Modifications to the Fast Variable Confinement Cook-Off Test (VCCT) at Picatinny Arsenal

Abstract

The response of an energetic material when heated in confinement is critical safety knowledge for explosives and munitions developers. Cook-off experiments are required for energetic material qualification, hazard classification, and Insensitive Munitions (IM) assessment. The variable confinement cook-off test (VCCT) is a sub-scale test used to assess an explosives confined response to heating. There are standard procedures in place to perform VCCT in a slow or fast cook-off configuration, with heating rates ranging from 3.3 C/hr for the slow VCCT to 2 to 3 C/sec for the fast VCCT. Due to obsolescence of the mica band heaters typically used for VCCT, a new approach to the fast VCCT was needed. This report details revised fast VCCT procedures at the U.S. Army Combat Capabilities Development Command (DEVCOM) Armaments Center (AC) Explosive Development Facility, Picatinny Arsenal, NJ, and provides test data for a common combined effects explosive fill, PAX-30.
