Conformity Registration Transfer Mechanisms for Korean Radio Equipment Importation
Transferring Korean KC radio registrations requires joint RRA filings, laboratory test report consent, and precise UNI-PASS importer matching to prevent border holds.
Class a Modification
Meaning
Substantial revision category for certified radio equipment describes changes that impact the core electrical performance or electromagnetic emissions of a device. A class a modification typically involves a redesign of the printed circuit board or a change to the radio frequency chipset. Such revisions require a complete re-evaluation of the original test data to ensure continued compliance.
The designation forces a new application to the certification body because the previous results no longer represent the current hardware state.
Technical Impact
Changes to the trace layout or the addition of new frequency bands fall under this classification. The technical impact of class a modification necessitates a full suite of radiated and conducted emission tests. Hardware engineers must provide updated schematics and a detailed description of the circuit changes.
This level of change assumes the risk of interfering with other devices is substantially altered.
Testing Requirement
Validation of the new design occurs at an accredited laboratory through a repeat of the initial certification program. The testing requirement of class a modification involves checking the peak power and harmonic suppression of the transmitter. Engineers must submit the modified samples for physical inspection.
This rigorous path prevents unverified hardware from reaching the consumer.
Approval Status
Issuance of a revised certificate marks the end of the regulatory cycle for these major changes. The approval status of class a modification is recorded in the national database to maintain traceability. New production runs must carry the updated identification number.
