On December 5, 2025, the National Radio Research Agency (RRA) of Korea issued Notice No. 2025-9 to revise the Specific Absorption Rate (SAR) Measurement Standard. The announcement will be officially implemented on April 1, 2026, and existing equipment that complies with the old standard can continue to be considered compliant.

The revised standard takes the national standard KS C 3350 as the core, replacing the original KS C 3370-1 and KS C 3370-2 for the head and body/limbs, respectively, and unifies the SAR measurement method into a comprehensive measurement procedure based on IEC/IEEE 62209-1528:2020. At the same time, it is clear that this standard is applicable to SAR measurement stipulated in Article 4 of the "Electromagnetic Wave Human Protection Standard", and the names and provisions of the quoted standardization organizations are re-aligned.
