Determination of Initiating Capability of Detonators by Underwater Explosion Test

New European standard of experimental procedure EN 13763-15 "Explosives for civil uses - Detonators and relays - Part 15: Determination of equivalent initiating capability" describes two methods enabling determination of initiating capability of detonators: underwater test for determination of detonators' energy and "witness plate" test for determination of influence of temperature on the effectiveness of detonators' function. This article describes the experimental arrangement and examples of test results of energy determined by underwater explosion test.
