EMC Standards Work

RSGB has been represented on many National & International Standards Committees

Currently we are active Participants in

GEL210/11 Product EMC EN55022 IT Equipment Radio disturbance, EN55024 IT Equipment Immunity Characteristics, EN55032 Multimedia Equipment emission requirements, EN50561 PLT devices

GEL210/12 Basic generic and LF EMC a plethora of standards on lighting,wiring, power systems, for domestic and industrial environments

CISPR/F Interference from Household appliances

We also keep a monitoring watch on

EMC Policy GEL 210, PEL205 Mains Signalling, BSI committee on Smart Grid.

If you would like to help in these matters please contact the RSGB EMC Committee
