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

This draft standard defines methodology 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, and procedures to validate correct implementation of FDTD simulation software. It does not recommend SAR limits, noting limits are provided in other guidelines (e.g., ICNIRP, IEEE C95.1).

Outcomes measured

peak spatial-average specific absorption rate (SAR) determination
FDTD methodology and validation procedures
uncertainty assessment for SAR simulations

Limitations

This is a draft standard/methodology document rather than an empirical health-effects study.
No SAR limit recommendations are provided in the document (limits referenced as external).
