Bruceton sensitivity test

WebJul 29, 2011 · Gap testing is the ubiquitous test to statistically quantify shock sensitivity, but it exists in many forms. We used the LANL small scale gap test for our studies more » because it has the advantage of requiring very little material (less than 9g per test) and can be easily instrumented. A Bruceton analysis is one way of analyzing the sensitivity of explosives as described originally by Dixon and Mood in 1948. Also known as the "Up and Down Test" or "the staircase method", a Bruceton analysis relies upon two parameters: first stimulus and step size. A stimulus is provided to the sample, and the results noted. If a positive result is noted, then the stimulus is decremented by the step size. If a negative result occurs, the stimulus is increased. The test continues with e…

WebMar 29, 2012 · In order to safely work with explosives, their sensitivity to external stimuli needs to be characterized. The Bruceton method for evaluating explosives sensitivity results has been used effectively for over six decades. This has included the skid test on the large scale, and the friction and drop weight impact tests on the small scale. The ... WebThis is called a Bruceton test when the data is analyzed by the classical up-and-down method of Dixon and Mood (1948). (Bruceton is the name of a military installation in Pennsylvania, see Mood (1998).) For parametric inference on binary data with various stimu-lus levels, this method is still actively used in Pyrotechnics Sensitivity Analysis
