VARICOMP. A METHOD FOR DETERMINING DETONATION-TRANSFER PROBABILITIES

Varicomp is a method for determining the detonation-transfer probabilities of an explosive train by substitution of explosives of varied sensitivities or energies for the design explosive. These substituted--Varicomp- -explosives whose response or output probability distribution functions have been calibrated relative to the design explosive are used to measure the explosive drive inherent in the design system. Methods of calibrating explosives and carrying out Varicomp performance tests are given along with statistical procedures for combining performance test and calibration data. These procedures are the basis for predictions, at high confidence levels, of very high reliability or safety of an explosive system based on a relatively small number of tests carried out on the explosive system. Computational aids and a number of illustrative examples are included.
