CE Compliance Testing

As is well known, CE certification is a mandatory requirement in the European Union (EU). Most products entering the EU market must comply with CE standards. Common electronic and electrical products requiring CE certification include household appliances, IT/AV products, lighting products, wireless or communication terminal devices, and mechanical equipment.

So, what are the main tests for these products when exporting to Europe for CE certification? What are the testing objectives?

Key ce testing Categories for Electronic and Electrical Products

1. EMC (Electromagnetic Compatibility) Testing

The purpose of emc testing is to evaluate the electromagnetic radiation emitted by electrical products and its impact on humans, public power grids, and other electronic devices operating normally. EMC consists of two main aspects:

- EMI (Electromagnetic Interference): Focuses on the interference caused by the device. Tests include:

- RE (Radiated Emission)

- CE (Conducted Emission)

- Harmonic Distortion

- Flicker

- EMS (Electromagnetic Susceptibility/Immunity): Evaluates the device's resistance to external electromagnetic disturbances. Tests include:

- ESD (Electrostatic Discharge)

- EFT (Electrical Fast Transients)

- DIP (Voltage Dips and Interruptions)

- CS (Conducted Immunity)

- RS (Radiated Immunity)

- Surge (Lightning and Power Surges)

2. LVD (low voltage directive) Testing

LVD testing ensures the safety of a product under normal operating conditions, reducing risks to individuals, buildings, and property. Key LVD tests include:

- Grounding Test

- Insulation Test

- Temperature Rise Test

- Leakage Current Test

- Mechanical Safety Tests

3. RF (Radio Frequency) Testing

RF testing ensures that wireless communication devices meet the relevant performance standards and regulations to guarantee communication quality and stability. Key RF tests include:

- Transmitting Power Test (Conducted and Radiated Methods)

- Transient Power Test

- Adjacent and Alternate Channel Power Test

- Broadband Emission Test

- Spectral Characteristics Test

- Frequency Error and Phase Error Test

- Spurious Emissions Test (Conducted and Radiated Methods)

- Maximum Usable Sensitivity Test

- Adjacent Channel Selectivity Test

- Blocking Test

- Co-channel Rejection Test

- Spurious Response Rejection Test

- Intermodulation Rejection Test

- SAR (Specific Absorption Rate) Test

The above are the common CE testing categories for electronic and electrical products. Depending on the product's function, voltage, and technical specifications, testing standards and methods may vary. The testing content and approach should be tailored to the product's characteristics and actual requirements.
