Validity of variables-attributes assessment method for reliability of initiating explosive devices

By Monte Carlo, the equivalence between GJB376 method and variables-attributes assessment method was studied. According to reliability assessment rule, it is required that the maximum error of receptance between two methods is less than 1%. Twenty kinds of qualified and unqualified products assumed artificially were assessed with variables-attributes method and run-down method respectively. The conclusions from two methods are consistent. Results show that variables-attributes assessment method is equivalent to GJB376 method and the variables-attributes method is feasible for assessing high reliability of initiating explosive devices with small samples.
