Effects of Charge Density on the Shock Sensitivity of TNT

Shock sensitivities of TNT charges having different densities , obtained through casting or pressing were measured . Making use of the card gap test , electronic method , pressure - resistor method and high speed streat camera technique , the card - gap thickniss , initination pressure and depth for 50% detonation were obtained . The results show that the methods adopted in explosive charging and the charge density have marked influnce on the shock sensitivity .
