Certifying a Bluetooth Low Energy Wearable
Guide, Bluetooth LE wearable
A band, a watch or a connected ring that speaks Bluetooth Low Energy looks simple, yet placing it on the market mobilises half a dozen distinct compliance regimes. The radio must be certified in every region (EU, US, Canada at minimum), the Bluetooth brand requires a consortium qualification, body-worn radio exposure must be justified, the lithium battery follows its own safety and transport tests, the firmware now falls under European cyber law, and substances and waste fall under environmental law. This page is a route map: it links each strand to its detailed guide and provides a decision table for when a wearable tips from a wellness product into a medical device.
Overview: seven compliance strands
Section titled “Overview: seven compliance strands”A BLE wearable is not covered by a single certification. It aggregates several independent frameworks, each with its own reference text, body and deliverables. None waives the others.
| Strand | Main framework | Market | Detailed guide |
|---|---|---|---|
| Radio | RED art. 3.2, FCC Part 15.247, RSS-247 | EU, US, Canada | fcc-id-grantee-tcb-equipment-authorization |
| Bluetooth brand | Bluetooth SIG qualification | Global | bluetooth-sig-qualification |
| Exposure (SAR) | EN 50566, IEC 62209-2 | EU, US, Canada | sar-procedures-iec-62209-en-50360 |
| Product safety | IEC 62368-1 | Global | iec-62368-1-safety-engineering |
| Battery | IEC 62133-2, UN 38.3 | Global | iec-62133-un-38-3-battery-safety-transport |
| Cybersecurity | CRA, EN 18031 | EU | cyber-resilience-act-cra |
| Environment | RoHS, REACH, WEEE | EU | rohs-restriction-hazardous-substances |
To understand the sequence and timeline of these files, start from certification-getting-started and certification-timeline.
The radio strand: RED, FCC, ISED
Section titled “The radio strand: RED, FCC, ISED”A BLE wearable transmits in the 2.4 GHz ISM band, around 2400 to 2483.5 MHz, using frequency hopping or spread-spectrum modulation. That single fact triggers the radio regulation of every destination country.
European Union (RED)
Section titled “European Union (RED)”In the EU, the equipment falls under the Directive 2014/53/EU (RED). Three essential requirements apply:
- Article 3.1(a): safety and health (covers electrical safety and SAR).
- Article 3.1(b): electromagnetic compatibility, assessed via EN 301 489-1 and EN 301 489-17.
- Article 3.2: efficient use of the spectrum, assessed via EN 300 328 for the 2.4 GHz band.
Since August 2025, article 3.3(d)(e)(f) adds radio cybersecurity requirements operationalised by the EN 18031 standard. It all concludes with an EU declaration of conformity and the CE mark. The skeleton of your test plan is prepared with red-checklist and cert-test-plan-template.
United States (FCC) and Canada (ISED)
Section titled “United States (FCC) and Canada (ISED)”In the US, the radio falls under FCC Part 15.247 (spread-spectrum devices, ISM bands) and leads to an FCC ID issued through a Telecommunication Certification Body. In Canada, the equivalent is ISED's RSS-247 standard, leading to a certification (IC) number. The testing is largely shareable between the two countries.
| Item | EU (RED) | US (FCC) | Canada (ISED) |
|---|---|---|---|
| Reference text | Directive 2014/53/EU | 47 CFR Part 15.247 | RSS-247 |
| Spectrum standard | EN 300 328 | FCC Part 15.247 | RSS-247 |
| Outcome | CE mark, DoC | FCC ID | IC number |
| Body | Self-declaration, NB if needed | TCB | ISED, recognised TCB |
| Detail | red-checklist | fcc-id-grantee-tcb-equipment-authorization | ised-canada-radio-certification |
The vast majority of wearables integrate a pre-certified BLE module (Nordic, Silicon Labs, u-blox, and others). That module already carries its FCC ID, its IC number and a Bluetooth QDID. The finished product inherits these authorisations under strict integration conditions (same antenna, same placement, compatible firmware). Compare the approaches in ce-vs-fcc-emc and eu-us-dual-certification.
Bluetooth SIG qualification
Section titled “Bluetooth SIG qualification”Bluetooth SIG qualification is a private brand-licence programme, unrelated to public radio. Without it, a product cannot use the Bluetooth name, display the logo, or join the Apple Find My, Google Fast Pair or Matter ecosystems.
Two main routes exist:
- End Product Listing (EPL): reuse of an already-qualified design (the module QDID) with a reduced-fee Declaration ID. This is the standard route for a wearable built on a module.
- Full qualification: for a new software stack or RF design, with interoperability testing and test-case selection via ICS and IXIT.
The detail of the programme, the membership tiers and the identifiers (QDID, Declaration ID) is in bluetooth-sig-qualification. Remember the principle: SIG qualification and radio compliance are two cumulative obligations.
Radio exposure: body-worn SAR
Section titled “Radio exposure: body-worn SAR”A wearable is worn against the body continuously, which puts the exposure question front and centre. SAR (specific absorption rate) measures the radiofrequency energy absorbed by tissue.
When is a measurement required ?
Section titled “When is a measurement required ?”A typical BLE wearable transmits at low power (often under 10 mW EIRP). At that level, an exemption from a detailed SAR assessment is common, provided it is documented and justified in the technical file. Higher-power transmitters, or devices worn in direct contact with the skin, may instead require a full measurement.
| Situation | EU | US / Canada |
|---|---|---|
| Low power, distance > threshold | Justified exemption | SAR exemption (RF exposure evaluation) |
| Body-worn, significant power | EN 50566, IEC 62209-2 | FCC OET Bulletin 65, KDB 447498 |
| Limb (wrist) | 4 W/kg over 10 g (limbs/extremities, EU and US) | 4 W/kg over 10 g (limbs/extremities, EU and US) |
The assessment method, the limits (2 W/kg in the EU over 10 g, 1.6 W/kg in the US over 1 g) and the documentation are detailed in sar-procedures-iec-62209-en-50360. Whether you measure or exempt, the rationale joins the technical documentation file.
Electrical safety and battery
Section titled “Electrical safety and battery”Product safety (IEC 62368-1)
Section titled “Product safety (IEC 62368-1)”A wearable is audio, video and information technology equipment within the meaning of IEC 62368-1. The standard supersedes the former IEC 60950-1 and IEC 60065 and rests on the hazard-based safety engineering (HBSE) approach. For a low-voltage battery-powered object, the analysis focuses mainly on the thermal and electrical energy sources tied to charging. See iec-62368-1-safety-engineering.
Lithium battery (IEC 62133-2, UN 38.3)
Section titled “Lithium battery (IEC 62133-2, UN 38.3)”The lithium-ion or lithium-polymer cell imposes two distinct families of tests:
- Cell and pack safety: IEC 62133-2 covers the safety tests (short circuit, overcharge, crush, thermal shock).
- Transport: UN 38.3 imposes eight tests (T1 to T8: altitude, thermal, vibration, shock, external short circuit, impact, overcharge, forced discharge) before any air or sea shipment.
In the EU, Regulation (EU) 2023/1542 on batteries adds labelling obligations (sorting pictogram, capacity marking), durability obligations and, in time, a battery passport. The detail of the testing is in iec-62133-un-38-3-battery-safety-transport and the EU battery compliance in eu-battery-regulation. For shipping, see hazmat-imdg-iata-lithium-shipping.
Cybersecurity: RED 3.3, CRA and EN 303 645
Section titled “Cybersecurity: RED 3.3, CRA and EN 303 645”A connected wearable handles sensitive personal data (heart rate, location, sleep) and exposes a firmware and radio attack surface. Two frameworks overlap in the EU.
- RED article 3.3: since August 2025, the EN 18031 standard operationalises the requirements for network protection, personal-data protection and fraud prevention for any connected radio equipment.
- Cyber Resilience Act: the CRA (Regulation (EU) 2024/2847) covers products with digital elements, with essential requirements fully applicable at the end of 2027, including vulnerability management and security updates.
The EN 303 645 standard, ETSI's baseline for consumer IoT cybersecurity, serves as a good-practice foundation (no default passwords, minimised attack surface, signed updates). See en-303-645-iot-cybersecurity and cyber-resilience-act-cra. A structured risk analysis, for example via risk-management-iso-14971-iec-31010-fmea-fta, underpins both frameworks.
Environment: RoHS, REACH, WEEE, batteries
Section titled “Environment: RoHS, REACH, WEEE, batteries”Like any electronic equipment placed on the EU market, the wearable must satisfy product environmental law.
| Framework | Object | Deliverable | Guide |
|---|---|---|---|
| RoHS | Restriction of hazardous substances | Included in the DoC, EN IEC 63000 | rohs-restriction-hazardous-substances |
| REACH | Chemical substances, SVHC | SCIP / supply-chain information | reach-chemical-substances-svhc |
| WEEE | Electronic waste | Crossed-out bin pictogram, compliance scheme | weee-electronics-waste-eu |
| Batteries 2023/1542 | Batteries and waste batteries | Labelling, collection | eu-battery-regulation |
For US markets, California Proposition 65 may impose a substances warning. See california-prop-65-warnings.
Wellness or medical device: the decision table
Section titled “Wellness or medical device: the decision table”This is the structuring question for a wearable measuring physiological signals. The boundary turns not on the hardware but on the claimed intended purpose within the meaning of Regulation 2017/745 (MDR).
| Product claim | Regime | Framework |
|---|---|---|
| Step count, calories, consumer sleep | Wellness, consumer product | CE radio + safety, no MDR |
| Heart rate for information only | Wellness (generally) | CE consumer |
| Detection or alert of an arrhythmia (AFib) | Medical device | MDR, class IIa likely |
| SpO2 measurement for a diagnostic purpose | Medical device | MDR |
| Patient monitoring under prescription | Medical device | MDR + quality |
As soon as a claim invokes the diagnosis, prevention, monitoring or treatment of a condition, the product enters the scope of the MDR and must follow a distinct path: classification, quality system, clinical evaluation, notified body. See mdr-medical-device-regulation, and for medical electrical safety iec-60601-1-medical-electrical-safety. The full case of a product crossing this line is covered in certification-medical-wearable.
Market-entry checklist
Section titled “Market-entry checklist”A condensed procedure for a wellness BLE wearable bound for the EU, the US and Canada:
- Frame the intended purpose. Check that no claim tips the device into a medical device (table above).
- Choose the BLE module. Favour a pre-certified module (FCC ID, IC, QDID) to share the radio strand.
- Radio. EN 300 328 + EN 301 489 (EU), FCC Part 15.247, RSS-247; obtain the FCC ID and IC number.
- Bluetooth SIG. Join the SIG, declare the product (EPL if the module is qualified).
- SAR. Measure or justify a body-worn exemption, document it in the file.
- Safety. Assess IEC 62368-1; have the battery covered by IEC 62133-2 and UN 38.3.
- Cyber. Implement EN 18031 (RED 3.3) and prepare CRA compliance.
- Environment. RoHS (EN IEC 63000), REACH/SCIP, WEEE, battery labelling 2023/1542.
- Documentation. Compile the technical documentation file and sign the EU declaration of conformity.
- Marking. Apply CE, the FCC ID, the IC number and the environmental pictograms.
To estimate the overall budget, see certification-costs.
Common pitfalls
Section titled “Common pitfalls”| Pitfall | Consequence | Fix |
|---|---|---|
| Believing Bluetooth qualification covers the radio | Illegal placing on the market | Treat SIG and radio as two separate files |
| Forgetting body-worn SAR | Incomplete RED file, rejection | Measure or justify an exemption, document it |
| Changing pre-certified module firmware without checking | Loss of FCC ID / IC validity | Verify the module integration conditions |
| Ignoring UN 38.3 before shipment | Logistics block, freight refused | Test the battery early in the project |
| Underestimating the CRA / EN 18031 timeline | Cyber non-compliant product | Build cyber in from design |
| A medical-purpose marketing claim | Unanticipated MDR tip-over | Validate every claim against the decision table |
| Neglecting WEEE and battery labelling | Customs refusal or recall | Include the pictograms from the packaging stage |
