Various techniques for possible use in evaluating dynamic detonator output were investigated. High-speed cameras were used in detonator test firings to record the motion of detonator fragments, explosion gases, shocks in air and in water, and build-up to detonation in boosters. The M84 detonator fired in air has an initial case expansion velocity of 1560 meterssecond and an initial explosion gas expansion velocity of 2620 meterssecond. The peak shock pressure transmitted into water by the M84 is 46.2 kilobars. Each evaluation technique offers distinct advantages. However, measurements of underwater shock pressures and booster response appear likely to provide the best level of cost effectiveness.
