Evaluating Permissive Change Compliance Paths for Potted RF Transmitter Modules
Adding potting compound to an unpotted RF module demands Class II permissive change re-testing if dielectric loading increases radiated spurious emissions.
KC Approval
Meaning
Conformity assessments are required by the South Korean government to verify that electronic and telecommunications equipment complies with national safety, electromagnetic compatibility, and radio frequency standards. Obtaining KC approval is necessary before any wireless device can be legally distributed or sold within South Korea. This requirement does not apply to prototypes or test samples imported for laboratory evaluation and research purposes.
Conformity Testing
Evaluation of the product must be conducted by a laboratory accredited by the National Radio Research Agency. During the process of securing KC approval, the hardware undergoes rigorous testing for electrostatic discharge resistance, radiated emissions and RF co-existence. The resulting test report is submitted to the government agency to obtain the unique conformity identifier.
This structured process guarantees that all imported or locally produced electronics meet South Korea’s strict safety standards.
Marking Requirement
Labeling rules require the official conformity mark and registration number to be clearly displayed on the product’s exterior. This label provides customs officials with verifiable proof of compliance during importation.
Market Entry
Distribution of electronic products without the required certification can result in severe financial penalties and confiscation of stock. This enforcement protects the domestic market from unsafe wireless devices.
