Meaning
South Korean technical standard establishing electromagnetic compatibility emissions requirements for multimedia equipment operating within the country. Compliance with the KN 32 EMC Standard is mandatory for commercializing computers, wireless gateways and network connected electronics in South Korea. Testing measures conducted emissions on power and telecommunications lines along with radiated emissions across specified radio frequency spectrums.
The regulation harmonizes Korean electromagnetic compatibility requirements with international CISPR 32 specifications.
Emission Limit
Accredited testing laboratories measure radiated fields inside semi-anechoic chambers to verify compliance with specified decibel limits. Demonstrating compliance with the KN 32 EMC Standard requires filtering power supplies and shielding internal printed circuit boards. Exceeding peak limit lines forces engineering modifications before approval grants.
Spectrum Compliance
Laboratory setups evaluate noise generated by internal clocks, switching regulators and memory interfaces. Applying the KN 32 EMC Standard ensures electronic hardware does not disrupt television broadcasting, cellular networks or local radio communications. Conducted emission testing covers AC mains ports and signal lines.
Market Authorization
Testing documentation forms the technical foundation for KC mark registration submitted to the National Radio Research Agency. Certificates citing the KN 32 EMC Standard allow manufacturers to place the official compliance label on device enclosures. Import shipments undergo customs checks to verify valid KC registration certificates.
