TWS earphones do not have traditional physical wires. The left and right earphones form a stereo system through Bluetooth. The mobile phone can be connected to one receiving end. This receiving end will divide the stereo into another receiving end through wireless transmission to form a stereo system. TWS earphones are widely loved by people once they come out with the product's novel design, complete and rich functions, and convenient and quick operation. The future market development potential will also be huge. However, if TWS headsets want to enter the EU market, they need to apply for CE-RED certification.

What is CE-RED certification?

The 1999/5/EC directive has been implemented for many years, and existing products cannot be satisfied in many places. On May 22, 2014, the European Union officially announced a new version of the wireless equipment directive RED 2014/53/EU. This directive is based on the European Union’s new CE framework resolution 768/2008/EC. RED 2014/53/EU replaces the original The European Union Radio Equipment Directive R&TTE-D 1999/5/EC. For wireless products sold in the EU market, EU member states will adopt the New Radio Equipment Directive (RED) from June 13, 2016; wireless products that comply with the old R&RTTE Directive will be prohibited from being sold on the EU market.

TWS headset CE-RED certification test corresponding standards

Electrical Safety (LVD): EN 62368-1:2014+A11:2017.

Electromagnetic compatibility (EMC): EN 301489-1 V2.2.3 (General Provisions), EN 301489-17 V3.2.0 (Bluetooth, WALN).

Radio Frequency (RF): EN 300328 V2.2.2.

Health (SAR): EN 62479:2010 (or EN 50663:2017, less than 20mW can be excluded).

TWS headset CE-RED certification test project

1. Electromagnetic compatibility test (EMC test)

2. Safety test LVD (in the new directive, this test is also required for battery input RF products)

3. Perform radio communication equipment testing (RF testing) according to European ETSI standards

4. Information Announcement of European Permitted Spectrum (Notification)

5. CTR (TBR) test

6. Electrical safety and health protection test (SAR evaluation)

Materials to be prepared for CE-RED certification of TWS headset

1. User manual

2. Circuit schematic diagram

3. Circuit block diagram (Block Diagram, also called module function diagram)

4. Circuit layout (PCB LAYOUT)

5. PCB placement

6. Operation description (explanation of block diagram)

7. BOM LIST

8, label (label)

9. Antenna specifications (or antenna gain diagram)

10. Charger LVD report

11. Fixed frequency software (also called fixed frequency program. The transmitter module can be set to transmit continuously at a certain frequency point, generally BT and WIFI must be provided)

TWS headset CE-RED certification application process

1. Preliminary consultation (consult the designated testing agency)

2. Document preparation (prepare information according to the instructions, fill in the application form, and provide product description information)

3. Product testing (send the product to the laboratory, test the sample data, send the sample to the staff in time, provide product manuals, drawings, technical parameters, etc.)

4. Audit (the certification body reviews the test report)

5. Certificate issuance (certificate sent after approval)
