IEC TR 63377:2022描述了评估在30 MHz至300 GHz频率范围内工作的辐射无线功率传输（WPT）系统是否符合人体暴露电磁指南（电磁场强度、比吸收率（SAR）和功率密度）的评估方法。本文件包括但不限于将发射器发射的电磁能聚焦到接收器周围区域的系统，例如通过窄波束形成系统、宽波束系统和空间封闭系统。没有变送器的实施，例如，从环境中获取能量的应用，不包括在本文件的范围内。

IEC TR 63377:2022 describes assessment methods to evaluate the compliance of radiative wireless power transfer (WPT) systems operating in the frequency range from 30 MHz to 300 GHz with electromagnetic guidelines on human exposure (electromagnetic field strength, specific absorption rate (SAR), and power density). This document includes but is not limited to systems that focus the electromagnetic energy emitted by the transmitter to regions surrounding the receiver, for example, by narrow beam-forming systems, wide-beam systems and spatially closed systems. Implementations without transmitter, for example, applications that harvest energy from the environment, are not included in the scope of this document.
