BS EN 62489-1:2010 PDF

Scope: This part of the IEC 62489 series applies to the components of audio-frequency inductionloop systems for assisted hearing. It may also be applied to such systems used for other purposes, as far as it is applicable. This standard is intended to encourage accurate and uniform presentation of manufacturers' specifications, which can be verified by standardized methods of measurement. It is intended for type testing. The components considered are the following: – amplifiers; – microphones; – other components, such as playback equipment. This standard does not deal with safety, for which IEC 60065 applies. It also does not deal with EMC (Electromagnetic compatibility) and EMF (Electromagnetic fields, in the context of human exposure).
