(Amendment)Amendment 1 - Determination of RF field strength, power density and SAR in the vicinity of base stations for the purpose of evaluating human exposure
Amendment 1 - Determination of RF field strength, power density and SAR in the vicinity of base stations for the purpose of evaluating human exposure
IEC 62232:2025 provides methods for the determination of RF field strength, power density and specific absorption rate (SAR) in the vicinity of base stations (BS) for the purpose of evaluating human exposure.
This document:
a) considers intentionally radiating BS which transmit on one or more antennas using one or more frequencies in the range 110 MHz to 300 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 a BS product before it is placed on the market;
2) product installation compliance – determination of the total RF exposure levels in accessible areas from a BS product and other relevant sources before the product is put into operation;
3) in-situ RF exposure assessment – measurement of in-situ RF exposure levels in the vicinity of a BS installation after the product has been taken into operation;
d) specifies how to perform RF exposure assessment based on the actual maximum approach;
e) describes several RF field strength, power density, and SAR measurement and computation methodologies with guidance on their applicability to address both the in-situ evaluation of installed BS and laboratory-based evaluations;
f) describes how surveyors establish their specific evaluation procedures appropriate for their evaluation purpose;
g) 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;
h) provides methods for the RF exposure assessment of BS using time-varying beam-steering technologies such as new radio (NR) BS using massive multiple input multiple output (MIMO).
NOTE 1 Practical implementation case studies are provided as examples in the companion Technical Report IEC TR 62669 [5].
NOTE 2 Although the current BS product types have been specified to operate up to 200 GHz (see, for example, [6] and [7]), the upper frequency of 300 GHz is consistent with applicable exposure limits.
NOTE 3 The lower frequency considered for ambient sources, 100 kHz, is derived from ICNIRP-1998 [2] and ICNIRP-2020 [1]. However, some applicable exposure guidelines require ambient fields to be evaluated as low as 3 kHz, e.g. Safety Code 6 [4] and IEEE Std C95.1-2019 [3].
NOTE 4 Specification of appropriate RF exposure mitigation measures such as signage, access control, and training are beyond the scope of this document. It is possible to refer to the applicable regulations or recommended practices on these topics.
NOTE 5 While this document is based on the current international consensus about the best engineering practice for assessing the compliance of RF exposure with the applicable exposure limits, it is possible that national regulatory agencies specify different requirements. The entity conducting an RF exposure assessment needs to be aware of the applicable regulations.
This fourth edition cancels and replaces the third edition published in 2022. It includes corrections of obvious errors and text improvements on the third edition in order to bring more clarity in the description of the assessment methods and avoid misinterpretations. This edition has the same technical content as the third edition.
Bestimmung der HF-Feldstärke, der Leistungsdichte und der spezifischen Absorptionsrate (SAR) in der Nachbarschaft von Funkkommunikations-Basisstationen zur Ermittlung der menschlichen Exposition
Détermination de l'intensité du champ de radiofréquences, de la densité de puissance et du das à proximité des stations de base dans le but d'évaluer l'exposition humaine
IEC 62232:2025 donne des méthodes de détermination de l'intensité de champ RF, de la densité de puissance et du débit d'absorption spécifique (DAS) à proximité des stations de base (BS) dans le but d'évaluer l'exposition humaine.
Le présent document:
a) examine des BS rayonnant intentionnellement qui émettent sur une ou plusieurs antennes dans la plage de fréquences de 110 MHz à 300 GHz;
b) étudie l'impact des sources ambiantes d'exposition RF au moins dans la plage de fréquences de 100 kHz à 300 GHz;
c) spécifie les méthodes d'évaluation de l'exposition RF à utiliser pour les applications d'appréciation de la conformité, à savoir:
1) conformité du produit: détermination des informations sur la frontière de conformité d'un produit BS avant sa commercialisation;
2) conformité de l'installation du produit: détermination des niveaux d'exposition RF totaux dans les zones accessibles depuis un produit BS et les autres sources pertinentes avant la mise en service du produit;
3) appréciation de l'exposition RF sur site: mesurage des niveaux d'exposition RF sur site à proximité d'une installation BS après la mise en service du produit;
d) spécifie la manière de procéder à l'appréciation de l'exposition RF en s'appuyant sur l'approche fondée sur la réelle maximale;
e) décrit plusieurs méthodologies de mesure et de calcul de l'intensité de champ RF, de la densité de puissance et du DAS avec des recommandations relatives à leur applicabilité pour couvrir tant l'évaluation sur site des BS installées que les évaluations en laboratoire;
f) décrit la manière dont les vérificateurs établissent leurs propres procédures d'évaluation, en fonction de leurs objectifs d'évaluation;
g) fournit des recommandations quant à la manière de rendre compte, d'interpréter et de comparer les résultats obtenus à partir de différentes méthodologies d'évaluation et, lorsque l'objectif de l'évaluation l'exige, prendre une décision justifiée en vertu d'une valeur limite donnée;
h) fournit les méthodes d'appréciation de l'exposition RF de la BS à l'aide de technologies à orientation de faisceau variable dans le temps telles que les BS New Radio (NR) qui utilisent la technologie de système massif à entrée multiple et sortie multiple (MIMO, Multiple Input Multiple Output).
NOTE 1 Des exemples d'études de cas de mise en œuvre pratique sont donnés dans le Rapport technique d'accompagnement IEC TR 62669 [5].
NOTE 2 Bien que les produits BS actuels soient conçus pour fonctionner jusqu'à 200 GHz (voir par exemple [6] et [7]), la fréquence supérieure de 300 GHz est cohérente avec les limites d'exposition applicables.
NOTE 3 La fréquence inférieure prise en considération pour les sources ambiantes, 100 kHz, provient de l'ICNIRP 1998 [2] et de l'ICNIRP-2020 [1]. Toutefois, certaines lignes directrices applicables en matière d'exposition exigent d'évaluer les champs ambiants à des valeurs aussi basses que 3 kHz (Code de sécurité 6 [4] et IEEE Std C95.1-2019 [3], par exemple).
NOTE 4 La spécification de mesures appropriées d'atténuation de l'exposition RF, telles que la signalisation, le contrôle d'accès et la formation, ne relève pas du domaine d'application du présent document. Il est possible de consulter les règlements applicables ou les pratiques recommandées sur ces sujets.
