Executing Class Two Permissive Changes for Substituted Host Antennas
Substituted host antennas qualify for Class II Permissive Changes only when peak gain stays below certified limits and radiative physical structure remains identical.
KC Mark Update
Meaning
An administrative revision to South Korean conformity assessment requirements alters the compliance criteria for imported and domestic wireless and electronic products. Manufacturers must track every kc mark update to ensure their wireless modules and smart devices remain eligible for the Korean market. This process dictates whether existing certificates remain valid or if hardware modifications trigger a mandatory renewal of the certificate.
Regulatory Transition
National safety and electromagnetic compatibility standards undergo periodic revisions to address new radio frequencies and power limits. When a kc mark update takes effect, a transition period allows products already in the supply chain to be cleared, while new shipments must align with the revised test methods. This phase demands close coordination between the engineering team and local agents to avoid customs delays.
Device Compliance
Hardware changes during a product lifecycle often interact with updated regulatory guidelines. When a kc mark update introduces stricter spurious emission limits, a wireless module that previously passed may require redesign or shielding adjustment. Engineers must evaluate the module ratings against these updated limits by measuring the radiated power at the harmonic frequencies before submitting the file to the testing body.
This evaluation relies on a systematic comparison of the old test report against the new limits, focusing on the 2.4 GHz and 5 GHz bands to identify gaps. Consequently, the buyer must re-qualify the complete assembly rather than relying on the supplier’s original modular approval.
Approval Verification
Certifying agencies issue updated certificates once conformity is proven under the new rules. This document handover signals that the assembled product meets the current national standards, allowing the placement of the compliance label on the enclosure. Failure to secure the updated registration can result in the revocation of the import licence for the entire product line.
