This standard provides procedures for inspecting and testing electromagnetic relays for the applicable mechanical, electrical, and environmental requirements of individual relay specifications. The standard is intended for relays that perform general switching functions in military and commercial systems: it is not applicable to the following electromagnetic switching devices, some of which are covered by other standards:

Choppers

Circuit breakers

Contactors Motor-driven time-delay relays

Relays associated with electric power apparatus

Stepping relays

Pneumatic and hydraulic relays

Reed switch relays (EIA Standard RS-436)

Thermal relays

Solid state relays (EIA Standard RS-443)

For the definition of the various relay terms cited in this publication refer to:

(1) ANSI C83.16-1971 American National Standard Definitions and Terminology for Relays for Electronic Equipment.

(2) ANSI C42.0 American National Standard Definitions for Electrical Terms.
