    TWS headset CE-RED certification——ZRLK

    Author:中認聯科 time:2021-12-10 Ctr:1912

    TWS adopts a bilateral working mode, which enables wireless headsets to achieve true stereo sound. It not only allows the wireless headset to play the sound on the left and right channels, but also achieves stability and low latency, making people feel like they are on the scene. However, if such products want to be exported to the EU market, CE certification is required.

    CE certification is a license to enter the EU market

    CE certification provides a unified technical specification for products of various countries to trade in the European market and simplifies the trade procedures. Any country's products must be CE certified to enter the European Union and the European Free Trade Area, and the CE mark should be affixed to the product. Therefore, CE certification is a passport for products to enter the European Union and European Free Trade Zone countries.

    TWS headset CE-RED certification test project

    1. The CE testing standards and items required for TWS headsets include EMC testing, RF testing, SAR evaluation, and LVD testing;

    2. EMC tests whether the headset conforms to the CE directive on electromagnetic compatibility standards;

    3. The RF test is aimed at the test of radio communication products. Since the wireless headset adopts wireless Bluetooth technology, it must meet the requirements of CE-RF;

    4. SAR is the electromagnetic wave absorption ratio, which is aimed at the safety and health protection requirements of electronic and electrical products;

    5. The LVD test is a low voltage directive to ensure that the equipment is safe to use in low voltage conditions. The part with a charging box also needs to meet the requirements of the LVD directive.

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

    1. User manual; circuit schematic diagram;

    2. Circuit block diagram (BlockDiagram, also called module function diagram);

    3. Circuit layout diagram (PCBLAYOUT); circuit location number diagram (PCBplacement);

    4. Operation description (an explanation of the block diagram); component list (BOMLIST);

    5. Label; antenna specifications (or antenna gain diagram);

    6. Charger LVD report; fixed-frequency software (also called fixed-frequency program, so that 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 process

    1. Project application: submit an application for CE certification to ZRLK testing;

    2. Document preparation: According to CE certification requirements, the company prepares relevant certification documents and materials;

    3. Product testing: The company sends samples to the ZRLK testing laboratory for product testing;

    4. Preparation of reports: ZRLK certified engineers compile reports based on the qualified test data;

    5. Submit for review: ZRLK engineers will review the complete report;

    6. Certificate issuance: CE certification will be issued after the report is verified.
