        Wireless headset RED certification test project——ZRLK

        Author:中認聯(lián)科 time:2021-01-27 Ctr:2357

        In recent years, with the improvement of people's consumption level, the sales market of wireless headsets has also become larger and larger. Compared with wired earphones, wireless earphones have little difference in sound quality, but wireless is more convenient, mainly because the middle line is replaced by electric waves. The wireless earphone is the middle wire is replaced by the electric wave, which is connected from the audio outlet of the computer to the transmitting end, and then sent from the transmitting end to the earphone at the receiving end through electric waves. However, the export of wireless products such as wireless headphones to Europe requires CE-RED certification.

        Introduction to RED certification

        The 1999/5/EC directive has been implemented for many years, and many places cannot meet the requirements of existing products. 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 EU’s new CE framework resolution 768/2008/EC. RED 2014/53/EU replaces the original European Union Radio Equipment Directive R&TTE-D 1999/5/EC.

        RED certification test items

        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 notification of European permitted spectrum (Notification);

        5. CTR (TBR) test;

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

        Significant differences between the new wireless equipment directive (RED) and the old R&TTE directive

        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";
