本国际标准规定了通过射频（RF）发射设备对头部或身体进行功率密度（PD）的可重复和保守测量的协议和测试程序，并规定了不确定度。这些协议和程序适用于包括儿童在内的绝大多数人在使用手持和穿戴式无线通信设备时使用。这些设备可以具有单个或多个发射器或天线，并且可以在距离人类头部或身体200 mm的距离处使用其辐射部分进行操作。本标准可用于评估耳旁、面部前方、安装在身体上、与其他射频发射或非发射设备或配件（如皮带夹）结合使用或嵌入服装中的不同类型无线通信设备的PD合规性。总体适用频率范围为6 GHz至300 GHz。

This document specifies protocols and test procedures for repeatable and reproducible measurements of power density (PD) that provide conservative estimates of exposure incident to a human head or body due to radio-frequency (RF) electromagnetic field (EMF) transmitting communication devices, with a specified measurement uncertainty. These protocols and procedures apply for exposure evaluations of a significant majority of the population during the use of hand-held and body-worn RF transmitting communication devices. The methods apply for devices that can feature single or multiple transmitters or antennas, and can be operated with their radiating structure(s) at distances up to 200 mm from a human head or body. The methods of this document can be used to determine conformity with applicable maximum PD requirements of different types of RF transmitting communication devices being used in close proximity to the head and body, including if combined with other RF transmitting or nontransmitting devices or accessories (e.g. belt-clip), or embedded in garments. The overall applicable frequency range of these protocols and procedures is from 6 GHz to 300 GHz. The RF transmitting communication device categories covered in this document include but are not limited to mobile telephones, radio transmitters in personal computers, desktop and laptop devices, and multi-band and multi-antenna devices.
