IEEE P62704-4/D2, Aug 2019

P62704-4/D2, Aug 2019 is a technical standard for average specific absorption rate (SAR) assessment in the human body from wireless communications devices operating from 30 MHz to 6 GHz. It focuses on the general requirements for using the finite element method (FEM) for SAR calculations, making it relevant to electromagnetic analysis and device safety evaluation across fields, waves and electromagnetics, and communication technologies. This document is useful where consistent simulation methods are needed for design review and compliance-oriented studies.

P62704-4/D2, Aug 2019 overview

This standard addresses the FEM-based calculation framework used to estimate average SAR in human-body exposure scenarios for wireless devices. P62704-4/D2, Aug 2019 is aimed at providing general requirements that support repeatable modeling, analysis, and comparison of results within the 30 MHz to 6 GHz range. In practice, it helps define how electromagnetic simulations should be set up and interpreted when evaluating energy absorption, especially for product development, verification, and technical documentation.

Typical use cases

This document is typically used when engineers need a structured approach to SAR modeling for handsets, wearables, connected accessories, or other wireless communications devices. It is also relevant in simulation workflows that combine antenna behavior, human-body interaction, and electromagnetic field analysis. Organizations working on device design, RF engineering, and safety assessment may use P62704-4/D2, Aug 2019 to support consistent FEM studies, internal reviews, and comparison of SAR results across test conditions or design variants.

Why this standard matters
