无线电通信基站附近用于评估人体暴露的射频场强和 SAR 的测定（第 2.0 版

[中文适用范围]： 本文件提供了确定无线电通信基站（RBS）附近射频（RF）场强和比吸收率（SAR）的方法，以评估人体暴露情况。本文件： a) 考虑有意辐射 RBS，该 RBS 使用 110 MHz 至 100 GHz 范围内的一个或多个频率在一根或多根天线上进行传输； b) 至少在 100 kHz 至 300 GHz 频率范围内考虑环境源对射频暴露的影响； c) 规定用于合规性评估应用@的射频暴露评估的方法，即： 1) 产品合规性？C 在 RBS 产品投放市场之前确定其合规边界信息； 2) 产品安装合规性？C 在产品投入使用之前确定 RBS 产品和其他相关源在可触及区域的总 RF 暴露水平； 3) 原位射频暴露评估——产品投入运行后，对 RBS 装置附近的原位射频暴露水平进行测量； d) 描述了几种射频场强和 SAR 测量和计算方法，并提供了其适用性的指导，以解决已安装的 RBS 的现场评估和基于实验室的评估； e) 描述具有足够专业水平的测量员@如何建立适合其评估目的的具体评估程序； f) 提供关于如何报告@解释和比较不同评估方法的结果以及@在评估目的需要时@根据极限值确定合理决定的指导； g) 提供了配套技术报告 IEC TR 62669 [1] 中给出的信息丰富的示例案例研究的简短描述。 [外文原描述]： IEC 62232:2017 provides methods for the determination of radio-frequency (RF) field strength and specific absorption rate (SAR) in the vicinity of radiocommunication base stations (RBS) for the purpose of evaluating human exposure. This document: - considers intentionally radiating RBS which transmit on one or more antennas using one or more frequencies in the range 110 MHz to 100 GHz; - considers the impact of ambient sources on RF exposure at least in the 100 kHz to 300 GHz frequency range; - specifies the methods to be used for RF exposure evaluation for compliance assessment applications, namely: - product compliance - determination of compliance boundary information for an RBS product before it is placed on the market; - product installation compliance - determination of the total RF exposure levels in accessible areas from an RBS product and other relevant sources before the product is put into service; - in-situ RF exposure assessment – measurement of in-situ RF exposure levels in the vicinity of an RBS installation after the product has been taken into operation; - describes several RF field strength and SAR measurement and computation methodologies with guidance on their applicability to address both the in-situ evaluation of installed RBS and laboratory-based evaluations; - describes how surveyors, with a sufficient level of expertise, establish their specific evaluation procedures appropriate for their evaluation purpose; - provides guidance on how to report, interpret and compare results from different evaluation methodologies and, where the evaluation purpose requires it, determine a justified decision against a limit value and - provides short descriptions of the informative example case studies given in the companion Technical Report IEC TR 62669] This second edition cancels and replaces the first edition published in 2011 and constitutes a technical revision.
