Webusing the “Bruceton Staircase” method. 20 samples will be tested for either pass or fail results. The initial height of the test will be 125mm. Although a wheelbarrow will likely experience a greater impact height than 125mm, this value was determined based upon the fact that an impact disk will have a significantly thinner thickness than ... WebThe Bruceton Staircase method [7] was used to determine the thickness and standard deviation in the thickness of an attenuator material required to give a 50% probability of initiation for the acceptor explosive. The procedure requires a number of initial experiments to establish the approximate number of attenuator discs ...

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 … WebApr 1, 2015 · Procedure B, Bruceton Staircase Method—This procedure is used to determine the mean failure height and the standard deviation of the distribution. The values stated in SI units are to be regarded as standard. The inch-pound units given in parentheses are for information only.

WebTypically, an odd number of samples are used for the Bruceton Staircase technique to obtain several data points around the breakage point. Innovate With Us. EMAILinfo@pti … WebIn terms of layer adhesion for multilayer packages, Valspar says its material has resisted delamination from up to 6 ft in the Bruceton staircase drop test. Valspar introduced the packaging world to ValOR at the Nova-Pack event (Feb. 5-7, Amelia Island, FL) earlier this year, presenting three grades: ActivBloc 100, Activ100, and Bloc100. WebBruceton Staircase is a method that gives the most precise way of analyzing this data. As many as 20 specimens are used to bracket the pass/fail energy grade. Gradually the distance is increased, and as the weight drops, the failure point is determined. Specimens, up to 20, are generally used for known estimated mean-failure height. css 泡泡特效
