Peak side-on overpressure and side-on impulse as a function of distance have been determined for 17 propellant formulations in a series of 31 shots. TNT equivalents based on overpressure and TNT equivalents based on impulse have been assigned the formulations examined. Blast overpressures and impulses were generated by 100-lbm propellant charges initiated with 25 lbm of high explosive and measured at distances from 40 to 80 feet from ground zero. It has been found that, depending on formulation, non-detonable propellants exhibit a TNT equivalent of 55 to 85 and that detonable propellants exhibit a TNT equivalent of 100 to 140. These TNT equivalents should be used in hazards classification only when stimuli are comparable.
