Electromagnetic compatibility (EMC) - Product standard for measuring relays and protection equipment

The objective of the standard is to specify limits and test methods for apparatus in relation to electromagnetic emissions which may cause interference in other apparatus. These emission limits represent essential electromagnetic compatibility requirements and have been selected to ensure that the disturbances generated by the apparatus, operated normally at industrial locations do not exceed a level which could prevent other apparatus from operating as intended. Test requirements are specified for the enclosure and power supply ports. Note: in special cases, for instance when highly susceptible devices are being used in proximity to the apparatus, additional mitigation measures may have to be employed.
