2. Factory inspection - Production equipment and processes are inspected and audited for compliance with applicable safety criteria.
3. Product testing - The product is tested consistent with the requirements of the applicable safety standard(s).
4. EMC testing - The product is tested for electromagnetic compatibility (EMC) and immunity.
5. Post-certification surveillance - Regular factory inspections and market surveillance are required to verify continued compliance following certification.

KC certification is ultimately issued by Korea-based certification bodies that have been approved by the Korea Standards Association (KSA).
