    CE certification of Bluetooth keyboard——ZRLK

    Author:中認聯(lián)科 time:2022-12-05 Ctr:968

    The Bluetooth keyboard refers to the keyboard that carries out wireless transmission through the Bluetooth protocol and carries out Bluetooth communication within the effective range (10m). Because the Bluetooth keyboard is wireless and easy to carry and use, it is popular among consumers. However, whether the Bluetooth keyboard is exported separately or exported together to enter the EU market, CE certification is required. Common keyboard CE certification testing instructions are electromagnetic compatibility CE-EMC and low-voltage CE-LVD instructions; For CE certification of Bluetooth keyboard, the wireless CE-RED command needs to be detected.

    6. Nameplate (font, CE symbol);

    7. Product operation manual, installation and maintenance (English version);

    8. Parts list (product name CE certification, manufacturer).

    CE Certification Process of Bluetooth Keyboard

    1. Project application - submit the test application to the supervision of ZRLK testing agency.

    2. Data preparation: according to the CE certification requirements, the enterprise shall prepare relevant certification documents.

    3. Product testing - the enterprise sends the samples to be tested to the laboratory for testing.

    4. Preparation of report - The certification engineer shall prepare the report according to the qualified test data.

    5. Submit for review - The engineer will review the complete report.

    6. Issuing certificate - CE certification certificate will be issued after the report is verified to be correct.
