Deficiency Investigation of the 1-Lb. TNT Demolition Block Charge

摘要

At Camp Clark in Nevada, Missouri, in August 1965, 100 1-lb. TNT Demolition Block Charges (Lot SOD 600-1) failed to function. The circumstance causing this malfunction was investigated by the Ammunition Engineering Directorate's Ammunition Engineering Laboratory. It was determined that these TNT charges failed to detonate because of insufficient energy from the initiating devices. To detonate these 1-lb. TNT block charges, only four types of blasting caps must be used -- M6 and M7 Blasting Caps (military) and JI and JII (commercial); if Primacord is used, the exact procedure in FM 5-25 must be followed: three snug turns around the block. Release of the lot was recommended based on these findings. (Author)
