On December 23, 2025, the Korean Agency for Technology and Standards (KATS) issued an announcement No. 2025-370 , proposing a revision to the safety standard KC 60335-2-29 (Household and Similar Electrical Appliances – Safety – Part 2-29: Particular Requirements for Battery Chargers). This revision aims to update the safety standards in alignment with international standards. KATS is collecting public opinions on the proposed amendment until February 3, 2026. Key Revisions Update of IEC Edition: Ed 5.0 (2016-06) → Ed 5.1 (2019-03) Expansion of ripple-free DC output range: Up to 120 V → Up to 250 V Classification of charger types based on transformer specifications: - Type 1: Battery charger output circuits supplied through a safety isolating transformer (DC output voltage must not exceed 120 V) - Type 2: Battery charger output circuits supplied through an isolating transformer (DC output voltage must not exceed 250 V) GCA Korea provides expert support for globa...

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.
