About This Item
IEEE P62704-1/D2, Oct 2013 is an IEC/IEEE draft standard focused on determining the peak spatial average specific absorption rate (SAR) in the human body from wireless communications devices operating from 30 MHz to 6 GHz. It provides a technical basis for evaluating exposure from RF sources using the finite difference time domain (FDTD) method, which is important for consistent analysis in fields, waves, electromagnetics, and communication device engineering. IEEE P62704-1/D2, Oct 2013 supports safer design and more reliable SAR calculations.
IEEE P62704-1/D2, Oct 2013 overview
This draft standard defines general requirements for using the finite difference time domain method when calculating peak spatial average SAR in human-body models. It is aimed at electromagnetic simulation work where wireless devices must be assessed across the 30 MHz to 6 GHz range. The document helps align calculation practices so results are more comparable across testing and development workflows. As a draft technical specification, IEEE P62704-1/D2, Oct 2013 is relevant to engineers who need structured SAR evaluation methods.
Typical use cases
IEEE P62704-1/D2, Oct 2013 is commonly used in modeling and simulation workflows for handsets, wearables, portable transmitters, and other wireless communications devices. It is also relevant when reviewing product designs that interact with the human body and when preparing SAR studies for engineering or compliance purposes. The standard supports FDTD-based analysis in research, product development, and lab validation environments where peak spatial average SAR must be estimated with repeatable assumptions and defined calculation practices.
Why this standard matters
This standard matters because SAR assessment is closely tied to human exposure evaluation, product design control, and technical consistency. By setting general requirements for FDTD-based calculations, it helps reduce variation in simulation setup and interpretation. That can improve confidence in engineering decisions, support internal compliance reviews, and make procurement or verification comparisons more meaningful. For teams working with RF device design, IEEE P62704-1/D2, Oct 2013 offers a clearer framework for documenting and checking SAR results.
