This document provides information on SPEAG's head tissue simulating liquids, specifically the HBBL4-250V3 and HBBL600-10000V6 models. These liquids are designed for specific absorption rate (SAR) testing, ensuring compliance with industry standards such as IEEE 1528, IEC 62209-1/2, and FCC KDB 865664. The liquids are packaged in 10-liter containers with nozzles for easy dispensing.
The document includes detailed measurements of the dielectric parameters of the liquids, such as permittivity (e') and conductivity (sigma), at various frequencies. These measurements are compared to target values defined in the relevant standards, ensuring that the liquids accurately simulate the electrical properties of human head tissue. The document also provides information on the composition of the liquids, including the main ingredients used in their formulation.
SPEAG offers a range of tissue simulating liquids for different frequency ranges, and custom liquids can be provided upon request. The document also includes information on the lifetime and stability of the liquids, as well as recommendations for their storage and handling.
