适用范围：This part of the IEC 62489 series applies to the components of audio-frequency inductionloopsystems for assisted hearing. It may also be applied to such systems used for otherpurposes, as far as it is applicable. This standard is intended to encourage accurate anduniform presentation of manufacturers' specifications, which can be verified by standardizedmethods 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 dealwith EMC (Electromagnetic compatibility) and EMF (Electromagnetic fields, in the context ofhuman exposure).
