Shock sensitivity testing of Octols

Octol 60/40 and 70/30 (HMX/TNT) have been tested with regard to shock sensitivity in Intermediate Scale GAP test. Both compositions were cast filled into the test tubes. An average density of 98.1% of TMD was obtained for the fillings with Octol 60/40 and 98.2 % of TMD for the fillings with Octol 70/30. The shock sensitivity for Octol 60/40 was found to be 14.5 kbar and for Octol 70/30 16.0 kbar, indicating that Octol 60/40 is slightly more shock sensitive than Octol 70/30.
