There are standardized methods for determining TNT Equivalency. With modern measurement instrumentation, it is possible to be more precise in obtaining pressure and impulse values because of greater resolution and accuracy. Preliminary results of recent cast TNT hemispherical tests indicate that new peak pressure values versus scaled distances could shift the standard TNT reference curve to the right. Airblast parameters measured on 44 explosives, propellants, and pyrotechnics indicated higher peak pressure and impulse values, due primarily to geometries, reflecting surface, and state-of-the-art instrumentation systems.
