TNT Equivalency of Ball Powder WC844

Abstract : Peak side-on blast overpressure and scaled positive impulse have been measured for ball powder WC844 using configurations that simulate in-plant processing and shipping containers. Quantities of 22.7, 36.3, 45.4, and 72.6 kg were tested in cylindrical shipping containers and in simulated sections of dryer beds. High explosive equivalency values for each test series were obtained as a function of scaled distance by comparison to known pressure and impulse characteristics for TNT surface bursts. Equivalencies were found to depend significantly on geometry.
