Abstract: A transducer is fixedly positioned within a supporting frame, covered by a shield in underlying relation to an enclosure within which explosion pulses are generated for testing purposes. The explosion pulses are profiled during emergence thereof through an aperture in the shield onto a specimen of cellular protective material to be tested by positioning thereof on the transducer. The enclosure is filled with a fluid media such as water to establish a water column corresponding for example to an underwater environment within which such explosion pulses would be generated. The energy of the profiled explosion pulses, not absorbed within the specimen, is measured through the transducer and recorded as a function of time for evaluation of the explosion protective capability of the specimen material being tested.
