How to get a CE Certification for TWS Bluetooth Earbuds?

Applying for CE certification for TWS (True Wireless Stereo) Bluetooth earbuds is a complex but systematic process aimed at ensuring that the product complies with the safety, health, and environmental requirements of the European Union (EU) market.

Identify Applicable Directives and Standards

TWS Bluetooth earbuds must comply with several EU directives and standards, including:

1.1 Radio Equipment Directive (RED, 2014/53/EU):  

Covers safety, health, and electromagnetic compatibility (EMC) requirements for radio equipment.

1.2 Low Voltage Directive (LVD, 2014/35/EU):  

Applies to electrical equipment with a rated voltage between 50V and 1000V AC and between 75V and 1500V DC. While TWS earbuds generally operate at lower voltages, some charging equipment may need to comply with this directive.

1.3 Electromagnetic Compatibility Directive (EMC, 2014/30/EU):  

Ensures that the device does not generate excessive electromagnetic interference and is resistant to such interference.

1.4 RoHS Directive (2011/65/EU):  

Restricts the use of certain hazardous substances.

Product Testing and Evaluation

Conduct testing and evaluation according to the applicable directives:

- Internal Testing:  

  Manufacturers can perform pre-assessments internally to ensure basic compliance.

- External Testing:  

  Formal testing by a third-party laboratory is a key step in ensuring product compliance. This testing includes radio performance, electromagnetic compatibility, safety, and restrictions on hazardous substances.

Prepare Technical Documentation

Prepare detailed technical documentation (Technical Construction File, TCF) that includes:

3.1 Product description  

3.2 Design and manufacturing drawings  

3.3 Electrical schematics  

3.4 Risk assessment report  

3.5 Test reports  

3.6 User manual and safety information  

Determine the Conformity Assessment Route

Select the appropriate conformity assessment route based on the complexity and risk level of the product:

4.1 Self-Declaration:  

Suitable for low-risk products, where the manufacturer can carry out the conformity assessment themselves.

4.2 Notified Body Involvement:  

High-risk products typically require assessment and certification by an EU Notified Body.

Conformity Assessment and Testing

5.1 Self-Assessment:  

If applicable, the manufacturer evaluates the product’s conformity based on technical documentation and test results.

5.2 Notified Body Assessment:  

If required, engage a Notified Body for evaluation and testing to obtain the relevant certificates and reports. For TWS Bluetooth earbuds, this often involves Notified Body participation, particularly for radio performance assessment.

Sign the Declaration of Conformity (DoC)

The manufacturer must sign the EU Declaration of Conformity (DoC), confirming that the product meets all relevant directives and standards. The DoC should include:

6.1 Manufacturer’s name and address  

6.2 Product description and identification  

6.3 Applicable directives and standards  

6.4 Name, position, and signature of the signatory  

Affix the CE Marking

After signing the Declaration of Conformity, the CE marking can be affixed to the product. The CE mark must comply with the specified size and format requirements, ensuring it is clearly visible.

Retain Technical Documentation

Manufacturers must retain the technical documentation for at least 10 years, in case of inspection by EU market surveillance authorities. This documentation should include all test reports, technical files, and the Declaration of Conformity.

Maintain Ongoing Compliance

Ensure that the product continues to comply with CE certification requirements throughout its lifecycle, including regularly updating technical documentation and maintaining product quality. Manufacturers should establish a continuous quality management system to monitor product consistency.

Example Process Flow

1. Identify directives and standards  

2. Product testing and evaluation  

3. Prepare technical documentation  

4. Select assessment route  

5. Conformity assessment and testing  

6. Sign Declaration of Conformity  

7. Affix CE marking  

8. Retain technical documentation  

9. Maintain ongoing compliance

TWS Bluetooth earbuds application for CE certification is a detailed and rigorous process, involving adherence to multiple EU directives and standards. Manufacturers must conduct thorough product testing and evaluation, prepare comprehensive technical documentation, and perform conformity assessments through appropriate channels. After signing the Declaration of Conformity, the product can bear the CE marking and be sold in the EU market. Ensuring ongoing compliance and quality management is key to long-term success for manufacturers. By following these steps, manufacturers can effectively complete the CE certification process, ensuring their products meet EU market requirements.
