27、4 (E) 5 Introduction General When fired, the explosive charge of detonators must provide a pulse of sufficient energy 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
28、 piece is compared with a reference having 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 detonati
29、on 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
30、 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 de
31、tonator 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 fired at high and low temperatures, by firing detonators in contact with aluminium witness plates at ambient, high
32、 and low temperatures and comparing the depths of indentations made in the plates.
