Four sets of rules for predicting the detonation product compositions of explosives have been investigated: the Kamlet-Jacobs, the KistiakowskyWilson, the modified Kistiakowsky-Wilson and the Springall-Roberts. These can result, for a given compound, in significantly differing detonation products and amounts of heat release. However the resulting detonation velocities D and detonation pressures P obtained for the compound using the Kamlet-Jacobs equations are generally quite similar, with the Kamlet-Jacobs rules leading to the D and P that are, on average, closest to the experimental. The fact that the variations among the D and P values are relatively small can be attributed to a balancing of opposing effects relating to the quantities of gaseous products and the heat releases. Accordingly, obtaining reasonable accuracy for D and P does not necessarily imply corresponding accuracy for the product composition and heat release that were used. The analysis presented explains the observations that D and P can be correlated with loading density alone, even though product compositions are known to change with density.
