Acoustic EMC electromagnetic compatibility test handling——ZRLK

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.
