European foreword
This document (prEN 13124-1:2022) has been prepared by Technical Committee CEN/TC 33 “Doors,
windows, shutters, building hardware and curtain walling”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13124-1:2001.
In comparison with the previous edition, the following technical modifications have been made:
— inclusion of façade testing;
— inclusion of hazard classes and the measurement connected to them;
— addition of term 3.5.3 “internal pressure”;
— clarification of the requirements for test setup and its connection to the test sample;
— editorial changes.
The EN 13124 series of standards Windows, doors, shutters and curtain walling — Explosion
resistance — Test method currently consists of:
— Part 1: Shock tube;
— Part 2: Range test.
1 Scope
This document specifies a conventional test procedure to permit classification of the explosion
resistance of windows, doors, shutters, together with their infills, as well as curtain walling elements.
This document concerns a method of test against blast waves generated using a shock tube facility to
simulate detonation events. This document considers high explosive detonations in the order of 100 kg
to 2 500 kg TNT equivalent at distances from about 35 m to 50 m, described by the fixed loading levels
EPR0 to EPR4. Scenarios characterized by variable blast parameters for further high explosive
detonations and gas or chemical explosions can also be specified.
This document covers only the behaviour of the complete test specimen including infill, frame and
fixings as tested.
This document gives no information on the ability of the surrounding wall or building structure to resist
the direct or transmitted forces.
If the windows, doors, shutters and curtain walling components are intended for specific conditions of
climate, specific test conditions can be required.
Requirements for the performance of opening and locking mechanisms or for testing in an open
condition can also be specified.
This document gives no information on the behaviour of the test specimens subjected to other types of
loading.

constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— IEC Electropedia: available at https://www.electropedia.org/
— ISO Online browsing platform: available at https://www.iso.org/obp
3.1
test specimen
window, door, shutter or curtain walling, which is prepared and submitted for testing
3.2
attack face
face of the test specimen, which is designed to face the explosion
3.3
rear face
opposite side of the test specimen to the attack face
3.4
explosion pressure resistance
EPR
resistance offered by the test specimen against a defined pressure wave, characterized by peak positive
reflected pressure, peak positive specific impulse and positive duration
3.5
pressure wave
explosion pressure pulse loading on the test specimen
Note 1 to entry: The pressure recorded and referred to is the reflected pressure experienced by the test specimen
when it is positioned at the end of the shock tube.
3.5.1
peak positive pressure
pmax
initial peak positive pressure above the ambient atmospheric pressure at the time of arrival of the pulse
at the test specimen
3.5.2
reflected pressure
pressure that occurs when a blast wave strikes the surface of a target, which obstructs the flow
Note 1 to entry: The shock wave moving through the air impacts the test specimen and is reflected producing a
pressure on the surface of the test specimen having a higher value than would have occurred within an
unobstructed flow.
3.5.3
internal pressure
pressure that is recorded in the test cubical
Note 1 to entry: For closed windows, this pressure is measured at the rear surface of the mounting frame. For
open windows, the pressure is measured one metre behind the inner face of the test sample. This will be
measured from the inner glass or the inner face of the door.
3.5.4
duration
duration of the first positive phase of the pressure trace (t )
+
3.5.5
pressure trace
t
+
graph of the pressure plotted against time
Note 1 to entry: See prEN 13123-1:2022, Figure 1.
3.5.6
peak positive specific impulse
i
+
parameter that is derived from the area under the pressure trace during the first positive phase
duration
Note 1 to entry: See hatched area in prEN 13123-1:2022, Figure 1.
3.5.7
minimum duration of the positive phase
t
Δ
duration of the equivalent pressure trace
Note 1 to entry: This is derived by a triangle having the same impulse area as the defined pressure trace and the
same peak positive reflected pressure.
Note 2 to entry: i.e. t = two times peak positive specific impulse divided by peak positive reflected pressure
Δ
expressed as
2⋅i

p

3.6
witness panel
panel of deformable material positioned behind the test specimen in order to register the incidence of
material forcibly detached from the test specimen during test
Note 1 to entry: The composition and location of the witness panel is described in 5.4 (d).
3.7
perforation
holes in the foil, cartridge paper or plain surface of the witness panel caused by impact of any material
as a result of the blast
3.8
united dimension of glass fragments
dimension of a glass fragment determined by adding its width and length and thickness.
Note 1 to entry: Glazing dust and slivers are all other smaller particles.
4 Requirements
Classification requirements for the explosion resistance of windows, doors, shutters and curtain walling
are given in prEN 13123-1:2022.
Additional requirements with respect to special conditions for surface temperatures or other boundary
conditions should be agreed between the test client and the test facility prior to a test as being suitable
for the purpose.
The test client should also specify any additional requirements for the locking and opening mechanisms
or whether the test specimen is to be tested in the open condition.
For the classification of the test specimen one successful test is required.
