Korea KC Certification | GCA

On December 5, 2025, the National Radio Research Agency (RRA) issued a notification of a partial revision to the SAR measurement standards. The current SAR measuring procedures, KS C 3370-1 and KS C 3370-2, will be integrated into a new standard, KS C 3350, which closely aligns with IEC/IEEE 62209-1528:2020. This new SAR standard will take effect on April 1, 2026. Revisions to SAR Measuring Procedures Previous Standard: KS C 3370-1 (based on IEC 62209-1) and KS C 3370-2 (based on IEC 62209-2) Revised Standard: KS C 3350 The integration into KS C 3350 is expected to reduce inconsistencies that previously arose from using the two separate standards.
