Introduction
General
When detonated, the explosive charge of detonators must provide enough initiating capability to initiate
the explosive or a detonating cord/shock tube, with which they are intended to be used.
In the test procedure described in this document, the output performance of a test piece is compared with
a reference of known characteristics and mass of charge. This document describes two tests: an
underwater initiating capability test and a functioning test at low and high temperatures.
Underwater initiating capability
This test is based on the principle that the detonation of an explosive charge under water generates a
spherical shock-wave and a volume of gas, which expands and then collapses as the bubble rises through
the water. The shock-wave and the volume of gas bear a finite relationship to the energy released. Thus,
by measuring:
— the shock-wave pressure; and
— the time interval between the shock-wave pressure peak and the first collapse of the gas bubble,
and calculating the parameters proportional to:
— equivalent shock energy; and
— equivalent bubble energy,
the energy output of the test detonators can be compared with the energy output of the reference
detonator to which the manufacturer claims equivalence.
Functioning test at high and low temperatures
This test checks that the energy output of the detonators does not vary when they are initiated at high
and low temperatures, by initiating detonators in contact with aluminium witness plates at ambient, high
and low temperatures and comparing the depths of indentations made in the plates.

The test piece is subject to an underwater initiating capability test where equivalent shock pressure peak
and rise time and equivalent bubble energy are calculated. The test piece is subject to a functioning test
at high and low temperatures. The depth of indentation in each of the witness plates are measured. In
