This generic specification applies to electromechanical non-specified-time all-or-nothing relays of assessed quality. In order to permit assessment of the quality of electromechanical all-or-nothing relays, this specification contains the definition of procedures to be followed for qualification approval and quality conformance inspection. Within the IECQ quality assessment system, this generic specification, together with the relevant sectional and detail specifications, is used for relay qualification approval (third-party assessment by independent certification bodies). Approved relays will be granted an IECQ Certificate of Approval authorizing the use of the IECQ Mark of Approval. In addition, this specification can be used outside the IECQ quality assessment system for both first-party assessment (manufacturer's declaration) and second-party assessment (customer certification), as applicable. However, in these cases, relays can neither be granted IECQ approval nor can they be marked with the IECQ mark of approval.
