Shock velocity vs input pressure in the range of 32 to 112 GPa has been measured for LX-07, LX-17, PBX-9404, and RX-26-AF. The average shock velocity for the first 2.8-mm of run was found to be within one percent of that for the run from 2.0 to 4.8-mm. Supra-compressive states of PBX-9404 were reflected to higher pressures by a copper barrier and the velocity in the copper measured. They were also rarefied by a magnesium barrier and the velocity in the magnesium measured. Equations of state derived for the reaction products of these explosives and normalized to accepted C-J pressures do not adequately predict measurements at pressures substantially greater than detonation pressure, normalization to lower than accepted C-J pressures is required to fit the data. The C-J state defined by the supra-compressive experiments appears to be different from the C-J state defined by the usual C-J pressure measurement.
