SIST EN 13763-15:2005

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 fired at high and low temperatures, by firing detonators in contact with aluminium witness plates at ambient, high and low temperatures and comparing the depths of indentations made in the plates.
