用于评估人体暴露于头部和身体附近无线设备射频电磁场的比吸收率到吸收功率密度的转换方法.6GHz到10GHz的频率范围

[中文适用范围]： 本文件规定了一种将特定吸收率（SAR）转换为吸收功率密度（APD）的方法，用于评估无线设备在接近头部和人体时产生的射频电磁场（EMF）对人体的暴露。该转换方法基于SAR值，旨在为手持、穿戴式或任何其他能在接近人类头部或人体处操作的射频传输通信设备，在6 GHz至10 GHz频率范围内，为绝大多数人群的使用场景提供保守且可重复的吸收功率密度评估值。该方法适用于评估是否符合适用的吸收功率密度或表皮功率密度限值（如ICNIRP 2020指南和IEEE Std C95.1-2019中定义的标准）。该方法不适用于植入体内的设备或物体的电磁场评估。 [外文原描述]： IEC PAS 63446:2022, a Publicly Available Specification, provides the method to conservatively evaluate the area averaged electromagnetic (EM) power density entering the human body, i.e. the absorbed power density (APD), for communication devices intended to be used at a position near the human head or body, or mounted on the body, combined with other transmitters within a product, or embedded in garments. The device categories covered include but are not limited to mobile telephones, radio transmitters in personal computers, and desktop and laptop devices. The applicable frequency range is from 6 GHz to 10 GHz. This document specifies: conversion of the psSAR to the psAPD (Clause 6); uncertainty estimation (Clause 7); reporting requirements (Clause 8); methods of validation and system check (Annex C)
