This part of IEC 62489<\/span> <\/span> applies to audio-frequency induction-loop systems for assisted hearing. It may also be applied to such systems used for other purposes, as far as it is applicable. The standard is intended for assessment of human exposure to low-frequency magnetic fields produced by the system, by calculation and by in-situ testing.<\/p>\n

This standard does not deal with other aspects of safety, for which IEC 60065<\/span> <\/span> applies, or with EMC.<\/p>\n
