TEXT: The aim of this experiment was to measure the following pa-
rameters of a blast waves frontal pressure AIR impulse Ip time of
duration T+ and length A of compression phasep at the distance
higher than 5r 0 (r0 initial radius of the charge). The measure-
mentB were -taken of p f(t) at the given distance, using piezo-
electric pressure gauges and oscillographic recording. The
