Forty-foot drop test

K) One-Hundred Foot Drop Test. The test is similar to "Forty-Foot Drop Test (described as Test No 103 in MIL-STD-331 and here as item f, under Physical Testing of Fuzes) and is used in some studies when it is considered that the 40-foot drop test is not severe enough (p IIB-33 of Ref 39)...

Forty Foot Drop Test. In this test, explosive components, such as bombs, are dropped 12.2 meters (40 feet) onto a hard impact surface. The impact surface consists of a steel plate on a concrete pad. The impact area is surrounded by walls of sufficient height and strength to contain the component during rebound. The component is dropped a number of times so different areas of the item are exposed to the impact. This test is used to determine the safety of both the component case and the contained explosive. No cracks, breaks, deformation, or displacement should occur in the component case. No explosion, burning, or charring of the explosive should occur.
