A method of estimating the safe storage life (τ), self-accelerating decomposition temperature (TSADT) and critical temperature of thermal explosion (Tb) of double-base propellant using isothermal and non-isothermal decomposition behaviours is presented. For double-base propellant composed of 56±1wt% of nitrocellulose (NC), 27±0.5wt% of nitroglycerine (NG), 8.15±0.15wt% of dinitrotoluene (DNT), 2.5±0.1wt% of methyl centralite, 5.0±0.15wt% of catalyst and 1.0±0.1wt% of other, the values ofτ of 49.4 years at 40℃, of TSADT of 151.35℃ and of Tb of 163.01℃ were obtained.
