CE certification standards and processing for electronic appliances

I. CE certification process for electronic appliances

1. Determine applicable directives and standards

According to the product type (such as household appliances, communication equipment, etc.), match the corresponding EU directives. Common directives include:

1) Low Voltage Directive (LVD 2014/35/EU): Applicable to electrical equipment with a voltage range of AC 50V-1000V or DC 75V-1500V.

2) Electromagnetic Compatibility Directive (EMC 2014/30/EU): Ensure that the product's electromagnetic radiation and anti-interference capabilities meet the standards.

3) Other directives that may be involved: such as the Machinery Directive (MD), the Ecodesign Directive, etc.

2. Risk assessment and testing

1) Self-declaration (low-risk products): Manufacturers can evaluate compliance and sign the "Declaration of Conformity" by themselves.

2) Third-party certification (high-risk products): Testing and review by domestic laboratories or EU Notified Bodies are required, including:

* Electrical safety tests (such as insulation strength, protection against electric shock);

* Electromagnetic compatibility tests (such as radiation interference, conducted interference);

* Environmental adaptability tests (such as temperature and humidity, mechanical vibration).

3. Application materials preparation

Application forms, product manuals, design drawings, parts lists, etc. must be provided.

4. Signing of Declaration of Conformity (DoC)

After the test is passed, the corporate legal person signs a statement confirming that the product complies with all EU directives.

5. Affixing the CE mark

The CE mark must be marked in a prominent position on the product or packaging. The mark must be clear and indelible.

II. Main standards involved

The specific standards that electronic appliances must comply with for CE certification vary according to different directives. Common standards include:

1. LVD directive related:

EN 60335-1 (General safety standard for household appliances);

EN 60950-1 (Safety standard for information technology equipment).

2. EMC directive related:

EN 55032 (Electromagnetic compatibility emission standard);

EN 61000 series (Anti-interference capability standard).

Other standards: such as EN 50564 (Energy consumption standard).

III. Core test items to be carried out

1. Electrical safety test

Withstand voltage test, ground continuity test, leakage current detection.

2. Electromagnetic compatibility test

Radiated emission test, conducted emission test, electrostatic discharge (ESD) immunity test.

3. Material and environmental test

Flame retardancy test, high temperature resistance test, mechanical strength test.

IV. CE mark affixing specifications

1. Size requirements:

The mark height is ≥5mm, and the original proportion must be maintained when scaling.

2. Position requirements:

It should be affixed to the product body first. If there is insufficient space, it can be marked on the packaging or instructions.

3. Format requirements:

The letters "C" and "E" must be arranged in equal proportions and must not be deformed.

V. Notes

1. High-risk products (such as medical devices) must be certified by a notified body and cannot be self-declared.

2. Technical documents must be updated regularly to respond to changes in EU regulations.

3. The CE mark must not be confused or blocked with other certification marks.
