Abstract

Experimental results of accelerating rate calorimeter (ARC) and calculation results by the ASTM Chemical Thermodynamic and Energy Release Evaluation Program (CHETAH) were compared with literature data obtained from explosion propagation tests (BAM 50/60 steel tube tests or UN gap tests) in order to safely predict the explosibility of self-reactive materials. There is a mutual correlation between CHETAH criteria and the explosibility of self-reactive substances except in the cases of organic peroxides and azo compounds. There is also mutual correlation between maximum pressure per unit mol of substances measured by ARC and the explosibility of substances. Additionally, the temperature at maximum pressure rising rate is correlated with the explosibility of substances except in the case of nitro compounds.Consequently, the explosibility of self-reactive materials can be predicted by temperature and pressure measurements using ARC.
