This part of IEC 62226 provides means for demonstrating compliance with the basic restrictions on human exposure to low and intermediate frequency electric and magnetic fields specified in exposure standards or guidelines such as those produced by IEEE and ICNIRP.
The object of IEC 62226 is
- to propose a more realistic approach to the modelling of the human exposure to low frequency electric and magnetic fields, using a set of models of growing complexity for the field emission source, or the human body or both;
- to propose standardised values for the electrical parameters of organs in human body: electrical conductivity and permittivity and their variation with the frequency.
The present basic standard does not aim at replacing the definitions and procedures specified in exposure standards or guidelines, such as those produced by IEEE or ICNIRP, but aims at providing additional procedures with a view to allowing compliance assessment with these documents.
The present basic standard provides means for demonstrating compliance with the basic restrictions without having to go to the sophisticated models. Nevertheless, when the exposure conditions are well characterized (such as in product standards, for example) and when results from such models are available, they can be used for demonstrating compliance with EMF standards or guidelines.
NOTE 1 Examples of use of such sophisticated models can be found in the IEC Trend Technology Assessment 1.
