IEC/IEEE 62209-1528:2020 specifies protocols and test procedures for the reproducible and repeatable measurement of the conservative exposure peak spatial average SAR (psSAR) induced inside a simplified model of the head and the body by radio-frequency (RF) transmitting devices, with a defined measurement uncertainty. These protocols and procedures apply to a significant majority of the population, including children, during the use of hand-held and body-worn wireless communication devices. These devices include single or multiple transmitters or antennas, and are operated with their radiating structure(s) at distances up to 200 mm from a human head or body. This document is employed to evaluate SAR compliance of different types of wireless communication devices used next to the ear, in front of the face, mounted on the body, operating in conjunction with other RF-transmitting, non-transmitting devices or accessories (e.g. belt-clips), or embedded in garments. The applicable frequency range is from 4 MHz to 10 GHz. Devices operating in the applicable frequency range can be tested using the phantoms and other requirements defined in this document. The device categories covered include, but are not limited to, mobile telephones, cordless microphones, and radio transmitters in personal, desktop and laptop computers, for multi band operations using single or multiple antennas, including push-to-talk devices. This document can also be applied for wireless power transfer devices operating above 4 MHz. This document does not apply to implanted medical devices. This first edition of IEC/IEEE 62209-1528 cancels and replaces IEC 62209-1:2016, IEC 62209-2:2010, IEC 62209 2:2010/AMD1:2019 and IEEE Std 1528:2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) extension of the frequency range down to 4 MHz and up to 10 GHz; b) testing of devices with proximity sensors; c) application specific phantoms; d) device holder specifications; e) fast SAR testing procedures; f) test reduction procedures; g) LTE assessment procedure; h) revision of validation clause, including validation antennas; i) revision of SAR assessment procedure; j) time-average SAR measurement procedure; k) uncertainty analysis; This publication is published as an IEC/IEEE Dual Logo standard.
