An assessment method of reliability of initiating devices based on information measure equivalency

A new method for assessing the reliability of initiating devices based on test information measure equivalency was put forward. According to the principle that more information on reliability from tests on the stress level of low reliability could be gotten over the stress level of high reliability, only one tenth of samples needed by classical method were used to estimate the reliability of 0.999 through test on the stress level of low reliability under the condition of the equivalent information measure obtained by tests between low reliability and high reliability. The assessment result of the new method is consistent with that of the large sample assessment method. The verification test result shows that the new method is feasible for reliability assessment of initiating devices.
