Smart Hardware Certification (Smart Watches / Bands / Rings) CCC · SRRC · Network Access

What This Line Covers

Typical smart hardware products and test scenarios — Smart Hardware: Structure, Antenna and Power Design Decide the Certification Path

Scope covers wearables (watches, bands, rings, health monitoring patches), audio (TWS, over-ear, open-fit and bone-conduction earphones), smart glasses and AR glasses, consumer drones and aerial imaging devices, service and educational robots, action cameras, translation pens and recording devices, power banks and wireless charging devices. Technically, BLE 5.x/6.0, Wi-Fi 2.4G/5G/6GHz, NFC, UWB, GNSS and cellular (Cat.1, Cat.4, 5G, eSIM) combinations coexist; most products pair with a phone app, and RF coexistence and human exposure assessment are shared difficulties.

What we do: device-level and module-level pre-testing, antenna matching and RF power rectification, SAR over-limit rectification, shielding and filtering design, CCC/SRRC/CTA filing documents, and series model extension and difference statements.

First, the catalogCCC by product categorySimilar products in different forms may fall under different catalogs — household appliances, IT/AV, lighting — and a wrong determination is returned at formal review.

Then, transmissionSRRC looks at the finished deviceAny device containing an active transmitting module needs type approval; an approved module simplifies but does not replace device-level filing.

Finally, accessNetwork access applies to public networksOnly terminals and inter-network equipment connected to the public telecom network require it; purely local-area devices do not need it for every product.

Certification Matrix

Broken down by product form, so you can see at a glance which certificates and test items apply:

Sub-category	Typical products & technical features	Core compliance items	Special & value-added
Wearables	Smart watches, bands, rings; BLE + GNSS, worn against the body for long periods	SRRC type approval; CCC (including adapter and built-in lithium battery); SAR and human exposure assessment; GB 4943.1 safety	Cellular versions need a separate CTA; health data and personal information compliance assessment
Audio devices	TWS, over-ear and bone-conduction earphones; BLE + proprietary 2.4G	SRRC; GB 4943.1; EMC; lithium battery GB 31241 and UN38.3	Bluetooth SIG certification; call and noise-cancelling performance testing
Glasses & AR	Camera glasses, AR headsets; Wi-Fi 6 + BLE, with camera	SRRC; CCC (audio-visual); photobiological safety	Camera data compliance assessment; wearing comfort and battery life
Drones	Consumer aerial cameras; 2.4G/5.8G video link + GNSS	SRRC; GB 42590 safety requirements for civil unmanned aircraft systems; battery UN38.3	Low-power short-range device compliance assessment; real-name registration guidance
Power products	Power banks, wireless charging pads; fast-charge protocols	CCC (power banks and lithium-ion batteries are now in the compulsory catalog); GB 31241	Fast-charge protocol compatibility testing; temperature rise and cycle life

“Core compliance items” are what regulations or industry access require; “special & value-added” items are supplementary work that strengthens competitiveness in tenders, central procurement and channel access. The table shows common cases; in practice each item is verified against the product function list and the current catalog.

The Most Common Pitfalls on This Line

All of these have caused rework in real projects — avoiding them early saves 2–4 weeks:

Pitfall 01Charging cases and adapters missed for CCCThe earbuds got SRRC but the charging case and bundled adapter had no CCC, and the channel blocked the listing. From project kick-off, list “device + accessories” together.

Pitfall 02Power banks are now in the CCC compulsory catalogPower banks and lithium-ion batteries are compulsory under the catalog, and export-to-domestic-sales or old habits are where omissions happen. Check bundled lithium batteries against GB 31241 and UN38.3 at the same time.

Pitfall 03Antenna swapped without retestingSwapping a ceramic antenna for FPC, or FPC for LDS, changes the electrical length; the original approval data cannot simply be cited — retest the device or perform a change assessment.

Pitfall 04SAR and wearing scenariosTransmitting devices used close to the body need a SAR applicability assessment; the watch case-back material and antenna position directly affect the conclusion.

What Gets Tested — and What We Pre-test

Formal testing takes place at designated laboratories; before submission we run baseline checks in our own RF anechoic chamber and EMC lab, so fixable issues are solved in-house.

RF and spurious emission pre-testing — Pre-test: transmit power, frequency tolerance and spurious curves checked up front

RF metrics: frequency tolerance, transmit power, power spectral density, spurious
EMC: radiated disturbance, conducted disturbance, ESD and surge
SAR / human exposure applicability assessment
Battery and charging safety pre-assessment (GB 31241 / UN38.3)

Pre-testing is not a formality. In projects on this line, spurious emissions, harmonics and EMC account for most rework, and 3–5 days of baseline testing up front often saves a whole round of laboratory queuing.

Timeline and How We Measure It

Path assessment1–3 business days

We review the datasheet, antenna documents and network topology, then issue a written determination: which certificates are needed and whether units can be combined.

In-house pre-testing3–5 business days

Baseline runs in the anechoic chamber and EMC lab; over-limit items are fixed first, avoiding a queued formal test that gets returned.

Formal submission2–6 weeks

Samples go out per the designated laboratory's schedule; we track progress and rectify non-conforming items.

Filing & issuance2–4 weeks

Document submission, formal review, certificate issuance and marking instructions — each milestone is shared with the project owner.

Overall reference timeline 8–12 weeks, compressible with parallel filing; structural changes or retests extend it accordingly. Fees are quoted item by item according to certification scope and number of models; reference ranges are subject to our written assessment.

FAQ

A band comes in 9 colours and 3 strap types — do they need separate SRRC approvals?

Where RF and structure are identical and only the colour differs, they can generally be combined into one filing unit, with a lead model tested and the rest listed as covered models; if strap material or structure around the antenna changes RF behaviour, a separate assessment is needed. We mark each model “can combine / must test” in the assessment table.

TWS earbuds use an approved Bluetooth module — does the device still need SRRC?

Yes. Module approval covers the module itself; the device's antenna, housing and power supply all change radiation characteristics, so device approval is still required. Citing module data simplifies test items but does not replace device filing.

A watch with eSIM — when should the network access license be filed?

Cellular versions are managed as telecom terminals; the network access license and SRRC can prepare documents in parallel, but samples must be provided with the final commercial software version so later software changes do not break certificate consistency.
