According to the EN 62232: 2017 one of the methods of ensuring compliance in the vicinity of radiocommunication base station (RBS) is to perform SAR testing of the base station antennas for the purpose of evaluating human exposure. This can be undertaken by EMC Technologies in Melbourne, Australia with their DASY 52 SAR measurement system. SAR method is recommended if the exposure occurs in the region of the reactive near-field of the source (antenna). SAR testing is the most advanced and accurate way of obtaining whole-body RF exposure for the purpose of determining the exclusion zone around the radiating structures. This is applicable to both occupational (aware persons with some knowledge of RF hazards) and the general public (unaware persons with no knowledge of RF hazards, or pregnant) SAR limits.

The SAR measurement’s procedures are generally applicable to small standalone devices shorter than 1.5m and tested at the distance not greater than 1m, in practice at a distance of approximately 0.5 meters.

Multiple methods could be applied sequentially or simultaneously to evaluate exposure close to RBS antennas, however the SAR measurement is the highest-ranking and most trusted method and is always applicable at very close proximity to the radiating structure.

EMC Technologies can on short notice accommodate SAR testing of antennas not larger than 60 x 40 cm ellipse (Eli4 test Phantom) to evaluate Peak Spatial Average SAR or larger antennas up to 1.54 x 0.339 m box-shaped for Whole-Body SAR if given some time to assemble the test system.
