Two Novel Correlations for Prediction of Electric Spark Sensitivity of Nitramines Based on the Experimental Data of the New Instrument.

This paper describes two novel simple methods for assessment of the electric spark sensitivity of cyclic and acyclic nitramines based on the new instrument marked as ESZ KTTV, which gives more reliable results than previous old system marked as RDAD. The first model uses elemental composition and a correcting function that increases the predicted results based on elemental composition. The measurements of the ESZ KTTV and the RDAD instruments revealed that the relationship is not unequivocal. Thus, the second method can convert the reported data based on the RDAD system to the ESZ KTTV instrument. Since most of the available predictive methods are based on the RDAD instrument, the second correlation is used for conversion of the predicted results based on the RDAD to the ESZ KTTV data. For 16 nitramines where both experimental values of the RDAD and the ESZ KTTV instruments were available, the values of root‐mean‐square deviation (RMSD) for the first and second models are 0.0359 and 0.0596 J, respectively. Thus, due to larger uncertainty in the experimental values of the old RDAD system, the reliability of the second model is less than the first one. [ABSTRACT FROM AUTHOR]
