in line with a mullion (Surface 2); — Thermocouple 2C - at the junction of a mullion and a transom (Surface 2); — Thermocouple 2F - at mid way between two mullions, where possible, at a transom or a horizontal joint between infill panel / infill panel or infill panel / spandrel panel (in the positive pressure zone) (Surface 2); SIST EN 1364-3:2014
16 — Thermocouples on Surface 4 are only required if a vertical linear gap seal is part of the test specimen. 9.1.2.3.5 Perimeter Seal For the determination of the maximum temperature rise, thermocouples shall be applied to the perimeter seal as follows (see Figures 4 to 6): — Thermocouple HV - at the top surface of the seal, centrally between the mullions and centrally across the perimeter seal; — Thermocouple HW - at the top surface of the seal 20 mm from a mullion centrally across the perimeter seal; — Thermocouple HV1 - at the top surface of the seal
