Measurement procedure for the assessment of specific absorption rate of human exposure to radio frequency fields from hand-held and body-mounted wireless communication devices - Part 3: Vector measurement-based systems (Frequency range of 600 MHz to 6 GHz)

IEC 62209-3: 2019 specifies measurement protocols and test procedures for the reproducible measurement of peak spatial-average specific absorption rate (psSAR) induced inside a simplified model of a human head or body by radio-frequency (RF) transmitting devices, with a specified measurement uncertainty. Requirements are provided for psSAR assessment using vector measurement-based systems. Such systems determine the psSAR by three-dimensional (3D) field reconstruction within the volume of interest in accordance with the requirements herein for the measurement system, calibration, uncertainty assessment and validation methods. The protocols and procedures apply for the psSAR assessments covering a significant majority of people including children during use of wireless communication devices operated in close proximity to the head or body.
This document is applicable to wireless communication devices intended to be used at a position near the human head or body at distances up to and including 200 mm. This document may be employed to evaluate SAR compliance of different types of wireless communication devices used next to the ear, in front of the face, mounted on the body, combined with other RF-transmitting or non-transmitting devices or accessories (e.g. belt-clip), or embedded in garments. The overall applicable frequency range is from 600 MHz to 6 GHz.
The system validation procedures provided within this document cover frequencies from 600 MHz to 6 GHz.
With a vector measurement-based system this document can be employed to evaluate SAR compliance of different types of wireless communication devices.
The wireless communication device categories covered include but are not limited to mobile telephones, cordless microphones, auxiliary broadcast devices and radio transmitters in personal computers, desktop and laptop devices, multi-band, multi-antenna, and push-to-talk devices.
Key Words: Human Exposure, Hand-Held and Body Mounted Wireless Communication Devices.

Procédure de mesure pour l'évaluation du débit d'absorption spécifique de l'exposition humaine aux champs radiofréquence produits par les dispositifs de communications sans fil tenus à la main ou portes près du corps - Partie 3: Systèmes basés sur la mesure vectorielle (plage de fréquences comprise entre 600 MHz et 6 GHz)

IEC 62209-3: 2019 spécifie les protocoles et procédures d'essai pour le mesurage reproductible du DAS maximal moyenné dans l'espace (psSAR – peak spatial-average specific absorption rate) induit à l'intérieur d'un modèle simplifié de tête ou de corps humain par des dispositifs d'émission de radiofréquence (RF), avec une incertitude de mesure spécifiée. Des exigences sont fournies concernant l’évaluation du psSAR utilisant des systèmes basés sur la mesure vectorielle. Ces systèmes déterminent le psSAR par reconstruction de champ tridimensionnel (3D) à l'intérieur du volume à l'étude conformément aux exigences du présent document relatives au système de mesure, à l'étalonnage, à l'évaluation de l'incertitude et aux méthodes de validation. Les protocoles et procédures s'appliquent pour les évaluations du psSAR couvrant une grande majorité de personnes, y compris les enfants, lors de l'utilisation de dispositifs de communications à proximité de la tête ou du corps. Le présent document s'applique aux dispositifs de communications sans fil destinés à être utilisés proches de la tête ou du corps humain, à des distances allant jusqu'à 200 mm inclus. Le présent document peut être utilisé pour évaluer la conformité du DAS de différents types de dispositifs de communications sans fil utilisés proches de l'oreille, devant le visage, sur le corps, en combinaison avec d'autres dispositifs ou accessoires de transmission RF ou pas (une attache de ceinture, par exemple) ou intégrés aux vêtements. La plage de fréquences globale applicable est comprise entre 600 MHz et 6 GHz. Les procédures de validation du système indiquées dans le présent document couvrent les fréquences comprises entre 600 MHz et 6 GHz. Avec un système basé sur la mesure vectorielle, le présent document peut être utilisé pour évaluer la conformité du DAS de différents types de dispositifs de communications sans fil. Les catégories de dispositifs de communications sans fil incluent, entre autres, les téléphones mobiles, les micros sans fil, les dispositifs de diffusion auxiliaires et les émetteurs radio dans les ordinateurs personnels, les ordinateurs de bureau et les ordinateurs portables, ainsi que les dispositifs à plusieurs bandes, à plusieurs antennes et à boutons-poussoirs.
