Analysis of Overall Standard Deviation of Thermal Safety Criteria for Small-scale Energetic Materials

Twenty expressions describing the overall standard deviation(σ) of thermal safety criteria of small-scale energetic materials were presented.The values of σ and relative standard deviation of thermal safety criteria for 1,1′-dimethyl-5,5′-azotelrazol monohydrote,3-nitro-1,2,4-triazol-5-one,bis(2,2,2-trinitroethyl) formal and double-base propellant composed(56±1) wt% of NC,(27±0.5) wt% of NG,(8.5±0.15) wt% of DNT,(2.5±0.1) wt% of methyl centralite,(5.0±0.15) wt% of catalyts and(1.0±0.1) wt% of other were reported.
