In recent years, with the rapid development of technology, electronic products have gradually moved towards intelligent development. Products such as Bluetooth speakers, Bluetooth headsets, Bluetooth watches, smart homes, etc. have gradually become popular. However, for any product to be sold in the market, there will be corresponding certification regulations. We all know that electronic and electrical products entering the EU market require mandatory CE certification. CE certification for wireless products such as Bluetooth watches is also called RTTE certification. Certification Directive 1995/5 /EC, on May 22, 2014, the European Union announced a new version of the Radio Equipment Directive 2014/53/EU to replace the original Radio and Telecommunications Terminal Equipment Directive 1995/5/EC, and the RTTE certification was also updated to CE -RED certification.

The major differences between the new wireless equipment directive (RED) and the old R&TTE directive are:

1. RED product range only includes wireless communication and wireless identification equipment (such as RFID, radar, motion detection, etc.). Radio frequency equipment that is not used for communication or identification will be under the control of the electromagnetic compatibility EMC directive and the low voltage LVD directive;

2. Wired communication terminal equipment (TTE) is removed, so the RED instruction is only used for wireless products;

3. The radio broadcast receiver has now been included in the scope of the RED directive (previously covered in the electromagnetic compatibility EMC directive and low voltage LVD directive);

4. The lower limit of the instruction coverage frequency has been cancelled (previously, R&TTE's control starting frequency was 9 kHz), and the upper limit is still 3000 GHz;

5. The evaluation opinions of the notified body have been replaced by the "type inspection certificate".

CE-RED test items

1. Electromagnetic compatibility test (EMC test);

2. Safety low voltage instruction test (LVD test);

3. Radio communication equipment test (RF test);

4. Magnetic field radiation test (EMF test/SAR test).

Information required for CE-RED certification

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 (an explanation of the 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 fixed at a certain frequency point for continuous transmission, generally BT and WIFI must be provided).
