Expressions QeV0 and 425Qe take no consideration of the velocity of detonation, a very important factor in the kind of expl action, and one which is very considerably affected by the physical condition of the expl, its aggregate state, density, crystal form and granulation, as well as by extreme conditions of detonation, such as the initiating impulse, confinement and tamping (Ref 2, p 153)... 

Properties of Composition C-4. It is a light -brown soft putty-like plastic explosive which can be hand-tamped to a density of 1.58 - 1.60 g/cc. Its brisance by sand test is 116% of TNT and by plate dent test, method B 115% (for unconfined hand-tamped material at d 1.60) detonation rate at RT, 8040m/sec, for unconfined, hand -tamped chge,diam 1, r d 1.59 Ditto - for sample kept at -54° for 16hrs 7020m/sec at d 1.36, vs 7040m/sec for sample at +21° explosion temperature - 290° in 5secs exudation - none at 77° friction pendulum test - unaffected by...
