IEC 62232:2017 ED2

Determination of RF field strength, power density and SAR in the vicinity of radiocommunication base stations for the purpose of evaluating human exposure

Scope

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.
