Fire resistance tests for non-loadbearing elements - Part 3: Curtain walling - Full configuration (complete assembly)
EN 1364-3 specifies a method for determining the fire resistance of curtain walling - full configuration. EN ISO 13857This European Standard is used in conjunction with EN 1363-1. 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
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.

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 3.3). The test is not appropriate for
testing curtain walling type A (for definition see 3.2).
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 fixings of the framing system
(anchoring) used to attach the curtain walling to the floor element, hereafter referred to as "fixing") or systems
with fire resistance requirements only to the spandrel area may be performed using EN 1364-4. For vertical
linear gap seals, this standard (EN 1364-3) 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

4.1 General
In addition to the test equipment specified in EN 1363-1, and if applicable EN 1363-2, the equipment as
specified in 4.2 and 4.3 is required for internal or external exposure.
4.2 Internal exposure
The test equipment includes:
two floors adequately supported by the floor of the laboratory and/or the furnace;
associated and/or simulated wall constructions which provide an enclosure between the furnace and the
specimen.
4.3 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.
5 Test conditions
The heating and pressure conditions and the furnace atmosphere shall conform to those given in EN 1363-1
or, if applicable, EN 1363-2 which are related to the external fire curve.
6 Test specimen
6.1 Size
6.1.1 General
The exposed width and height shall not be less than 3 m.
There shall be a clearance of minimum 50 mm between the floor of the test room (or any other element under
the edge of the test specimen to give support) and the bottom edge of the test specimen (see Figures 3 and
4).
6.1.1.1 Internal fire exposure
The test specimen (see Figure 3) shall be of sufficient height to allow:
7
---------------------- Page: 9 ----------------------
oSIST prEN 1364-3:2012
prEN 1364-3:2011 (E)
a) the inclusion of a spandrel area in front of the upper supporting floor as in practice. The spandrel may be
cut in height so that it extends minimum 500 mm beyond the top of the upper supporting floor, if
applicable.
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.
6.1.2 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 4).
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 shall be:
a) either fully representative of the construction intended for use in practice, including fixings, expansion
joints, linear gap seals, any surface finishes and fittings which are essential and may influence its
behaviour in the test, or
b) be a standard construction as defined in 6.3.2.
6.3.2 Standard configuration
6.3.2.1 General
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 5. One of the mullions and transoms may be interrupted to allow the inclusion
of T-connections. Figure 6 shows an example for the standard configuration of a test specimen including a
vertical linear gap seal. Figure 7 shows an example for the standard configuration of a specimen including
horizontal and vertical T-connections.
A faceted specimen shall comprise minimum four sections of the curtain walling forming minimum one corner
of 90 degrees and two facet 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 for examples. Two such specimens
may be combined to a specimen forming two corners of 90 degrees and two facet angles of 135 degrees, see
Figures 8E and 8F 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.

6.3.2.2 Internal exposure
The test specimen for internal exposure shall include the curtain walling, the perimeter seals, if required, the
vertical linear gap seal with the simulated wall and two supporting floors.
If the vertical linear gap seal is not part of the test specimen, then two associated wall constructions are
required.
6.3.2.3 External exposure
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. For standard configurations see Figure 9.
The vertical edges of the test specimen shall be unrestrained.
In case a test specimen according to Figures 9B and 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
6.3.3 Restraint
The test specimen for internal exposure shall be fixed to the top and bottom supporting floor with the type of
fixings used in practice. The test specimen for external exposure shall be either fixed to a frame or fixed to the
top or the bottom of the furnace as illustrated in Figure 9.
Both vertical edges shall be unrestrained. A suitable furnace closure at the free edge between the associated
and/or simulated wall construction and the mullions shall be used that allows unrestrained movement of the
mullions (see Figure 10 for options).
Maximum movement of the mullion is achieved when option A for detail D1 in Figure 10 is used.
6.3.4 Surfaces
For definition of the surfaces for the installation of the thermocouples see Figure 3 for internal exposure and
Figure 4 for external exposure.
NOTE Surface S2 is the external surface of the curtain walling.
6.3.5 Perimeter seal
In case mineral wool is used as backfilling material variations of the mineral wool may be used within one test
specimen provided the length of the seal with a particular backfilling material is minimum the same as the
distance between two mullions and it is located such that the splice between different backfilling materials is
not located in the area of the mullion.
6.4 Construction
The test specimen shall be constructed as described in EN 1363-1, subject to deviating rules given in this
standard.

prEN 1364-3:2011 (E)
In case a component of the curtain walling is cut all open gaps at the top end of the curtain walling shall be
closed using material of class A1 according to EN 13501-1.
6.5 Verification
Verification of the test specimen shall be carried out as described in EN 1363-1.
7 Installation of the test specimen
7.1 General
The test specimen shall be fitted to the supporting floors by means of the fixings that are used in practice, see
7.2.
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 18). The floor
shall be made of reinforced concrete or made of reinforced aerated concrete and shall be restrained at both
ends.
NOTE A wider supporting floor may be necessary to avoid failure of the floor for test durations of 90 minutes or more.
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.
8 Conditioning
The test construction shall be conditioned in accordance with EN 1363-1.

9 Application of instrumentation
9.1 Thermocouples
9.1.1 Furnace thermocouples (plate thermometers)
Plate thermometers shall be provided in accordance with EN 1363-1. There shall be at least one for every
2
1,5 m of the exposed surface area of the test construction, subject to a minimum of four. The plate
thermometers shall be oriented so that side ‘A’ faces the back wall of the furnace. For details of location of
plate thermometers in case of faceted specimens see Figures 11 and 12.
9.1.2 Unexposed face thermocouples
9.1.2.1 General
The general rules for the attachment and exclusion of unexposed face thermocouples given in EN 1363-1
shall apply.
For internal exposure, if it is not necessary to evaluate the insulation criteria for Surfaces 2 and 6 then the
thermocouples may be omitted.
9.1.2.2 Mean temperature rise
2
The mean temperature rise shall be measured on each discrete infill / panel area ≥ 0,1 m by means of one
2
thermocouple per 1,5 m , subject to minimum two thermocouples per discrete area. The mean temperature
rise shall only be measured in the upper spandrel area and the non-spandrel area (e.g. vision glass area). The
thermocouples shall be located in two opposite corners at a distance of approximately a third of the width and
approximately a third of the length of the discrete area. For illustration see Figure 13. If due to the size of the
discrete area a third thermocouple is required it shall be positioned close to the centre of the discrete area. In
case more thermocouples are required, one shall be located close to the centre of the infill / panel and the
others close to the centre of each quarter section. Records from all discrete areas of the same type shall be
used for calculating the mean temperature rise. Thermocouples shall not be positioned closer than 100 mm
from any discrete area that is not being evaluated for insulation.
For test specimens which are non-uniform, i.e. those which have surface corrugations or ribs, the temperature
of each area/surface type shall be monitored to determine the mean temperature rise.
As there are no evaluation criteria for the perimeter seal, the mean temperature rise is not measured.
9.1.2.3 Maximum temperature rise
9.1.2.3.1 General
Thermocouples for the determination of maximum temperature rise may need to be added or their location be
changed for particular constructions other than the ones shown in Figures 5 to 7 (straight specimen) and 17 to
19 (faceted specimen). Clauses 9.1.2.3.2 to 9.1.2.3.6 for the location of thermocouples for determination of
maximum temperature rise are obligatory for standard configurations and are given as guidance for non-
standard configurations.
The mean temperature rise thermocouples shall also be used to evaluate the maximum temperature rise.
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 14 for straight specimens and Figure 17 for faceted specimens:

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;
