In tests with Compound T, using nitrogen driven gas shocked to reflected temperatures about 1150 K, the corresponding changes in time for induction delay and sample consumption for increases in reflected-shock pressure from 500 to 1500 psia were 400 to 50 and near zero to 500 microseconds, respectively. Although the induction time decreases at higher pressure the decreased consumption rate indicates a relatively slow-burning that is an improvement in explosion sensitivity. A vaporization mechanism which appears to be inhibited by high external pressure was proposed to be a rate-controlling step in the explosion transition of most CNF type compounds that were studied to date. In additional experiments, explosions were simulated by spark discharges so as to verify certain characteristics of the light and pressure sensors as used in shock-tube sensitivity testing of cryogenic compounds. Efforts to characterize the vaporization of inert freons were only partly successful.
