As international markets continue to expand, monitors — as a key category of electronic products — must meet regulatory requirements in order to enter the EU market. To ensure that a product complies with the relevant EU directives, a monitor must obtain CE certification. This article provides a detailed explanation of the test items and corresponding standards involved in CE certification for monitors.
1. Introduction to CE Certification
CE certification is a fundamental safety certification established by the European Union for products entering its market. It indicates that a product meets the requirements of the relevant EU directives. For monitors, the following directives are primarily involved:
- EMC Directive (Electromagnetic Compatibility): Ensures that electromagnetic interference generated by electronic equipment remains within acceptable limits, and that the equipment itself has adequate immunity to electromagnetic disturbance.
- LVD (Low Voltage Directive): Ensures the electrical safety of electronic equipment.
- ErP Directive (Energy-related Products): Ensures that the product's energy efficiency and environmental performance meet the required standards.
- RoHS Directive: Restricts the use of hazardous substances.
2. CE Certification Test Items for Monitors
EMC (Electromagnetic Compatibility) Testing
Monitors must meet electromagnetic compatibility requirements. Specific tests include:
- Radiated emission testing: Checks whether the monitor generates excessive electromagnetic radiation during operation, in accordance with EN 55032.
- Conducted emission testing: Examines electromagnetic disturbance conducted through the power cord.
- Immunity testing:
- Electrostatic Discharge (ESD) immunity (EN 61000-4-2)
- Radiated RF immunity (EN 61000-4-3)
- Electrical Fast Transient/Burst (EFT/Burst) immunity (EN 61000-4-4)
- Surge (lightning) immunity (EN 61000-4-5)
- Conducted RF immunity (EN 61000-4-6)
- Voltage dips and short interruptions immunity (EN 61000-4-11)
LVD (Low Voltage) Testing
- Electrical safety testing: Leakage current test, high-voltage (dielectric withstand / hipot) test, insulation resistance test.
- Mechanical construction testing: Assesses whether the enclosure provides effective protection against electric shock or other hazards.
- Temperature rise test: Verifies that the monitor's temperature during operation remains within a safe range.
- Ground continuity test: Evaluates the effectiveness of the protective earthing.
ErP (Energy-related Products) Directive Testing
- Standby power consumption test: Verifies that the monitor's power consumption in standby mode complies with EU energy efficiency requirements, in accordance with EN 50564.
- Energy labelling: Ensures that the monitor meets the ErP labelling requirements.
RoHS (Restriction of Hazardous Substances) Testing
Checks whether the monitor contains hazardous substances — such as lead, mercury and cadmium — above the permitted limits, ensuring the product is environmentally compliant with the testing requirements of EN 62321.
Environmental and Mechanical Testing
- Drop test: Ensures the product will not be damaged by dropping during transportation.
- Vibration test: Verifies the monitor's resistance to vibration during transport or use.
- Humidity and temperature test: Tests the monitor's stability under high-humidity and high-temperature conditions.
Radiation Safety Testing (if applicable)
For monitors equipped with lasers or special light sources, radiation safety testing must be performed to ensure that optical radiation does not cause harm to the human body.
3. Standards Involved
Completing CE certification for monitors typically involves the following key standards:
- EMC standards: EN 55032 (emission requirements for multimedia equipment), EN 55035 (immunity requirements for multimedia equipment), EN 61000 series (electromagnetic immunity testing).
- LVD standards: EN 62368-1 (safety requirements for audio/video, information and communication technology equipment).
- ErP standards: EN 50564 (method for measuring standby power consumption).
- RoHS standards: EN 62321 (test methods for hazardous substances).
4. Certification Process
- Test preparation: The enterprise prepares samples and technical documentation (such as circuit diagrams and construction drawings).
- Test execution: Testing is carried out by a third-party laboratory such as Global United Technology Services (GTS).
- Technical file review: Prepare a complete Technical File, including the test report and the Declaration of Conformity (DoC).
- Affixing the CE marking: After passing the tests, the CE marking is applied to the product.
5. Important Notes
CE certification for monitors must be carried out through proper channels and qualified laboratories to ensure the legality of the test results. Enterprises should continuously follow updates to EU regulations and adjust their products promptly to comply with the latest requirements. After the product enters the EU market, all technical documentation and test records must be properly retained for at least 10 years.
6. Conclusion
CE certification is the passport for monitors to enter the EU market, and behind it lies a rigorous set of test items and complex technical standards. Enterprises must attach great importance to product compliance. Obtaining certification not only enables legal market access, but also enhances the brand's international competitiveness.
