This report describes a series of tests that used an explosively-driven small-diameter shock tube to shatter simply-supported plates with relatively high-pressure, long-duration blast loads. To determine how the fragment size distribution changed with time due to, e.g., collisions between the fragments and the collector, the fragment size distribution was measured at three different times using three different techniques. Despite the wide of range test conditions, all of the tests in this series, surprisingly, produced a single universal mass distribution, after normalizing by the average fragment mass, to within the limited resolution of the measurement and analysis techniques used.
