This standard specifies the terms and definitions used for all-or-nothing electrical relays; recommended values; maximum permissible temperature; accuracy of time limits; mechanical and electrical requirements to be met by relays; applicable test methods; data and markings. This standard applies to all-or-nothing electrical relays. This standard applies only to newly manufactured relays with contacts in the output circuit. This standard applies to relays used in many electrical technical fields covered by IEC. For special application areas, the scope of application of this standard can be expanded with the help of special standards. This standard does not include requirements for relays for telephone and telegraph equipment. Standards applicable to this type and similar relays are under consideration. This standard does not apply to relays used in railway signaling and blocking systems.
