The U.S. Army Defense Ammunition Center and School USADACS was tasked by Lone Star Army Ammunition Plant LSAAP, Texarkana, TX to provide MIL- STD-398, Military Standard Shields, Operational for Ammunition Operations, Criteria for Design of and Tests for Acceptance, instrumentation services for measuring blast overpressure and thermal flux produced by several charges of Class 3 black powder constrained to function high order. Two amounts of powder were used, 1.25 and 1.875 pounds. Blast overpressure and thermal flux gages were placed at the operators position and at a possible transient position around the barricade. All test charges resulted in blast overpressure in excess of 5.0 psi reflected, schrapnel production. Thermal flux was at a minimum. As a result, the barricade for the M82 primer did not satisfy the requirements of MIL-STD- 398, Military Standard Shields, Operational for Ammunition Operations, Criteria for Design of and Tests for Acceptance, or the requirements of AMCR 385-100 for energetic materiel.
