Establishes test and measurement procedures for electromechanical all or nothing relays within the scope of the I E C. Covers basic considerations which are common to all types of relays, Electrical Relays, and is of particular interest for all or nothing relays of assessed quality. Supplementary requirements may be necessitated by specific designs or application.
