Sound is a common electrical equipment, especially a set of audio system that combines electrical equipment to produce sound. Its basic composition roughly includes: sound source (CD, VCD, DVD, MD, MP3, etc.), power amplifier (including front amplifier and power amplifier), speaker (including surround speaker, center speaker, main speaker and subwoofer), etc. However, if such products want to be exported to the European market, they need to apply for CE certification, EMC electromagnetic compatibility and LVD low-voltage test.

Audio CE certification test standard

Harmonized standard for EMI (electromagnetic interference) test: EN55013

Harmonized standard for EMS (electromagnetic withstand) test: EN55020

LVD low-voltage test coordination standard: EN60065

Audio CE certification EMC electromagnetic compatibility test project

EMI (electromagnetic interference) test items

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

2. Conduction: power harmonic (Harmonic voltage flickers).

EMS (electromagnetic withstand) test items

1. ESD (static radiation resistance test);

2. EFT (pulse noise resistance test);

3. SURGE lightning surge resistance test);

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

Audio CE certification LVD low voltage test project

1. Power input test; Label durability test;

2. Hazardous energy test; Capacitor discharge test of primary circuit;

3. Current circuit test, grounding resistance test; Humidity treatment test;

4. Power line stress relief test; Impact test and drop test;

5. Temperature rise test; Ball pressure test working voltage, electrical clearance and creepage distance test;

6. Constant working test; Dielectric strength test.

Materials to be prepared for audio CE certification application

1. Circuit schematic diagram&PCB layout diagram;

2. Product manual and product nameplate;

3. Product working principle diagram and block diagram;

4. List of key components (wires, plugs, fuses, varistors, optocouplers, X/Y capacitors, transformers, enclosures, etc.);

5. Product BOM;

6. Product related specifications.

Audio CE Certification Process

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

2. Data preparation: according to the standard 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.
