scope:

The scope of this standard is to define the methodology for the application of the finite difference time domain (FDTD) technique when used for determining the peak spatial-average specific absorption rate (SAR) in the human body exposed to wireless communication devices with known uncertainty. It defines methods to validate the numerical model of the device under test (DUT) and to assess its uncertainty when used in SAR simulations. Moreover, it defines procedures to determine the peak spatial-average SAR in a cubical volume and to validate the correct implementation of the FDTD simulation software. NOTE Cubical averaging volumes are applied in all current experimental standards for the assessment of psSAR and recommended by [B46], [B47] and [B55]. Other averaging volumes have been proposed, e.g., in [B46], and may be included in future revisions of this standard. This document does not recommend specific SAR limits since these are found elsewhere, e.g., in the guidelines published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) [B46] or in IEEE C95.1 [B55].
