SSR's conforming to this specification are intended for use in communication, radar, digital control, and other electronic systems. Their principle areas of application are for aircraft, missiles, spacecraft, shipboard, and ground-support equipment. SSR's covered by this specification shall be able to operate satisfactorily in systems under the following demanding conditions: operating temperature range of −55°C to +125°C, 20 g's to 100 g's of vibration, 50 g's to 1500 g's of shock, up to 5000 g's of acceleration, and have reduced susceptibility to corrosion in salt water environments. These requirements are verified under a qualification system.

CAUTION: Users are cautioned to ensure that temperature limitations, transient voltages and momentary current overloads do not exceed the applicable parameters of a SSR proposed for a specific application. During high voltage testing, due caution should be exercised to avoid damage. Polarity, when applicable, should be observed. Due to the use of nonlinear-response assembly parts and the inherent difference between electromechanical and SSR's, output impedance values for like rated electromechanical relays and SSR's are not necessarily the same.
