Blast wave parameters and TNT equivalency of improvised explosives:erythritol tetranitrate
The knowledge of blast wave parameters of detonating explosive is important for evaluation of protective measures, modeling and post blast analysis.The relevant data are quite common for military explosives, but much less common for the improvised ones.In this contribution we present experimental blast wave parameters of small scale bare charges of erythritol tetranitrate (low density charges were powdered and taped-d =0.80 g.cm3, high density charges were cast-d =1.70 g.cm-3), their comparison to small scale charges of TNT and calculation of TNT equivalency based on maximum overpressure and impulse of positive phase of the blast wave.The maximum incident overpressure and incident impulse of the positive phase were not influenced by the density of the charges.Average TNT equivalency from incident overpressures was 160%, and from the impulse of the positive phase of the blast wave was 171%.
