Difference Between CE-LVD and CE-EMC Testing

For selling electronic and electrical products in the EU market, CE certification is an essential pass. Whether on Amazon or other e-commerce platforms, products are required to have both CE-LVD and CE-emc certification qualifications. So, what are the differences between these two? How can certification be efficiently completed?

Definitions and Core Objectives of CE-LVD and CE-EMC

CE-LVD (low voltage directive)

- Applicable voltage range: Electrical equipment operating at AC 50V-1500V, DC 75V-1500V.

- Core objective: Ensure that under normal or fault conditions, the device will not cause electric shock, fire, or mechanical injury, thus protecting user safety.

CE-EMC (Electromagnetic Compatibility Directive)

- Core objective: Ensure that the device neither interferes with other equipment (EMI) nor is disturbed by external electromagnetic interference (EMS), guaranteeing stable operation.

Comparison of Test Contents: Safety vs. Compatibility

CE-LVD

- Test Focus: Electrical and mechanical safety

- Typical Tests: Insulation resistance, grounding continuity, leakage current, temperature rise test, protection level

CE-EMC

- Test Focus: Electromagnetic compatibility

- Typical Tests: Conducted emissions, radiated emissions, electrostatic discharge immunity, harmonic and voltage flicker tests, surge immunity, power frequency magnetic field immunity, voltage dip tests, etc.

Differences in Scope

- CE-LVD:Applies to all equipment operating within the rated voltage range, such as household appliances, lighting, power tools, medical devices, etc.

- CE-EMC:Covers a broader range including industrial equipment, consumer devices, multimedia devices, household appliances, and lighting. Passive components (e.g., resistors, capacitors) generally do not require certification.

Regulation Updates and Validity

- CE certification has no fixed validity period but must be re-evaluated following updates in EU regulations.

- LVD Directive: 2014/35/EU

- EMC Directive: 2014/30/EU

CE-LVD ensures product safety, while CE-EMC guarantees electromagnetic compatibility—both are indispensable. Before listing on EU e-commerce platforms (such as Amazon), be sure to complete both certifications.
