BS IEC/IEEE 62704-2:2017 establishes the concepts, techniques, validation procedures, uncertainties and limitations of the finite difference time domain technique (FDTD) when used for determining the peak spatial-average and whole-body average specific absorption rate (SAR) in a standardized human anatomical model exposed to the electromagnetic field emitted by vehicle mounted antennas in the frequency range from 30 MHz to 1 GHz, which covers typical high power mobile radio products and applications. This document specifies and provides the test vehicle, human body models and the general benchmark data for those models. It defines antenna locations, operating configurations, exposure conditions, and positions that are typical of persons exposed to the fields generated by vehicle mounted antennas. The extended frequency range up to 6 GHz will be considered in future revisions of this document. This document does not recommend specific peak spatial-average and wholebody average SAR limits since these are found in other documents, e.g. IEEE C95.1-2005, ICNIRP (1998).Cross References:IEC/IEEE 62704-1 Ed.1.0IEC 60050 (all parts)IEEE Std. 291-1991IEEE Std. 1309-2005IEEE Std.
