Supplementary Procedure SPR-004 (Time-Averaged Specific Absorption Rate (TAS) Assessment Procedures for Wireless Devices Operating in the 4 MHz – 6 GHz Frequency Band) sets out the general test methods to be followed when carrying out an RF exposure compliance assessment of wireless devices implementing device-based time averaging methods for the management and/or mitigation of Specific Absorption Rate (SAR) in the 4 MHz – 6 GHz frequency band. Only ISED -approved TAS algorithms, listed below, can be implemented into wireless devices, including RF modules, for the purpose of equipment certification. This list will be updated on an ongoing basis, as new TAS algorithms are approved by ISED.

TAS algorithm approval is a lengthy process which takes several weeks and in some cases months, especially, when a physical evaluation is warranted. Applicants and other responsible parties (e.g. manufacturers, product integrators, recognized test laboratories/certification bodies) should consult Notice 2020-DRS0007 and contact ISED as early as possible.
