BS EN 62226 discusses exposure to electric or magnetic fields in the low and intermediate.
BS EN 62226-2-1 belongs to BS EN 62226 multi-series and discusses methods for calculating the current density and internal electric field induced in the human body.
BS EN 62226-2-1 is a part of IEC 62226 that introduces the coupling factor K, to enable exposure assessment for complex exposure situations, such as a non-uniform magnetic field or perturbed electric field. The coupling factor K has different physical interpretations depending on whether it relates to electric or magnetic field exposure.
BS EN 62226-2-1 on electric or magnetic fields in the low and intermediate frequency range is useful for:
BS EN 62226-2-1 applies to the frequency range for which the exposure limits are based on the induction of voltages or currents in the human body when exposed to electric and magnetic fields. This frequency range covers the low and intermediate frequencies, up to 100 kHz.
BS EN 62226-2-1 defines in more detail this coupling factor K, for the case of simple models of the human body, exposed to non-uniform magnetic fields. It is thus called the “coupling factor for non-uniform magnetic field”.
All the calculations developed in BS EN 62226-2-1 use the low-frequency approximation in which displacement currents are neglected. This approximation has been validated in the low-frequency range in the human body.
