EN 61000-4-3 specifies the immunity requirements of electrical and electronic equipment to radiated electromagnetic energy. It establishes test levels and procedures for evaluating the equipment's immunity to radiated RF electromagnetic fields. The objective of this standard is to provide a common reference for assessing the immunity of equipment against these disturbances. It outlines a consistent method to test and evaluate the protection of equipment or systems from RF electromagnetic fields originating from various sources, including digital radiotelephones and other RF-emitting devices. This standard holds the status of a basic EMC publication.
