MIL-STD-398 Test of Net Weight Filling System Barricade

摘要

The U.S. Army Defense Ammunition Center and School (USADACS) was tasked by LoneStar 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 igniting 6.25 pounds of M10 propellant in the net weight filling system barricade. This amount of explosives duplicated the maximum amount, plus a 25 percent safety overload, which is outlined for use in actual production. A maximum credible incident (MCI) was defined by LSAAP as a detonation of 6.25 pounds of M10 propellant. Based on this criteria, two blast pressure gages were placed at the loading door of the barricade, and the other at the filling position. Thermal flux gages were also placed at the same positions as the blast overpressure gages. A third thermal flux gage was placed at the side facing the dump chute. (continued on back) The test 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 net weight filling system met the test requirements of MIL-STD-398, Military Standard Shields, Operational for Ammunition Operations, Criteria for Design of and Tests for Acceptance.
