Abstract : The U.S. Army Defense Ammunition Center and School (USADACS) was tasked by Lone Star Army Ammunition Plant (LSAAP), Texarkana, TX to provide MHS'ID-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 of the prototype Explosive Containment Device (ECD) when 1.25 ounces of lead azide is functioned. The 1.25 ounces of lead azide represent the maximum amount of explosive material plus a 25 percent overload for a safety factor. As a result of functioning the lead azide, the ECD did not contain the explosion because the closure door was damaged which allowed the incident blast overpressure to register 6.31 psi. This overpressure exceeded the 2.5 psi limit required in MIL-STD-398, Military Standard Shields, Operational for Ammunition Operations, Criteria for Design of and Tests for Acceptance. As a result, the ECD did not meet the test requirements and is not suitable for containing initiating explosives.
