TNT Equivalency of Composition A5

Abstract

Peak blast overpressure and scaled positive blast impulse have been measured for Composition A5 using configurations that simulate bulk handling of material during processing and shipment. Quantities of 11.34, 22.7, and 27.22 kg (25, 50, and 60 lb, respectively) were tested in orthorhombic fiberboard boxes, and 68.04 kg (150 lb) were detonated in cylindrical fiber containers. High-explosive equivalency values for each test series were obtained as a function of scaled distance by comparison to known pressure, arrival time and impulse characteristics for hemispherical TNT surface bursts. The equivalencies were found to depend significantly on scaled distance with higher values (140 to 500%) at the extremes within the range from 1.19 to 15.87 m/cube rt. (Kg) ((3 to 40 ft/cube rt. (lb)), respectively. Equivalencies as low as 100% were obtained at intermediate distances. Within experimental error, both peak overpressure and positive impulse scaled as a function of charge weight for all quantities tested in the orthorhomic configuration.
