Combination statistical design for sensitivity testing

Technical Report ·
OSTI ID:5266955
The Bureau of Mines compared the up-and-down method with factorial designs to determine if shorter and, therefore, less costly trial sequences could be used. Although sequences of 50 trials are usually recommended, sequences of 20 trials were arbitrarily chosen for the experiments with permissible coal mine explosives described in this report. These explosives were fired from a cannon pointed into a flammable natural gas-air atmosphere at the Bureau of Mines Explosives Research Center gallery to ascertain their safety properties. The investigation demonstrated that the shorter sequences led to useful conclusions with a reduction in cost of the experimental program.
