Abstract:

The report documents findings on the non-operating reliability of relays. The study covers 2218 million part-hours. The best sources show a storage failure rate of 1.3 fit failures per billion hours with a one sided 90 percent confidence limit of 5.0 fit. Elements of relay design and of the processes at the contacts are reviewed. The possibilities of solid state and saturable core alternatives are described. Recommendations include periodic test and inclusion of oxygen in the fill gas. The objective of this program is the development of non-operating storage reliability prediction and assurance techniques for missile materiel.
