Hazard scenarios can involve multiple stimuli, such as heating followed by fragment impact. The shock response of LX-04 (85 weight % HMX and 15 weight % Viton binder) preheated to temperatures near 150°C is studied in a 10.2 cm bore diameter gas gun using embedded manganin pressure gauges. The pressure histories at various depths in the LX-04 targets and the run distances to detonation at several input shock pressures are measured and compared to those previously obtained in ambient temperature and 170°C LX-04. Since the beta to delta phase transition in HMX occurs at 165°C, these experiments are designed to determine whether the observed increase in shock sensitivity is due in part to the 6% volume expansion caused by this phase transition. The experiments show that LX-04 exhibits the same sensitivity at 150°C and 170°C. The Ignition and Growth reactive flow model developed for 170°C LX-04 works equally well for LX-04 at 150°C.
