A SMALL SCALE GAP SENSITIVITY TEST

Abstract

This report describes a method whereby the sensitivity of explosives to initiation by other explosives may be evaluated when only a small sample of the explosive is available. Cylindrical brass containers 1" in diameter and l/4" long8 with 0.100" diamieter centrally drilled holes were used to contain the explosive to be tested. The use of such small columns makes it possible to obtain statistically valuable data from small amounts of explosive. The depth of a dent in a steel block placed at the back of the explosive column was used as a criterion to determine whether the shot was a fire or misfire. The order of decreasing sensitivity of the five explosives tested was found to be RDX, tetryl, Comp B, TNT and Comp A. This is in agreement with results of stmilar larger scale experiments.
