New EMC Testing Standards Now in Effect in South Korea

-

On July 11, 2025, South Korea’s National Radio Research Agency (RRA) revised the country’s electromagnetic compatibility (EMC) testing methods to incorporate updates to national standards (KS) and correct minor typographical errors and inaccuracies. The revision improves alignment with international standards and provides greater clarity in regulatory application.


The updated methods adopt newly revised KS standards for various categories of wireless and electrical equipment. Key examples include:

  • KS X 3124:2024: Common technical requirements
  • KS X 3126:2024: Specific conditions for Broadband Data Transmission Systems
  • KS X 3128:2024: Specific conditions for Digital Enhanced Cordless Telecommunications (DECT) equipment
  • KS B ISO 8102-1:2020: Electrical requirements for lifts, escalators and moving walks — Part 1: Electromagnetic compatibility with regard to emission
  • KS C IEC 60947-1:2014 / KS C IEC 60947-2:2019 / KS C IEC 60947-4-1:2018: Low-voltage switchgear and controlgear


The revision also corrects publication year errors and clarifies the regulatory basis for certain test items to ensure consistent implementation, with the revised EMC testing methods taking effect one month after their official issuance.
