Abstract : Laboratory experiments were conducted to obtain incident overpressure data from frangible spheres pressurized with a flash evaporating fluid in liquid and vapor form. Glass spheres under higher than ambient internal pressure of Freon-12 were purposely burst to obtain time histories of overpressure. Non-dimensional peak pressures, arrival and duration times, and impulses are presented, and whenever possible plotted and compared with compiled data for Pentolite high explosive. The data are generally quite repeatable and show differences from blast data produced by condensed high explosives.
