Abstract:
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 detonating 22.5 ounces of lead azide in the Manual Explosives Transport Vehicle (METV). The METV is used to transport 18 1 -oz. containers of lead azide in a shielded container. The spherical barricade shields operators from the explosives while transporting the explosives in the plant. A maximum credible incident (MCI) was defined by LSAAP as a detonation of 22.5 ounces of lead azide. Based on this criteria, two blast pressure gages were placed at the loading door of the barricade, and the other at the side of the transporter. Thermal flux gages were also placed at the same positions as the blast overpressure gages. The test (continued on back) charge was functioned, then the blast pressure and thermal flux recorded. Blast overpressure levels were too low in amplitude to record. Thermal flux radiation was also too low to record. As a result, the METV met the test requirements of MIL-STD-398, Military Standard Shields, Operational for Ammunition Operations, Criteria for Design of and Tests for Acceptance.
