Canada: ISED released RSS-102.SAR.MEAS Issue 2 and RSS-102.SAR.SIM Issue 1


On August 15, 2025, Innovation, Science and Economic Development Canada (ISED) released two new standards, RSS-102.SAR.MEAS Issue 2 and RSS-102.SAR.SIM Issue 1. The standards will take effect from the date of promulgation, and the transition period for the two standards will still be 6 months according to the usual practice.

The main updates to RSS-102. SAR. MEAS Issue 2 are as follows:

  • New requirements and instructions for Time Averaging (TAS) SARs for algorithm approval and final product implementation, including wireless wide area network (WWAN), wireless local area network (WLAN), non-terrestrial network (NTN), and Bluetooth (BT);
  • Added the Time Average Absorption Power Density (TA-APD) requirement for WLAN devices operating at 5925-7125 MHz.
  • TAS measurement requirements have been added, allowing TAS measurements to be performed using an array of Stage 2 fast SAR systems in accordance with IEC/IEEE 62209-1528;
  • clarified the test procedures for foldable devices;
  • Added requirements for TAS foldable devices and space separation antennas;
  • Added requirements for a variety of TAS applications;
  • TAS motion sensor guide has been added;
  • Added a new method for testing devices with protrusions.

The main updates to RSS-102. SAR. SIM Issue 1 are as follows:

  • The SAR measurement requirements refer to RSS-102.SAR.MEAS Issue 2;
  • The measurement requirements for Nerve Stimulation (NS) refer to RSS-102.NS.MEAS Issue 1;
  • NS The relevant simulation requirements refer to RSS-102.NS.SIM Issue 1;
  • The frequency range is extended from 100 kHz to 6 GHz, and the dielectric characteristics are adjusted accordingly;
  • introduced the SAM mannequin;
  • The requirements for uncertainty calculation are clarified.
