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.

General Information
Overview
SIST EN IEC 62209-3:2021 specifies measurement procedures for assessing the peak spatial‑average specific absorption rate (psSAR) of human exposure to radio‑frequency (RF) fields from hand-held and body‑mounted wireless communication devices. It covers vector measurement‑based systems that reconstruct three‑dimensional (3D) fields to determine psSAR in simplified head and body models. The standard applies to devices operating in the 600 MHz to 6 GHz frequency range and to use positions up to and including 200 mm from the head or body. Typical device categories include mobile phones, cordless microphones, body‑worn transmitters, embedded garment radios, and multi‑antenna or multi‑band devices.
Key topics and technical requirements
- psSAR assessment using vector measurement systems: Systems determine psSAR by 3D field reconstruction inside the volume of interest, with requirements for calibration, uncertainty estimation and validation.
- Measurement system specifications: Defines requirements for scanning systems and array measurement systems, dosimetric probe calibration, and device holders.
- Phantom and tissue‑equivalent media: SAM (Specific Anthropomorphic Mannequin) and flat phantom geometries and the properties of tissue‑equivalent liquids or materials are specified.
- Reconstruction algorithms: Requirements for field reconstruction and peak spatial‑averaging to compute psSAR from measured vector fields.
- System check and system validation: Procedures, test antennas, acceptance criteria and validation tests to confirm measurement reproducibility across 600 MHz–6 GHz.
- Measurement uncertainty: Models, uncertainty budgets and evaluation methods aligned with international guidance to ensure specified uncertainty of psSAR results.
- Reporting: Required content for measurement reports, including calibration, test setup, uncertainties and validation evidence.
Practical applications and users
Who uses this standard:
