Basic experiments to measure blast pressures were carried out in a closed explosion chamber at NIMC. As a result, several technical findings on pressure-time profile measurements and evaluation method of a TNT-equivalent were found out. Moreover, standard equations for blast parameters were established from a series of pentolite detonations. Finally, the validity of the standard equations was examined by applying to evaluation of explosive strength of a slurry explosive.
