About This Item
IEEE P1528a/D2.1 addresses how average specific absorption rate (SAR) is evaluated in the human head for wireless communications devices, with an amendment that includes a CAD file for the human head model, known as the SAM phantom. In the context of fields, waves and electromagnetics, this technical document supports more consistent exposure assessment and test setup. It is an inactive standard, but it remains relevant for understanding the development of SAR measurement methods.
IEEE P1528a/D2.1 overview
This amendment to the IEEE 1528-2003 framework focuses on the human head model used in SAR testing, adding a CAD file to better define the SAM phantom geometry. IEEE P1528a/D2.1 is relevant where wireless device evaluation depends on reproducible electromagnetic exposure measurements and controlled head-model positioning. By refining the test model, the document helps align analysis, laboratory practice, and compliance-related documentation for SAR assessment in head-relevant scenarios.
Typical use cases
IEEE P1528a/D2.1 is typically used when engineers or test labs need a defined head phantom model for SAR measurement of handheld or portable wireless communications devices. It may support simulation setup, validation of laboratory fixtures, and comparison of measurement results across test environments. The CAD file reference is especially useful in workflows that depend on accurate model geometry for repeatable electromagnetic evaluation, device development, and controlled safety testing.
Why this standard matters
This standard matters because SAR testing is closely tied to user safety, measurement consistency, and credible product evaluation. IEEE P1528a/D2.1 helps reduce ambiguity around the head model used in exposure assessments, which can improve repeatability and make results easier to compare. For organizations working with wireless device compliance or design verification, a clear phantom definition supports better risk control, more reliable testing, and more defensible technical records.
