    Audio specifically refers to an audio system that produces sound from a combination of electrical equipment. Audio export to the EU needs to apply for a CE certification clearance certificate, and speakers for CE certification for EMC electromagnetic compatibility and LVD low voltage testing.

    Audio CE certification EMI (electromagnetic interference) can be divided into:

    1. Radiation: space radiation; power radiation; open field test;

    2. Conduction: power supply harmonics (Harmonic voltage flickers.

    Audio CE certification EMS (electromagnetic tolerance) can be divided into:

    1. ESD (electrostatic radiation resistance test);

    2. EFT (impulse noise resistance test);

    3. SURGE (lightning resistance surge test);

    4. RS (resistance to radio frequency radiation test);

    5. CS (resistance to radio frequency conduction test);

    6. Magnetic Field (power frequency magnetic field test);

    7. DIP (withstand voltage change test);

    8. Resistance to low-frequency conductivity interference to ac power input;

    9. Resistance to continuous conductivity interference from dc to 150KHz.

    Audio CE certification LVD safety test

    1. Power input test;

    2. Label durability test;

    3. Dangerous energy test;

    4. Capacitor discharge test of a circuit;

    5. Current circuit test ground resistance test;

    6. Wet treatment test;

    7. Power cord stress relief test;

    8. Impact test drop test;

    9. Temperature rise test;

    10. Ball pressure test working voltage, electrical clearance and creepage distance test;

    11. Regular work test;

    12. Electric strength test.

    Process audio EMC certification

    1. Project application-submit an application to the inspection agency supervision.

    2. Data preparation-according to the standard requirements, the company prepares the relevant certification documents.

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

    4. Compilation report-The certified engineer compiles the report based on the qualified test data.

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

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