Anomalous Shock Sensitivity/Density Relationship for RDX-Polyethylene Wax and Related Formulations from MRL Small Scale Gap Test (SSGT) Measurements,

Shock sensitivity as measured by the MRL SSGT shows a consistent trend to lower values as TMD decreases for pressed RDX formulations and some pure explosives such as tetryl. Decrease in particle size, disruption of surface coating, critical diameter and run distance effects were all considered but found not to be the major cause. Comparison of MRL SSGT data for a series of production booster explosives with corresponding NOL SSGT data at 90 TMD suggested that the ability to undergo buildup is significantly more important for the MRL SSGT. Reasons for this difference are discussed, and limitations for assessment of data using the MRL SSGT are outlined.
