The authors have measured the volumetric behavior of paste extrudable explosive RX-08-FK using two methods: high-precision dilatometry at atmospheric pressure and temperatures from [minus]30 to +85C and compression testing in a specially designed piston-type rheometer in which the orifice was replaced with a blank. Compression measurements were made at six temperatures from [minus]54 to +74C and at many pressures up to 70 MPa. The volume coefficient of expansion of the paste at 1 atm is very nearly constant over the temperature range tested, averaging (3.643 [plus minus] 0.005) x 10[sup [minus]4]K[sup [minus]1]. In compression tests, at a given volume, the observed pressure was 3-15 MPa a higher when pressure was rising than when it was falling, possibly because of O-ring drag. The specific volume of the paste over the field of temperature and pressure was well described by a simple equation of state: v/(cm[sup 3]/g) = 0.50977 + 0.16683(T/K)/(P/MPa + 801.41), s[sub e](v/(cm[sup 3]/g)) = 0.00026.
