Abstract
The design margin technique is applied to the evaluation of poststorage reliability of nine high quality gyro assemblies. Compared to standard reliability evaluation based on attribute tests (pass-fail), the technique is shown to yield more sensitive measures of reliability and narrower confidence intervals for a given sample size. Advantages of the design margin technique in measuring performance degradation during storage and in permitting experience on an existing design to be applied to the development of an improved model are pointed out.
