How the IEC is organized for EMC
The first work in the EMC field can be traced back to when the International Special Committee on Radio Interference (CISPR, now part of the IEC) was established in 1934. But today the scope of EMC work has expanded to such an extent that the IEC organizes it among several committees. Many of these have working relationships or official liaisons with outside groups ranging from professional associations to national, regional and international organizations.
The diagram below outlines from an IEC perspective how these groups co-operate.
