4 General
The loading classes according to EN 13123-1:2025 are defined by pressure and impulse parameters and
represent free-field high explosive events caused by:
— 100 kg to 2 500 kg TNT equivalent at stand-off distances from about 35 m to 50 m, described in
EN 13123-1:2025 by the loading classes EPR0 to EPR4.
Other explosive scenarios can be characterized by user-defined loading class (EPRU) for high explosive
detonations and gas explosion scenarios.
Load profiles, which cannot be reproduced with the shock tube shall be reproduced by arena testing
according to EN 13123-2:2025 and EN 13124-2:2025.
If required, the assessment of the performance of opening and locking mechanisms or for testing in an
open condition can also be specified. The result gives no information on the behaviour of the test
specimens subjected to other types of loading.
5 Requirements
Classification requirements for the explosion resistance of windows, doors, shutters and curtain walling
are given in EN 13123-1:2025.
To achieve a particular class of explosion resistance,
a) the test specimen shall be subjected to a blast pressure wave generated in a shock tube. The peak
positive reflected pressure and the peak positive reflected specific impulse at the centre of the test
specimen shall both be within the tolerances in EN 13123-1:2025;
b) the internal damage will be assessed against the criteria shown in Table 1 and that letter code will
be appended to the explosion resistance class; and
c) if required by the sponsor of the test, the external damage may be assessed against the criteria shown
in Table 2 and that letter code will also be appended to the explosion resistance class.
Additional requirements with respect to special conditions for surface temperatures or other boundary
conditions shall be agreed between the sponsor of the test and the test laboratory prior to a test.
The sponsor of the test shall also specify any additional requirements for the locking and opening
mechanisms or whether the test specimen shall be tested in a partially open condition to replicate designs
incorporating natural ventilation for example.
For the classification of the test specimen one test fulfilling the requirements of this document is
sufficient.
6 Apparatus
6.1 Pressure generating device
It is a shock tube or similar device capable of reproducing the effects of a plane blast wave from a high
explosive, gas or chemical explosion.
6.2 Connections
Connections are the fixings, which integrate the test specimen into the test specimen support. They shall
allow the test specimen to be installed in a manner representative of its built condition without imposing
abnormal stresses. The sponsor of the test should provide installation instructions for the test including
the number, specification and location of fixings and these should be included in the test report.
The fixings should not be more ductile or weaker than in a real installation. Furthermore, the fixings
should not be stiffer or stronger than in real installation.
6.3 Test specimen support
The test specimen support shall be a frame or construction in which the test specimen (window, door or
curtain walling) and the fixings may be securely attached.
The following requirements shall be fulfilled:
a) The test specimen support shall be sufficiently strong to resist the explosive forces without imparting
deformations to the test specimen that do not represent real situations as defined by the sponsor of
the test. This shall be demonstrated by the test laboratory.
b) The test specimen support shall be closed on all sides and prevent passage of pressure other than
through deformation of the test specimen or if the test specimen design includes openings for
ventilation purposes.
c) The test specimen support shall allow pressure gauges be mounted next to the attack face and in the
same plane as the test specimen.
d) Any additional or purpose-made frames, supports, connections, fixing points methods, technical or
functional conditions and their designs shall be agreed between the sponsor of the test and the test
laboratory prior to a test as being suitable for the purpose and shall be part of the test report.
e) In order to limit clearing effects, the test laboratory shall verify that the loading at the corner of the
test specimen is within the tolerances specified in EN 13123-1:2025.
f) If the test specimen shall be tested in the open condition, the space between the specimen and the
witness panel shall be enclosed so that the internal pressure can be measured.
6.4 Connections
Connections are the fixings which integrate the test specimen into the reaction structure. They shall allow
the test specimen be installed in a manner representative of its built condition without imposing
abnormal stresses. The sponsor of the test should provide installation instructions for the test including
the number, specification and location of fixings and these should be included in the test report.
The fixings should neither be more ductile nor weaker than in a real installation. Furthermore, the fixings
should not be stiffer or stronger than in a real installation.
6.5 Equipment for measuring
Equipment shall comprise:
a) thermometers
Thermometers shall be suitable for measuring the ambient air temperature and the temperature of
the attack and the rear face of the test specimen, taking into account variations due to shade, sunlight
or other weather conditions to an accuracy of ±1 °C. Measurements shall be taken at the time of the
test. It shall be ensured that either the ambient temperature is 18 °C (±10 °C) or the back surface
temperature is 18 °C (±5 °C);
b) a barometer
The barometer shall be suitable for measuring the ambient air pressure outside the shock tube to an
accuracy of ±0,2 kPa.
c) pressure gauges
Pressure gauges are instrumentation systems for measuring and recording the pressure history of
the blast wave. These shall be gauges incorporating piezoelectric/piezoresistive or equivalent
pressure transducers with:
1) full scale range of 0 kPa to 500 kPa (absolute);
2) resonance frequency greater than 50 kHz;
3) transducer resolution less than 0,1 kPa;
4) nonlinearity less than 1 %;
5) current calibration certificates covering the pressure range being measured.
The gauges shall be mounted in suitably shaped, robust mountings designed to minimize vibration
effects.
At least three gauges shall be deployed at each location at the attack face of the test specimen so that
any gauges providing faulty readings can be identified and those gauges’ data can be discarded.
d) data recorders
Data recorders should have:
1) the capability to record at a minimum sample rate of 100 samples per millisecond (100 kHz);
2) a time base range of at least 1 000 milliseconds;
3) a pre-trigger range of at least 100 milliseconds;
4) a hardware (analogue) anti-aliasing, low pass band limited filter at greater than 10 kHz;
5) a bandwidth greate
