IEC Issues Standard on Human Exposure to EM Fields from Household Appliances

Standards Alert: IEC 6223 Ed. 1.0

 

The International Electrotechnical Commission (IEC) has published IEC 6223 Ed. 1.0 entitled "Measurement Methods for electromagnetic fields of household appliances and similar apparatus with regard to human exposure." This standard deals with electromagnetic fields up to 300 GHz and defines methods for evaluating field strength and magnetic flux density around household and similar electrical appliances, including the conditions during testing as well as measuring distances and positions.

Appliances may incorporate motors, heating elements or their combination, may contain electric or electronic circuitry, and may be powered by the mains, by batteries, or by any electrical power source. Such apparatus includes household electrical appliances, electric tools, and electric toys. Appliances not intended for normal household use but which may be approached by the public, or may be used by laymen are within the scope of this standard.

The standard includes specific elements for assessing human exposure. Specific elements defined include sensor, measuring methods, operating mode for appliance under test, and measuring distance and position. The measurement methods specified are valid from 10 Hz to 400 kHz. In the frequency range above 400 kHz and below 10 Hz, appliances within the scope of this standard are deemed to comply without testing unless otherwise specified in the IEC 60335 series. For more information, go the the IEC website.

Testing, research, and appropriate exposure levels regarding human exposure to EMFs is a subject of ongoing controversy. Learn more about your colleagues experiences in this area by visiting the Testing Community Forums.
