标准范围

IEC 62489-1:20 10适用于用于辅助听力的音频感应回路系统的组件。只要适用，它也可以应用于用于其他目的的此类系统。本标准旨在鼓励准确和统一地呈现制造商的规格，这些规格可以通过标准化的测量方法进行验证。它用于型式测试。考虑的组成部分如下:-放大器；-麦克风；-其他部件，例如回放设备。IEC 62489-1:20 10不涉及安全，IEC 60065适用于此。它也不涉及EMC（电磁兼容性）和EMF（人类暴露背景下的电磁场）。

IEC 62489-1:2010 applies to the components of 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. 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.
IEC 62489-1:2010 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).
