On October 20, 2025, Innovation, Science and Economic Development Canada (ISED) issued guidance number 2025-DRS0007, clarifying its guidelines based on RSS-102. SAR. MEAS Section 5.1 on the Simplification of SAR Evaluation Tests.

For any device that has performed a 1g body SAR test at a distance of 5 mm or less, a 10g limb SAR test at a distance of 0 mm is optional if all of the following conditions are met:

• Operating frequency below 6 GHz;
• The body and limbs use the same power level and power configuration set (Tune-up).

To apply this test simplification, you should describe how all of the above requirements are met in your report.

It is important to note that the limb SAR test simplification does not apply to:

• Exposure of the hand during voice calls near the head, as described in RSS-102. SAR.MEAS Section 5.10;
• Frequency above 6 GHz and for use at absorbed power density (APD) limits.
