    TWS Bluetooth headset CE certification——ZRLK

    Author:中認(rèn)聯(lián)科 time:2021-02-03 Ctr:1523

    With the continuous development of technology, more and more mobile phones gradually cancel the 3.5mm headphone jack, making wireless headsets gradually become one of the must-haves of digital products. TWS Bluetooth headset enables wireless headsets to achieve true stereo sound, allowing wireless headsets to achieve left and right 2 channels of sound playback, while also achieving stability and low latency, making people feel like they are on the scene. In the European market, TWS Bluetooth headsets are also one of the most popular best-selling products in the headsets, but CE certification is used as an access certificate for the European Union market, and wireless headsets and headset charging boxes that want to export to the EU need to obtain CE certification.

    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 certification fee

    The cost of CE certification is related to the product model, and needs to be evaluated according to the specific headset specifications, such as the mode of the BT module, whether to bring a charging box, etc.

    TWS headset CE test project

    The CE test standards and items that TWS headphones need to do include EMC testing, RF testing, SAR evaluation, and LVD testing.

    EMC tests whether the headset meets the CE Directive on electromagnetic compatibility standards:

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

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

    ◆ LVD test is a low voltage instruction 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 instruction.

    1. Fill in the CE application form

    2. Provide product information and send samples to the testing laboratory

    3. The laboratory arranges the test

    4. After the test report is qualified, a CE certificate will be issued

    It should be noted that if the test fails and needs to be re-tested, this area generally requires rectification.
