One-Liter Test: A Mid-Scale Safety Characterization Test For Melt-Castable Explosives.
Abstract
The One-Liter test was developed as a mid-scale safety characterization test specifically for use with melt-castable explosives. It is a one-dimensional test carried out under relatively unconfined conditions that are similar to those encountered in melt casting operations. The test allows the researcher to assess the response of the explosive to a controlled thermal stimulus under laboratory-like conditions and, more importantly, to determine its critical temperature. The latter is defined as the lowest constant surface temperature at which a material of a specific size, shape and composition can self-heat catastrophically. This test allows one to validate kinetic and thermal parameters determined by standard small-scale laboratory experiments. These parameters are necessary to predict the critical temperatures associated with large scale melt cast operations. The experimental critical temperature of the explosive used in this report to demonstrate the use of the One-Liter test falls in the temperature range 152-155 deg C. Critical temperatures for large-scale melt casting operations up to 100 gallons are predicted.
