IEC 62232:2017(E)提供了确定无线电通信基站(RB)附近射频(RF)场强和比吸收率(SAR)的方法，以评估人体暴露。本文件:-考虑有意地辐射使用110MHz至100GHz范围内的一个或多个频率在一个或多个天线上发射的RB；-考虑至少在100kHz至300GHz频率范围内环境源对RF暴露的影响；-规定了用于符合性评估应用的射频暴露评估的方法，即:？-产品合规性-在RBS产品投放市场之前确定其合规性边界信息；？-产品安装合规性-在产品投入使用之前，确定RBS产品和其他相关来源在可触及区域的总射频暴露水平；？-现场射频暴露评估-在产品投入运行后测量RBS设施附近的现场射频暴露水平；-描述了几种射频场强和合成孔径雷达测量和计算方法，并指导其适用性，以解决已安装的射频场强和合成孔径雷达的现场评估和基于实验室的评估；-描述具有足够专业知识的测量员如何建立适合其评估目的的特定评估程序；-就如何报告、解释和比较不同评估方法的结果提供指导，并在评估目的需要时，根据限值确定合理的决定，以及-提供配套技术报告IEC TR 62669[1]中给出的信息丰富的示例案例研究的简短描述第二版取消并取代了2011年出版的第一版，构成技术修订。

IEC 62232:2017(E) 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 [1]
This second edition cancels and replaces the first edition published in 2011 and constitutes a technical revision.
