Information from EMC Electromagnetic Compatibility Emission CISPR Publications 11, 14, 16, 22 Conducted Emission on Power mains Conducted Emission on Data and Signal Lines Radiated Emission M-field, E-Field Immunity Basic standards IEC 61000-4-xx Phenomena Oriented IEC International Electrical Commission Residence :Geneva (Switzerland) Members :42 country Committees :TC/SC 198 EMC within IEC TC77 Electromagnetic Compatibility The scope covers the following aspects of EMC Immunity, over the wide Frequency range. Emission, in the low frequency range(up to 9kHz) Emission in the high frequency range(over 9kHz) in co-ordination with CISPR, and disturbances not covered by CISPR. Structure of the IEC TC77 SC 77A : Low frequency disturbance SC 77B : High frequency disturbance SC 77C : Immunity to High Altitude Nuclear Electromagnetic Pulse (HA-NEMP) Not in the response of the TC77, standards on EMC for Vehicles, ships, planes, special radio and telecom systems and work which belongs to aims of CISPR.
