摘要

The sensitivity of explosives to various initiating events has a shape of sigmoidal curve. In standard sensitivity tests one point on this curve is sought most often the 50% initiation probability level. The most common method for its determination is the up-and-down method. The whole sensitivity curve can be obtained by conducting large number of trials at all levels or more effectively by probit analysis. The usage of probit analysis, improvement the precision of the results and comparison with the up-and-down method is demonstrated on the example of determination of sensitivity to friction.
