This specification covers the general requirements for electromagnetic, hermetically sealed relays for use in electronic and communication-type equipment (see 6.1). These relays are designed to operate over the full range from low level to power switching with contact ratings up to 5 amperes alternating current (ac) or direct current (dc). The failure rate level is established at a confidence level of 90 percent for qualification and 60 percent for maintenance of qualification based on 100,000 cycles at +125°C under the rated load conditions specified herein. CAUTION: The use of any coil voltage less than the rated coil voltage will compromise the operation of the relay. CAUTION: Pick-up, hold, and dropout voltages are for test purposes only and are not to be used as design criteria. For additional application and caution information, see 6.1.
