IEC 61000-4-3 is a standards publication covering electromagnetic compatibility (EMC) testing and measuring techniques for radiated electromagnetic field immunity testing. From time to time, changes are made to test standards to address shortcomings, improve testing methods, react or respond to industry changes, and to establish a more controlled and repeatable test process.
