Abstract
TNT equivalency is a standard used to measure and quantify the effects of energetic materials. Using these equivalencies, the safety factors for minimum distances and storage of explosives are determined. Having a known TNT equivalence of energetic materials also helps estimate potential blast damage and risks for individuals. The TNT equivalencies for numerous energetic materials, such as binaries, have no published values, but are regularly used in industry, military, and research testing. To determine TNT equivalence, three tests will be performed: 1) a plate dent test, 2) air blast tests to measure air overpressure and calculate impulse, and 3) velocity of detonation test. The data collection method will be validated by also testing commonly published explosive equivalencies, namely Composition B. New values for Helix, Texpak, Tannerite, dynamite, and Kinepak will be determined. This research will produce TNT equivalency values for commonly used explosives and provided recommendations for an inexpensive and repeatable method of determining TNT equivalence. These results aim to provide helpful insight for law enforcement and the military into the effects of different energetic materials. Standardizing these TNT equivalency values for energetic materials will ensure safe procedures that mitigate the potential risks and blast damage for the military and law enforcement when handling, storing, or detonating explosives.
