1 Scope
This document specifies a conversion method for the assessment of the peak spatial-average absorbed power density ( psAPD ) in the human head and body due to exposure to radio frequency (RF) electromagnetic
fields (EMF) from wireless communication devices, with a specified conversion uncertainty.
This conversion method is based on specific absorption rate ( SAR ) values and is specified with the objective to yield conservative and reproducible
absorbed power density values of the exposure for a significant majority of the population during the use
of hand-held, body-worn or any other RF transmitting communication devices that can
operate in close proximity to a human head or body. This conversion method applies
for devices that can feature single or multiple transmitters and/or antennas and can
be operated with their radiating structure(s) at distances up to 200 mm from a human
head or body.
The conversion method of this document can be employed to determine conformity with
applicable absorbed power density or epithelial power density limits, such as those defined in ICNIRP guidelines 2020
[3] and IEEE Std C95.1™-2019 [4], of different types of RF transmitting communication devices being used in close
proximity to the head and body. The assessment of psAPD is based on the conversion of the peak spatial-average specific absorption rate ( psSAR ) values assessed according to applicable international standards. The applicable
frequency range of the conversion method of this document is 6 GHz to 10 GHz.
