Recent Advances on Thermal Safety Characterization of Energetic Materials

Understanding the response of energetic material to thermal insults is very important for the storage, transportation, and handling of energetic materials. One dimensional time to explosion (ODTX) is one approach to characterize thermal behavior. Time to explosion and explosion violence have been measured on many materials and the data have been used for the construction of cook-off models. Recent upgrades to the ODTX system allow monitoring of gas pressure (P-ODTX) during thermal experiments, which is important for the model validation. This paper addresses recent ODTX data on time to explosion and thermal explosion violence; P-ODTX data on cook-off temperature and pressure behavior during thermal explosion; C-ODTX data on development of gas evolution monitoring during heating of explosives under confinement.
