BS EN 61810-7 is a British standard as a part of the IEC 61810 series that states the test and measurement procedures for electromechanical elementary relays. BS EN 61810-7 covers basic considerations which are, in general, common to all types of electromechanical elementary relays. Supplementary requirements may be necessitated by specific designs or applications.
The test and measurement procedures of BS EN 61810-7 are described as individual provisions covering a specific requirement. When combining them in a test programme, care must be taken to ensure that preceding tests do not devalue subsequent ones.
Note 1: To improve the readability of BS EN 61810-7, the term “relay” is generally used in place of “electromechanical elementary relay”.
Note 2: Requirements and tests related to the type testing of electromechanical elementary relays are contained in IEC 61810-1. For that purpose, the generally described test and measurement procedures of BS EN 61810-7 have been prescribed in a more restricted and stringent form in IEC 61810-1.
Note 3: Standards covering relays subjected to quality assessment in accordance with IECQ are compiled in the IEC 61811 series of publications.
BS EN 61810-7 on electromechanical elementary relays test procedures is useful for:
Between the control circuit and the load, the electromechanical relay serves as an interface. A relay requires only a modest amount of power to switch on, but it can control something that consumes much more. Contact resistance is substantially lower in relays. High-frequency circuits may benefit from the lower contact capacitance. Transients are less likely to turn on relays than solid-state switches.
BS EN 61810-7 provides its users with guidelines for test measures and procedures to assess the insulation resistance, the thermal resistance of the coil, thermal endurance, electrical endurance, capacitance, etc. Using BS EN 61810-7 guidelines ensures safety, protection, efficiency, and quality assurance for its users.
