4 Principle
During transport and use, detonators can be exposed to electrostatic discharge (ESD) from human bodies,
machines, by lightning and by charge generated by detonation of explosives. Electric and electronic
detonators with leading wires can be initiated by ESD. Electronic detonators also can be functionally
damaged or, once commanded to fire, can misfire, or detonate at a time different from the programmed
delay time.
For the verification of the resistance to ESD, test pieces are subjected to electrostatic discharge in order
to check whether they detonate. The electrostatic discharge is applied to the test pieces either between
the two leading wires (pin-to-pin configuration, see Figure 1) or between the short-circuited leading
wires and the shell (pins-to-case configuration, see Figure 2). For electronic detonators it is also checked
whether the test pieces can be initiated and detonates at the programmed delay time.
5 Apparatus
5.1 Electrostatic discharge generator A (ESD generator A), for testing electric detonators, with a
selectable capacitance between 500 pF and 3 500 pF, a serial resistance selectable from 0,5 Ω to 5 kΩ and
an adjustable voltage up to 25 kV. The ESD generator shall be capable of applying five consecutive
discharges with a repetition rate of one per 10 s.
5.2 Electrostatic discharge generator B (ESD generator B), for testing electronic detonators, with a
selectable capacitance of (330 ± 16,5) pF and (2 000 ± 100) pF, a selectable serial resistance of ≤ 0,5 Ω
and (330 ± 16,5) Ω as well as an adjustable voltage between 800 V and 28 kV. The ESD generator shall be
−1
capable of applying five consecutive discharges with a repetition rate of 1 s .

6 Preparation of test sample
6.1 Electric detonators
50 test pieces shall be selected.
The electric detonators needed for the adjustment of the ESD generator in accordance with Annex A are
not included in the above 50 test pieces.
Replacement test pieces, which can be needed when carrying out the tests in 7.1.2 and 7.1.3, are not
included in the above 50 test pieces.
The length of leading wires of each test piece shall be the shortest length of leading wires specified in
accordance with EN 13763-1:2025, 4.2.1.5. For longer leading wires, the leading wires shall be cut down
to the length specified in accordance with EN 13763-1:2025, 4.2.1.5, with a tolerance of ± 0,05 m
measured from the upper edge of the detonator top. If the shortest available length is > 3,5 m, the leading
wires of each test piece shall be cut to a length of (3,5 ± 0,05) m.

1) The choice of sample size is based on the classification of defects that shall be avoided, critical, major and minor. The
classification of defects and size of test sample can be found in EN 13763-1:2025, Annex B.
If the detonator to be tested has a delay element and forms part of a delay series, select two samples
consisting of 25 test pieces each with delay times evenly distributed, including the detonators having the
shortest and the longest delay time of the delay series.
The insulation shall be removed from the ends of the leading wires of each test piece in order to have a
length between 10 mm and 20 mm of non-insulated electrical wire.
6.2 Electronic detonators
For electronic detonators without delay time, 200 test pieces shall be selected. For electronic detonators
with delay time, 350 test pieces shall be selected.
For electronic detonators with leading wires consisting of more than two conductors, the number of test
pieces shall be increased by the number calculated in accordance with Formulae (1) and (2).

The length of leading wires of each test piece shall be the shortest length of leading wires specified in
accordance with EN 13763-1:2025, 4.4.1.5. For longer leading wires, the leading wires shall be cut down
to the length specified in accordance with EN 13763-1:2025, 4.4.1.5, with a tolerance of ± 0,05 m
measured from the upper edge of the detonator top.
If the shortest available length is > 3,5 m, the leading wires of each test piece shall be cut to a length of
(3,5 ± 0,05) m. If the shortest available length is > 3,5 m and the detonator to be tested is equipped with
a connector, test pieces shall be selected from those detonators having the shortest length of leading
wires specified in accordance with EN 13763-1:2025, 4.4.1.5, without cutting down the length.
In case that the detonator to be tested is equipped with a connector, a piece of bus wire with a length of
(10 ± 1) cm shall be attached to the connector. The insulation of the bus wire shall be removed from the
free ends in order to have a length between 10 mm and 20 mm of non-insulated electrical wire. In case
that the bus wire is a twin wire, the wires shall be separated.
In case that the detonator to be tested is not equipped with a connector, the insulation shall be removed
from the ends of the leading wires of each test piece in order to have a length between 10 mm and 20 mm
of non-insulated electrical wire. In case that the leading wires of the test pieces are twin wires, the wires
shall be separated over a length of (10 ± 1) cm before removing the insulation.
NOTE The connector is a coupling device to connect the leading wires to the bus wire of the firing unit.
In case of pre-programmed electronic detonators, the test pieces used for the test in 7.2.2 shall be the
ones with longest delay time specified in accordance with EN 13763-1:2025, 4.4.1.8.3.
