ABSTRAKT

Ammunition must be hazard classified prior to transportation and storage. Hazards classification requires an external fire test, which is a difficult and costly procedure when applied to large diameter rocket motors. The development of a subscale alternate to the required full-scale external fire test is highly desirable. Current studies are ongoing to determine the development of a subscale alternate external fire test. Transportation accident data have been collected to determine the adequate thermal stimulus levels. A flow charting technique has been applied to evaluate the required conditions for a violent response and characterization testing has been initiated for two baseline propellants. Thermal diffusivity, decomposition, and small-scale cookoff tests have been performed.
