SIMULATING LIQUID PARAMETERS CHECK
The simulating liquids should be checked at the beginning of a series of SAR measurements to determine
of the dielectric parameters are within the tolerances of the specified target values. The relative
permittivity and conductivity of the tissue material should be within
of the dielectric parameters are within the tolerances of the specified target values. The relative
permittivity and conductivity of the tissue material should be within
± 5% of the values given in the table
below.

Reference Values of Tissue Dielectric Parameters for Head and Body Phantom
(for 150 – 3000 MHz and 5800 MHz)
(for 150 – 3000 MHz and 5800 MHz)
The head tissue dielectric parameters recommended by the IEEE SCC-34/SC-2 in IEEE Standard 1528
have been incorporated in the following table. These head parameters are derived from planar layer
models simulating the highest expected SAR for the dielectric properties and tissue thickness variations
in a human head. Other head and body tissue parameters that have not been specified in P1528 are
derived from the tissue dielectric parameters computed from the 4-Cole-Cole equations and extrapolated
according to the head parameters specified in IEEE Standard 1528.
