Measurement methods for electromagnetic fields of household appliances and similar apparatus with regard to human exposure. IEC and EN testing deals with electromagnetic fields up to GHz and defines methods for evaluating the electric 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 other electrical power source. Appliances include such equipment as household electrical appliances, electric tools and electric toys. Appliances not intended for normal household use but which nevertheless may be approached by the public, or may be used by laymen, are within the Scope: of this standard. Abnormal operation of the appliances is not taken into consideration.
The measurement methods specified are valid from 10 Hz to kHz. In the frequency range above kHz and below 10 Hz appliances in the Scope: of this standard are deemed to comply without testing unless otherwise specified in IEC series.

In general, the suppliers should ensure that their household electrical products conform to the latest requirements of the applicable International Electrotechnical Commission IEC safety standards or other equivalent international standards such as European Community EU safety standards unless otherwise stated in the Electrical Products Safety Regulation. In addition, the electromagnetic field EMF generated by household electrical products shall not produce radiation which is likely to cause danger to the general public. Agreement on the implementation time frame has been reached. The details are shown in the table below:. According to the requirements of IEC , this standard does not apply to audio and video electrical products, information technology equipment as well as luminaires. The EMF generated by these products must comply with the relevant requirements in the following safety standards:. IEC Measurement methods for electromagnetic fields of household appliances and similar apparatus with regard to human exposure.
IEC 62233 Testing
IEC describes measurement methods for determining electric field strength and magnetic flux density for household and other electrical appliances. The standard covers electromagnetic fields from 0 to GHz. Along with test methods, IEC describes ideal testing conditions as well as recommended measuring distances and positioning. Methods specified in this standard are valid over a frequency range of 10 Hz to kHz; frequencies below 10 Hz and above kHz are regarded as complaint without testing, unless called out in IEC IEC is the latest version of the standard.
