Ensuring safety from Radio Frequency (RF) exposure for wireless devices has become a regulatory requirement for many manufacturers around the globe. Measured in terms of the Specific Absorption Rate (SAR), tests are conducted on devices used closer than 20 cm to the head or body. Devices determined to be “safe” have SAR levels at or below the limits decided upon by the FCC, Industry Canada, European Union or other regulatory bodies internationally.
In answer to growing requests for SAR Testing, NWEMC opened the doors to our SAR Testing lab in January of 2011 at Our Hillsboro, Oregon location. Our SAR chamber is 12 ft. wide by 16 ft. long x 8 ft. high with a dedicated HVAC unit that provides +/- 1 degree C temperature control. To ensure reliable measurement results we selected the DASY5 from government-preferred vendor, SPEG of Zurich, Switzerland. The DASY5 is equipped with all necessary equipment needed for testing, including probes and phantoms.
Initially required mostly for cellular phone devices, SAR testing today is often required for a variety of devices, including system integrators and medical devices with radios that are operated closer than 20 cm to the head or torso. As technology has improved and smaller, more lightweight devices are becoming available, devices requiring testing can also include devices small enough to fit into a coat pocket or belt clip.
