2-Dimethylaminoethyl azide (DMAZ) is a good replacement for the hydrazine family in space industries. In this article, the accelerated ageing test method was applied for predicting the shelf life of DMAZ. The effective parameters on the storage of the fuel were temperature, the type of gas atmosphere with its pressure over the liquid fuel, and moisture. Appropriate conditions for DMAZ storage were N2 at a pressure of 3 bar and a moisture content of 0.05 wt.%. The sigmoid form of the decomposition curves obtained revealed that the decomposition reaction is autocatalytic. Modelling of the decomposition rate showed that the shelf life of DMAZ was 7.73 years at 25 °C.
