Subcommittee 1: Experimental Techniques

The purpose of this sub-committee is to develop protocols for the measurement of the peak spatial average SAR in simplified models of the head and body of users of radio transceivers used for wireless communications services. It applies to contemporary and future devices with the same operational characteristics as contemporary devices that operate in the 300 MHz–6 GHz frequency range and provides a conservative estimate of the peak spatial average SAR representative of that which would be expected to occur in a significant majority of persons during normal use of these devices, but which may not be the absolute maximum value that could possibly occur under every conceivable combination of size and shape of the body, device orientation, and spacing relative to the body.

Subcommittee 1 was established in February 1997. The scope of Subcommittee 1 covers a variety of devices. It initially focused on a recommended practice devoted exclusively to handsets used for personal wireless communication services. The first IEEE 1528 standard (IEEE Std 1528TM-2003) specifies protocols for the measurement of the peak spatial-average SAR in the head of users of certain hand-held radio transceivers that are used for personal wireless communications, operate in the 300 MHz – 3 GHz frequency range, and are intended to be operated while held against the ear. Specifically, this recommended practice describes the concepts, measurement techniques, instruments, calibration techniques, phantom models for SAR system validation, and limitations of systems used for measuring the radio frequency (RF) electric field strength for purposes of determining the spatial-peak mass-averaged SAR, e.g., per 1 gram or 10 grams of tissue, in simulated tissue models, including homogeneous anatomical models of the human head.

Protocol requirements of IEEE Std 1528TM-2003, which have been incorporated into IEC Std 62209-1, are the primary globally adopted or referenced standards to assess the SAR in near field exposures.


Subcommittee 2: Numerical Standards

The purpose of these standards is to specify numerical techniques and standardized anatomical models used for determining the spatial peak specific absorption rates (SAR) in the human body of users for wireless communication devices. SAR is determined by applying Finite Difference Time Domain (FDTD) or Finite element techniques to simulate the field conditions produced by wireless devices in anatomically correct models of the human anatomy. Intended users of this practice will be (but will not be limited to) wireless communication device manufacturers and wireless service providers that are required to certify that their products comply with the applicable SAR limits and government regulations.
