More Introduction

1. Introduction to EMC Certification

EMC (Electro Magnetic Compatibility) refers to the ability of a device or system to operate compliantly in its electromagnetic environment without causing intolerable electromagnetic interference to any device in its environment. Therefore, EMC includes two requirements: on the one hand, it means that the electromagnetic interference generated by the equipment to the environment in the normal operation process cannot exceed a certain limit; degree of immunity, ie electromagnetic susceptibility. EMC certification is a directive on electromagnetic compatibility in CE certification.

3. EMC certification process

Step 1: Application (1. Fill in the application form; 2. Provide information and send samples);

Step 2: Quote (according to the information you provide, an engineer will formulate the corresponding standard, test time and corresponding cost);

Step 3: Payment (After the applicant confirms the quotation, signs the application form and service agreement and pays the payment);

Step 4: Testing (the laboratory will conduct a full set of tests on the applied product according to the relevant EU testing standards);

Step 5: The test is passed and the report is completed;

Step 6: The project is completed and CE certificate is issued.

 

4. Items to be tested for EMC certification

Items

Conduction (9kHz-30MHz)

Radiated immunity (below 1GHz)

Power radiation (30MHz-300MHz)

Radiated immunity (above 1GHz)

Magnetic field radiation (9kHz-30MHz)

Fast burst EFT/B (±0.1-±4.4kV)

Space radiation (30MHz-18GHz)

Surge (0.1-6.6kV)

Intermittent Conducted Disturbance

Conducted immunity CS (0.1-30V)

harmonic

Anti-magnetic field interference MS (0-120A/m)

Voltage flashes

Power off Dips (0%-100%)

Electrostatic ESD (±0.1-±16.5kV)

Oscillating surge (0.1-6.6kV)

Magnetic Field (EFM 10Hz-400kHz)

Harmonic, interharmonic anti-interference, etc.

 

5. CE-EMC certification validity period

In the case that the product design, regulations and instructions have not changed, the CE-EMC certification report can always be valid, unless the buyer has special requirements.
