This document details the standards and test items for South Korea's KCC Radio Certification, incorporating the latest 2025 dynamics.
| Test Category | Core Focus | Primary Standards/References |
| RF Performance | Frequency range, output power, frequency stability, modulation, occupied bandwidth, spurious emissions. | RRA Announced Standards (typically aligned with ETSI/ITU). |
| EMC | EMI emissions (conducted/radiated), immunity (ESD, EFT, etc.). | KS X 3124 (General), KS X 3126 (Broadband, incl. 5G), KN 301 489 (equiv. to EN 301 489). |
| SAR | RF energy absorption rate for body-worn devices (phones, earphones). | Korean limit is 2.0 W/kg (aligns with EU). |
| Electrical Safety | Electrical insulation, fire prevention, shock hazard. | KN 60950-1. Trend: Transitioning to KS X IEC 62368-1. |
Key Test Item Details：
1.RF Testing ("Legal Transmission"): Verifies radio parameters. Focus on frequency range & power staying within licensed Korean limits. Spurious emissions are critical to prevent interference.
2.EMC Testing ("Harmonious Coexistence"): Ensures device operates normally in noisy environments without disrupting others. Key 2025 Update: Major EMC standards (KS X 3124, 3126) were updated, aligning with ETSI and adding requirements for new tech (e.g., mmWave). Mandatory after Dec 1, 2025 transition.
3.SAR Testing (User Safety):Mandatory for body-worn devices. Ensures RF exposure remains within safe limits.
2025 Updates & Practical Guide：
1.EMC Standards Upgraded: Affects 5G, Wi-Fi 6E devices, potentially increasing test complexity/cost.
2.Safety Standard Transition: Safety standards are shifting from KN 60950-1 to IEC 62368-1. New designs should target the newer standard.
3.Ongoing System Optimization: RRA continues refining the system, e.g., introducing a Self-Compliance Verification system for low-risk products.
