What is a CE EMC Test Report?

Electromagnetic Compatibility (EMC) testing is a key requirement for obtaining CE certification for electronic products. In China, JJR Laboratory offers services for handling CE certification, including emc testing. The cost of emc testing depends on the specific requirements and characteristics of the product.

EMC is a comprehensive assessment of the electromagnetic interference (EMI) a product generates and its electromagnetic susceptibility (EMS). It is a critical indicator of product quality, involving measurements conducted using specialized testing facilities and instruments. Given the variety of standard testing items under EMC and low voltage directive (LVD), JJR Laboratory engineers tailor the testing projects and provide corresponding quotes based on the product's characteristics and needs.

EMC Directive Requirements for CE Certification

Certain products only need to comply with the CE-EMC directive for CE certification. However, if a product operates at a voltage range of AC (50–1000V) or DC (75–1500V), it must also comply with the safety-related CE-lvd directive. The costs of these certifications vary significantly. Machinery products, for instance, incur higher ce certification costs than ordinary products due to the need for factory inspections and evaluations.

Components of EMC Testing

EMC consists of two main parts:

1. EMI (Electromagnetic Interference):

 - Radiated Emission (RE)

 - Conducted Emission (CE)

 - Harmonics

 - Flicker

2. EMS (Electromagnetic Susceptibility):

 - Electrostatic Discharge (ESD)

 - Electrical Fast Transient (EFT)

 - Voltage Dips (DIP)

 - Conducted Susceptibility (CS)

 - Radiated Susceptibility (RS)

 - Surge (Lightning) Immunity

Additional standards include:

- Harmonic Current: IEC61000-3-2, EN61000-3-2

- Voltage Flicker: IEC61000-3-3, EN61000-3-3

Documents Required for EMC Certification

To conduct EMC testing and obtain certification, the following materials are needed:

1. Two fully functional product samples (preferably larger or more complex products).

2. Product manual.

3. Circuit diagram (needed if the product fails initial testing).

If the EMC test is successful, the certification process can be completed within 5–7 working days, and the certificate will be issued.
