CanadaTime-Averaged Specific Absorption Rate (TAS) Protocol
The ISED in Canada as of April 20th, 2020 specified the certification requirements for the use of time-averaged specific absorption rate protocols to show compliance of radio devices with the RF Exposure requirements as defined in the applicable Canadian standard RSS-102. The Notice 2020 – DRS0007 allows the use of dynamic power level management to control the specific absorption rate of devices (SAR) over a specific time period and defines the specific requirements to be met before such an approach may be used. Those restrictions include but are not limited to a consultation with the ISED prior to seeking certification, a pre-approval of the time averaging protocol used and the time-averaging period and methodology.
The issuance of the notice was necessary because of the lack of standardized test methods and protocols to cover this new evolvement in the development of transmitting devices.
Please note that the necessary testing must be performed at a ISED recognized testing laboratory.
