Two IEC technical committees are devoted full-time to EMC work, although nearly 40 others have some involvement with EMC as part of their scope. The two full-time committees are TC77, Electromagnetic compatibility between equipment including networks, and the International Special Committee on Radio Interference or CISPR, which is the acronym for its French title. There is also the Advisory Committee on EMC (ACEC), which is expected to prevent the development of conflicting standards.
