Initiation Tests

In detail, a test method is described which gives the delay times and build up distances of the initiation of squeeze cast or plastic bonded high explosive charges. A special test setup arrangement is used to observe the incoming detonation wave of a high explosive train as the donor or initiating charge and then the breakthrough of the detonation wave at the acceptor charge in the axial direction and in the 90 direction. This allows to define the shift of the detonation breakthrough in the longitudinal direction, and the corner turning distance in the transverse direction and the build up distances in both observed directions.
