Radio Frequency Testing

KCC compliance for Bluetooth headsets in Korea—RF/EMC testing, safety/battery checks, documentation, and submission support. CNAS/CMA/A2LA credentials as publicly disclosed. Contact Deng: 13925591357 / net04@gtggroup.com.

What we do

We offer end‑to‑end, verifiable support for Korean KCC certification. We do not replace official approval processes and do not make “fast pass” or fixed‑time promises.

• Compliance scoping and gap analysis: define applicable modules and a clear test/file checklist.
• Laboratory validation: RF (2.4 GHz Bluetooth), EMC; safety and battery evaluations if chargers or Li‑ion packs are included.
• Documentation and labeling review: marking, user manual, declarations, antenna data.
• Submission support and query handling: compile files, liaise, and track status; final decisions rest with the authorities.
• Capacity: 300+ staff, 30,000 m² lab, 2,000+ instruments, 24/7 service; PhD‑led GMA team covering 130+ countries/regions (data source: GTG internal statistics; subject to agreements and official reviews).

Scope and typical tests for Bluetooth headsets

• RF: output power, spectrum occupancy, spurious/out‑of‑band emissions, duty cycle.
• EMC: radiated/conducted emissions; immunity as applicable to the finished product and charging case.
• Human exposure (SAR/MPE) where required based on power, construction, and usage.
• Safety/charger: applicable IT/AV/power safety and charging protection if bundled accessories apply.
• Battery: Li‑ion cell/pack safety and charging controls (transport compliance managed separately).
• Labeling and user documents: KC/KCC marking, IDs, warnings, user instructions per Korean rules.
• Technical file: antenna and PCB data, key component list (BOM), specs, and consistency records.

Note: Items above are indicative. Exact scope depends on official requirements and product configuration.

Process and timeline factors

1. Requirement briefing: model definition, features, market timing.
2. Samples and files: BOM, antenna and RF parameters, label draft, user manual draft.
3. Testing: RF/EMC and, where applicable, exposure/safety/battery; issue a findings list.
4. Fixes and re‑tests: layout/shielding/filtering and design updates, then verification.
5. Dossier finalization and submission: report, labeling, and consistency checks; authority review.

Timeline drivers: applicable standards/modules, product complexity, completeness of samples/files, number of fix rounds, and authority queueing.

FAQs

Is “KCC” the same as KC？
Industry usage often says “Korean KCC certification” for radio/EMC compliance managed under the KC framework. Follow the latest official requirements for your product.

Do all Bluetooth headsets need SAR?
It depends on power, construction, and use conditions. The need and method are defined by the applicable rules and the product’s specifics.

Can CE/FCC reports be reused for Korea?
Generally not directly recognized. They help with pre‑assessment and risk identification, but in‑country compliance is still required.

If the Bluetooth module is certified, can the whole product skip testing?
Module compliance helps, but whole‑device testing depends on antenna placement, enclosure, layout, and coexistence factors as judged by the rules and authorities.
