This International Standard 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 standard: a) considers RBS which transmit on one or more antennas using one or more frequencies in the range 300 MHz to 6 GHz; b) 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; c) describes how surveyors with a sufficient level of expertise shall establish their specific evaluation procedures appropriate for their evaluation purpose; d) considers the evaluation purposes, namely: 1) product conformity: to establish that a RBS conforms to a defined set of limit conditions under its intended use; 2) compliance boundary: to establish the compliance boundary or boundaries for a RBS in relation to a defined set of limit conditions; 3) to evaluate RF field strength or SAR values at one or more evaluation locations, namely: i) evaluation location(s) at arbitrary locations outside the control boundary to provide information for interested parties; ii) evaluation location(s) at the control boundary to confirm validity of control boundary; iii) evaluation location(s) within the control boundary with the specific conditions relevant to investigate an alleged over-exposure incident; e) 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; f) provides informative guidance on how to evaluate ambient RF field strength levels in the vicinity of a RBS from RF sources other than the RBS under evaluation and at frequencies within and outside the range 300 MHz to 6 GHz; g) provides short descriptions of the informative example case studies to aid the surveyor given in the companion Technical Report IEC 62669.
