Sa. Formby et Rk. Wharton, BLAST CHARACTERISTICS AND TNT EQUIVALENCE VALUES FOR SOME COMMERCIAL EXPLOSIVES DETONATED AT GROUND-LEVEL, Journal of hazardous materials, 50(2-3), 1996, pp. 183-198
We report measurement of the pressure-time profiles produced by the in
itiation at ground level of four common commercial sector explosives w
ith different detonation velocities, The results indicate that there a
re no significant differences in the blast waveshapes from the explosi
ves when measured at distances of 25 and 50 m from the initiation poin
t. Analysis of both peak overpressure and positive phase impulse data
has yielded values for the TNT Equivalence of the materials at two sca
led distances. Our work indicates that the TNT Equivalence values of t
he materials studied vary with scaled distance and on whether they are
evaluated from overpressure or impulse.
