scope:

This document 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:

a) considers intentionally radiating RBS which transmit on one or more antennas using one or more frequencies in the range 110 MHz to 100 GHz;

b) considers the impact of ambient sources on RF exposure at least in the 100 kHz to 300 GHz frequency range;

c) specifies the methods to be used for RF exposure evaluation for compliance assessment applications, namely:

1) product compliance - determination of compliance boundary information for an RBS product before it is placed on the market;

2) 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;

3) 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;

d) 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;

e) describes how surveyors, with a sufficient level of expertise, establish their specific evaluation procedures appropriate for their evaluation purpose;

f) 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;

g) provides short descriptions of the informative example case studies given in the companion Technical Report IEC TR 62669 [1].
