TNT EQUIVALENCE, BERTHELOT THEORY AND THE TRAUZL LEAD BLOCK TEST
Abstract
An experimental measure of explosive performance is the Trauzl Lead Block Test. This paper assesses Trauzl, examining results against detonation parameters, including TNT Equivalence (TNTe) and Berthelot theory, attempting to find correlations. Power Index is shown to fit Trauzl, with a linear correlation, zero intercept and a near unity gradient, with an error of 4%. Trauzl is shown to be a good measure of the effectiveness of Explosive Power (EP). The Heat of Detonation (Q) and TNTe Q have a weak correlation with the Trauzl. Berthelot theory is simplified, becoming a product of Heat of Detonation and Volume of gases, nearly identical to Power Index. Berthelot is shown as related to Explosive Power (EP). Without correction, Berthelot is not recommended, since the gradient with Trauzl is 10% high and theoretical comparison with TNT is 12% high. Berthelot and Power Index have linear correlations with Trauzl, with an identical Goodness of Fit.
