Dieses Dokument legt die Anforderungen und Klassifizierung für die Bewertung der Explosionsfestigkeit von Fenstern, Türen, Abschlüssen sowie Vorhangfassadenelementen einschließlich deren Rahmen, Füllungen und Befestigungen für den Einsatz im Innen- und Außenbereich von Gebäuden fest, wenn sie einem Freilandversuch nach FprEN 13124 2:2025 unterzogen werden.

Fenêtres, portes, fermetures et façades rideaux - Résistance à l'explosion - Exigences et classification - Partie 2 : Essai en arène
Le présent document spécifie les critères auxquels doivent satisfaire les fenêtres, les portes, les fermetures ainsi que les éléments de façades rideaux pour pouvoir obtenir une classification, lorsqu'ils sont soumis à la méthode d'essai décrite dans la prEN 13124-2:2023.
Le présent document concerne une méthode d'essai de résistance aux ondes de choc produites par des explosifs puissants dans un essai en arène. Le présent document prend en compte des événements de forte explosion en champ libre, de l'ordre de :
- 3 kg à 20 kg (équivalent TNT) à des distances de 3 m à 9 m, décrites par les niveaux de classification fixes PXR 1 à PXR 7 ;
- 100 kg à 500 kg (équivalent TNT) à des distances d'environ 15 m à 30 m, décrites par les niveaux de classification fixes VXR 1 à VXR 7.
Cette méthode permet d'obtenir une classification selon la norme prEN 13124-2:2023. Les masses indicatives des charges explosives et les distances d'explosion correspondant à ces classifications sont indiquées à l'Annexe B.
Des ondes de choc caractérisées par les paramètres de souffle spécifiés par l'utilisateur pour d'autres scénarios de forte explosion peuvent également être spécifiées.
Les ondes de choc qui ne peuvent pas être produites lors d'un essai en arène peuvent être produites par un essai de tube à effet de souffle (shock tube) conformément aux normes prEN 13123-1:2022 et prEN 13124-1:2022.
Le présent document s'applique aux ondes de choc générées par des explosifs dans une installation d'essai en arène, pour produire des ondes de choc sur des fenêtres, des portes, des fermetures, ainsi que sur des systèmes de façades rideaux, y compris sur leurs dormants, leurs remplissages et leurs fixations, à l'intérieur et à l'extérieur des bâtiments. Il ne donne aucune information quant à la capacité de résistance à l'explosion du mur ou de la structure environnante.

4 General
This document considers free-field high explosive events equivalent to:
— 3 kg to 20 kg TNT equivalent at distances from 3 m to 9 m, described by the loading classes PXR 1 to
PXR 7;
— 100 kg to 500 kg TNT equivalent at distances from about 15 m to 30 m, described by the loading
classes VXR 1 to VXR 7.
Other explosive scenarios can be characterized by user-defined loading classes (PXRU or VXRU) for high
explosive detonations.
Load profiles, which cannot be reproduced by an arena test shall be reproduced by shock tube testing
according to EN 13123-1:2025 and EN 13124-1:2025.
5 Requirements
Resistance to damage and pressure shall be classified in accordance with Clause 6. This document
provides the option to do tests either:
a) for fixed loading classes (PXR and VXR classes); or
b) for user-defined loading class (PXU and VXU classes) with specified parameters for peak positive
reflected pressure and peak positive reflected specific impulse.
To achieve a particular loading class of explosion resistance, the test specimen shall:
a) be subjected to not less than the corresponding test level of each of peak positive reflected pressure,
peak positive reflected specific impulse specified in Clause 6, Table 1, Table 2 and Figure 1;
b) achieve an internal hazard class as specified in EN 13124-2:2025, 11.2;
c) if required by the test client, achieve an external hazard class as specified in EN 13124-2 :2025, 11.3.
It is not a requirement of the test that performance in other respects such as air permeability, water
tightness, wind resistance, etc. be maintained.
If the intended application of the window, door, shutter and curtain walling is such that it will be
specifically subjected to climatic extremes, the test specimen shall be tested at these climatic extremes if
required by the test client.
Requirements for the performance of opening and locking mechanisms or for testing in an open condition
may also be tested if required by the test client.
Care should be taken to ensure that all joints between the wall and the window or door have protection,
which is at least equal to that of the window or door, shutter and curtain walling.
6 Loading classes for blast pressure resistance (PXR and VXR)
The loading class of a test specimen is permitted for both:
a) predefined loading classes (PXR 1 to PXR 7 and VXR 1 to VXR 7) with respect to peak positive
reflected pressure and peak positive reflected specific impulse (Table 1 and Table 2). When a tested
test specimen achieves a particular loading class it also automatically achieves all classes
characterized by lower peak pressure and lower peak positive reflected specific impulse at the same
hazard level(s).
b) user-defined loading classes described by peak positive reflected pressure and peak positive
reflected specific impulse complementing the PXR and VXR classes to a wide range of possible
loading classes suitable for various blast scenarios due to high explosive detonations.

VXR U definition by the user definition by the user
Allowable tolerances:
Peak positive reflected pressure between 0 % and +20 %;
Peak positive reflected specific impulse between 0 % and +20 %
To ensure that clearing effects are managed, the impulse value at the top corners of the test sample should
be no more than 10 % below the expected impulse value at that point when the loading class value is
achieved at the centre of the test specimen.
The loading class refers to the peak positive reflected pressure and peak positive reflected specific
impulse values which the test specimen experiences. The loading class also includes the internal hazard
class and, if required by the test client, the external hazard class.
Peak positive reflected pressure, peak positive reflected specific impulse and positive duration values
shall be determined in accordance with Annex A. The decay coefficient defining the shape of the mean
pressure trace shall lie within the values 0 to 4.
A user-defined loading class shall contain the values of peak positive reflected pressure and peak positive
reflected specific impulse.
Results of the tests is further annotated with hazard class according to EN 13124-2:2025. Test results
achieved according to EN 13123-2:2004 with a rating EXR NS are equivalent to hazard class B, and with
a rating EXR S are equivalent to hazard class C.
The test criteria are the blast parameters shown in Table 1 and Table 2. For convenience, Table B.1 and
Table B.2 of Annex B show approximate charge masses and stand-off distances for the standard loading
classes.
Products tested according to EN 13123-2:2004 may be classified under this document, EN 13123-2:2025,
provided that both pressure and impulse values are achieved or exceeded.

EN 13123-2:2004 is giv
