This report addresses the implications of the presence of both conventional and insensitive munitions (IM) in a national stockpile, and presents theoretical methods to determine a critical amount or fraction of IM that may avoid escalation of accident scenarios (e.g.

When dealing with energetic materials, TNT equivalency is commonly used for different purposes. For scientific purposes, it is a means to compare the explosive effects delivered by different energetic compositions, by expressing them in terms of an equivalent TNT detonation.

MSIAC maintains a Hazard Classification (HC) database for Ammunition and Explosives (AE) with 16 contributing nations. Governmental personnel from MSIAC member nations are able to access the data through the MSIAC secure website.

A probabilistic analytic model of initiation for the STANAG 4496 Insensitive Munitions (IM) Fragment Impact (FI) test was developed. The deterministic Jacobs-Roslund (JR) detonation initiation model was augmented to include impact point offset and fragment tilt against a curved munition case.

An analysis has been conducted to develop a method to estimate critical loading density conditions that, after the deflagration ignition of the munitions in a magazine, will lead to transition to detonation of these munitions.
During the 2018 MSIAC Improved Explosives and Munitions Risk Management (IEMRM) workshop, it was recognized by the community that low violence reaction types such as a burn on one side, and high violence reactions such as detonations on the other side, are relatively well understood.
