4 Principle
Safe and reliable transmission of detonation of cartridged explosives for blasting from one end of the
train of cartridges to the other is an important characteristic with regard to correct functioning.
The transmission of detonation is verified by testing the ability of two cartridges to transmit the
detonation from one to the other. The cartridges are not in direct contact with each other. Transmission
of detonation is given when complete detonation of the acceptor charge is observed. The acceptor charge
is the cartridge that receives the pressure wave from the detonation of the other cartridge (donor charge)
after its initiation. Complete detonation is determined by measuring the velocity of detonation and
comparing it to the value specified for the cartridged explosive tested. Testing is done at the minimum
temperature of use as specified for the explosive.
5 Apparatus
5.1 Means of initiation, as specified for the explosive tested in accordance with
EN 13631-1:2025, 4.1.4, being a detonator, a detonating cord with a detonator or a booster with a
detonator.
5.2 Steel tube, of steel grade S 235 in accordance with EN 10025-2:2019, Clause 4 and Tables 1, 3 and
6, and with dimensions in accordance with EN 10216-1:2013, Table 7.
In case of cartridged explosives being tested under confinement, the resulting inner diameter of the steel
tube shall have the smallest diameter where the cartridges with the minimum diameter specified in
accordance with EN 13631-1:2025, 4.1.9, together with the means of initiations (5.1), the support (5.3)
and the means to measure the velocity of detonation (5.4) can still be inserted.
The wall thickness of the steel tube shall be the smallest preferred value as given for the outer diameter
in EN 10216-1:2013, Table 7.
If the start-stop-method (5.4.1) is used for measuring the velocity of detonation, there shall be two holes
in the tube to allow the insertion of the sensors of the measuring equipment at positions in accordance
with 7.1.2. The diameter of the holes shall be just large enough for the sensors to be inserted.
5.3 Support, to axially align the cartridges, ensure the distance (see key D of Figure 1) between these
and, in case of a test without confinement, to suspend the test assembly as specified in 7.1. The support
shall not have an influence on the test result.
NOTE A thin rod made from metal or wood, a wire or a thin rope.
5.4 Velocity of detonation measuring equipment, capable of measuring the velocity of up to
10 000 m/s with a tolerance of ± 100 m/s, being one of the following:
5.4.1 Measuring equipment for the start-stop-method, consisting of two sensors capable of
detecting the passing of the detonation front and the electronic equipment to record the time between
the signals as received from the two sensors.
NOTE Examples of sensors are optical fibres, self-shorting pins, ionization pins and piezoelectric pins.
5.4.2 Measuring equipment for the continuous method, consisting of a continuous probe and
electronic equipment to record the signal from the continuous probe and to derive the velocity of
detonation.
NOTE The continuous probe can be made from, for example, a thin rigid copper rod or a coaxial cable.
5.5 Length gauge, capable of measuring a length up to 200 cm readable to the nearest 1 mm.
5.6 Calliper, capable of measuring a length up to 200 mm readable to the nearest 0,1 mm.
5.7 Balance, capable of measuring a weight up to 10 kg readable to the nearest 1 g.
5.8 Adhesive tape, made from paper, plastic or textile, capable of attaching cartridged explosives to
each other using one layer of tape.
5.9 Conditioning chamber, a
