Relays conforming to this specification are intended for use in electronic and communication equipment. Their principal areas of application are for ground-support electronic and communication equipment. Relays covered by this specification operate satisfactorily in systems under the following demanding conditions: operating temperature range of -65 degrees C to +125 degrees C, 20g's to 100 g's of vibration, 50 g's to 1500 g's of shock, and have reduced susceptibility to corrosion in salt water environments. This does not preclude the use of these relays in other military applications.
