WebThe most common method to analyze this data is called the “Bruceton Staircase” method. A number of samples are used to bracket the pass/fail energy level. Then a series of 20 impacts are conducted. If a test sample passes, the drop height is increased by one unit. If a test sample fails, the drop height is decreased by one unit. The results ... WebInitiation is determined, and analyzed by the Bruceton analysis or Neyer d-optimal test. ... Gas detection by infrared sampling analysis is also possible. This test simulates potential initiation of explosive that may be caught in mechanical parts, which could apply a pinch or sliding load on the explosive. Solids, liquids, or powders can be ... WebThe two most common sensitivity test and analysis methods are the Bruceton analysis and Neyer d-optimal test. These methods allow the user to determine the 50% initiation level (the distance at which 50% of the samples will "go"), and a standard deviation. Impact testing may also be performed with liquid samples confined in special cells. di meaning in chemistry

WebMar 8, 2024 · The Neyer-d optimal test was described by Barry T. Neyer in 1994. This method has replaced the earlier Bruceton analysis or "Up and Down Test" that was devised by Dixon and Mood in 1948 to allow computation with pencil and paper. Samples are tested at various stimulus levels, and the results (response or no response) noted. WebBruceton analysis has an advantage over the modern techniques being very simple to implement and analyze - as it was designed to be performed without a computer.
