4 Principle
The initiating capability of a detonator is an important characteristic with regard to safe and reliable
functioning.
For the verification of the initiating capability of a detonator, test pieces are subjected to an underwater
test and to a plate dent test.
By means of the underwater test it is verified that the detonator to be tested, shows an equal or stronger
initiating capability than the specified corresponding reference detonator. Test pieces and reference
detonators are initiated under water. From the measured pressure over time, the values of the so-called
equivalent shock energy and equivalent bubble energy are calculated and used as indicators for the
comparison of the initiating capability.
NOTE The detonation of an explosive charge under water generates a spherical shock wave and a volume of
gas in a bubble, which expands and then collapses. The shock wave and the volume of gas bear a specific relationship
indicating the energy released through the detonation. The parameters equivalent shock energy and equivalent
bubble energy represent this energy but aren’t energy values themselves; they can be derived from the measured
shock wave pressure and the time between the maximum pressure peak and the first collapse of the gas bubble.
By means of the plate dent test it is verified that the tested detonator shows an initiating capability over
the specified temperature range of use that does not deviate too much from the performance at
(20 ± 5) °C. Test pieces are either conditioned at (20 ± 5) °C, at the minimum temperature of use or at the
highest temperature of use as specified for the detonator, and then initiated after being placed on a
witness plate. The obtained indentations on the witness plates are measured and compared.
5 Apparatus
5.1 Water tank, with a volume of at least 500 l and with minimum dimensions to immerse the
positioning frame (5.2) with the attached test piece (see Clause 6) and the pressure sensor (5.3) so that
a distance between the test piece and any other object is ≥ 200 mm, see Figure 1.
As an alternative, a body of water for carrying out blasting tests may be used instead of a water tank.
5.2 Positioning frame, made from a material that is dimensionally stable when immersed into water
for duration of the test (see Clause 7). The positioning frame shall allow the immersion of a test piece (see
Clause 6) or a reference detonator (5.9), respectively, and the pressure sensor (5.3) to water depth of
(400 ± 5) mm as measured from the lowest points of the test piece or the reference detonator (5.9) as
shown in Figure 1. The positioning frame shall keep the test piece or the reference detonator and the
pressure sensor at a horizontal distance of (400 ± 5) mm measured between their centrelines (see
Figure 1).
