Abstract This paper mainly discusses one research method of the storage reliability for the aerospace electromagnetic relays. The failure mechanism of aerospace electromagnetic relays during the storage period was analyzed. The constant temperature stress accelerated storage life test was carried out according to the test plan provided. The part of test results and the failure analysis on the typical failure samples were illustrated. At last, the grey dynamic model was used for estimating the storage life of relays at the different temperature stresses. It is indicated that the above method can be used for forecasting the storage life of the aerospace electromagnetic relays.
