Display Screen EU CE Certification

As international markets expand, monitors play a critical role as an essential component of electronic products. Their compliance is key to entering the EU market. To ensure products meet relevant EU directives, monitors must obtain CE certification. This article by China JJR Laboratory provides a detailed overview of the CE certification testing items and corresponding standards for monitors.

Overview of CE Certification

CE certification is a fundamental safety certification required by the EU for products entering its market, indicating compliance with relevant EU directives. For monitors, the main directives involved are:

- EMC Directive (Electromagnetic Compatibility): Ensures that electronic devices have acceptable levels of electromagnetic interference and adequate resistance to external electromagnetic interference.

- LVD Directive (Low Voltage): Ensures electrical safety.

- erp directive (Energy-Related Products): Ensures energy efficiency and environmental requirements.

- RoHS Directive: Restricts the use of hazardous substances.

CE Certification Testing Items for Monitors

1. EMC (Electromagnetic Compatibility) Testing

Monitors must meet electromagnetic compatibility requirements. Specific tests include:

- Radiated Emissions Testing: Measures electromagnetic radiation from monitors during operation (standard: EN 55032).

- Conducted Emissions Testing: Examines electromagnetic interference conducted via power lines.

- Immunity Tests:

- Electrostatic Discharge (ESD) Immunity Test (EN 61000-4-2)

- Radiated Immunity Test (EN 61000-4-3)

- Electrical Fast Transient/Burst (EFT) Immunity Test (EN 61000-4-4)

- Surge Immunity Test (EN 61000-4-5)

- Conducted Immunity Test (EN 61000-4-6)

- Voltage Dips and Short Interruptions Immunity Test (EN 61000-4-11)

2. LVD (Low Voltage) Testing

Electrical Safety Tests:

- Leakage Current Test

- High Voltage Test (Dielectric Strength Test)

- Insulation Resistance Test

Mechanical Structure Tests:

- Evaluates the casing for effective protection against electric shock or other hazards.

- Temperature Rise Test: Ensures operating temperatures remain within safe limits.

- Ground Continuity Test: Assesses the effectiveness of grounding protection.

3. ErP (Energy-Related Products) Directive Testing

- Standby Power Consumption Test: Measures standby mode power consumption in accordance with EN 50564.

- Energy Labeling: Ensures compliance with ErP labeling requirements.

4. RoHS (Restriction of Hazardous Substances) Testing

- Checks for hazardous substances like lead, mercury, and cadmium.

- Ensures environmental compliance based on EN 62321.

5. Environmental and Mechanical Testing

- Drop Test: Ensures the product remains intact during transportation.

- Vibration Test: Verifies resistance to vibration during transport or use.

- Humidity and Temperature Test: Assesses stability under high humidity and temperature conditions.

6. Radiation Safety Testing (if applicable)

- Monitors with lasers or special light sources require radiation safety testing to ensure safe exposure levels for humans.

Relevant Standards

Key standards involved in CE certification for monitors include:

- EMC Standards:

- EN 55032 (Electromagnetic Emissions for Multimedia Equipment)

- EN 55035 (Electromagnetic Immunity for Multimedia Equipment)

- EN 61000 Series (Electromagnetic Immunity Tests)

- LVD Standards:

- EN 62368-1 (Safety Requirements for Audio/Video and Information Technology Equipment)

- ErP Standards:

- EN 50564 (Methods for Measuring Standby Power Consumption)

- RoHS Standards:

- EN 62321 (Methods for Testing Hazardous Substances)

Certification Process

1. Preparation for Testing:

Enterprises must prepare samples and technical documents (e.g., circuit diagrams, structural diagrams).

2. Testing Execution:

Conduct testing through an authorized third-party laboratory (e.g., China JJR Laboratory).

3. Technical Document Review:

Prepare a complete Technical File, including test reports and a Declaration of Conformity (DoC).

4. CE Marking:

After passing the tests, affix the CE mark to the product.

Important Notes

- CE certification must be conducted through legitimate channels and qualified laboratories to ensure legal test results.

- Enterprises should stay updated on EU regulatory changes and adjust their products accordingly.

- After entering the EU market, retain all technical documents and test records for at least 10 years.

CE certification is the gateway for monitors to enter the EU market, involving rigorous testing and complex technical standards. Companies must prioritize product compliance to ensure lawful market entry and enhance brand competitiveness. For assistance or inquiries, consult professional service providers to help your monitors successfully achieve certification.
