The Comparative Sensitivity of 'Superfine'PETN and Dextrinated Lead Azide.

摘要

The sensitivity of two different lots of a special grade of PETN, designated as 'superfine' PETN was compared with that of dextrinated lead azide with respect to impact, shock, short high temperature pulses, and gaseous electrostatic discharge. Results of the seven tests employed showed that both lots were clearly less sensitive than the reference dextrinated lead azide. Responses were not markedly different than those of standard PETN (Mil-P-387). The test for initiation sensitivity (minimum priming charge) did, however, indicate that the test explosive is more sensitive than most of the secondary explosives. (Author)
