Abstract

IEC/IEEE Draft Standard for Determining the SAR from Wireless Devices, 30 MHz to 6 GHz. Part 1: General Requirements for using the Finite Difference Time Domain (FDTD) Method International Electrotechnical Commission (IEC), Institute of Electrical and Electronics Engineers (IEEE). IEC/IEEE Draft Standard for Determining the Peak Spatial Average Specific Absorption Rate (SAR) in the Human Body from Wireless Communications Devices, 30 MHz to 6 GHz. Part 1: General Requirements for using the Finite Difference Time Domain (FDTD) Method for SAR Calculations. 2022, IEEE/IEC P62704-1: 1-82. Abstract This standard defines the methodology for the application of the finite difference time domain (FDTD) technique when used for determining the peak spatial-average specific absorption rate (SAR) in the human body exposed to wireless communication devices with known uncertainty. It defines methods to validate the numerical model of the device under test (DUT) and to assess its uncertainty when used in SAR simulations. Moreover, it defines procedures to determine the peak spatial average SAR in a cubical volume and to validate the correct implementation of the FDTD simulation software. This document does not recommend specific SAR limits since these are found elsewhere, e.g., in the guidelines published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) or in IEEE C95.1 standards.ieee.org

Main findings

The draft standard defines methodology and general requirements for applying the finite difference time domain (FDTD) technique to determine peak spatial-average SAR in the human body from wireless communication devices, including model validation and uncertainty assessment procedures. It also specifies procedures for determining peak spatial average SAR in a cubical volume and validating correct implementation of FDTD simulation software; it does not recommend SAR limits.

Outcomes measured

Peak spatial-average specific absorption rate (SAR) determination methodology
FDTD method requirements for SAR calculations
Validation of numerical device model (DUT)
Assessment of uncertainty in SAR simulations
Procedures for peak spatial average SAR in a cubical volume
Validation of FDTD simulation software implementation

Limitations

This is a draft standard/methodology document rather than a health-effects study.
No specific SAR limits are recommended; limits are referenced as being in other guidelines (e.g., ICNIRP, IEEE C95.1).
No empirical exposure/health outcome data are presented in the abstract.
