Bruceton method
WebThe method to analyze this test data is called the "Bruceton Staircase" method. A series of 20 to 25 impacts are conducted. If a test specimen passes, the drop weight is increased … Webcommonly called the Bruceton Staircase Method, or the Up-and-Down Method(1).3 Testing is concentrated near the mean, reducing the number of specimens required to obtain a reasonably precise estimate of the impact resistance. 4.4 This test method permits the use of different striker diameters and specimen support plate geometries to obtain

WebMar 29, 2012 · 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 result was a 50% probability of reaction, useful for ranking the comparative responses of various explosives ... WebMar 12, 2012 · Sensitivity tests are often used to estimate the parameters associated with latent continuous variables that cannot be measured. For example, each explosive specimen has a threshold. The specimen will detonate if and only if an applied shock exceeds this value. Since there is no way to determine the threshold of an individual, …
WebSep 15, 2002 · The three priming compositions were pressed into the charge holder of the EEDs in order to evaluate the dc sensitivity by the Bruceton method [3]. The up-and-down procedure, sometime called the Bruceton method, is one of a class of procedures. In the up-and-down procedure only one object is tested at a time. 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…
