What are the CE EMC standards

What is EMC?

EMC (Electromagnetic Compatibility) refers to the ability of electrical equipment to function normally in its electromagnetic environment. It encompasses two core requirements: the equipment must not generate excessive electromagnetic interference, and it must simultaneously possess the ability to resist external interference.

What is the EMC Directive?

The EMC Directive 2014/30/EU is the core regulation of the EU ce marking system. It came into effect on April 20, 2016, replacing the old directive 2004/108/EC. This directive applies to all electrical and electronic equipment sold on the EU market, with two core objectives:

• Emission limits: The electromagnetic interference generated by the equipment must not exceed permissible levels.

• Immunity requirements: The equipment must have sufficient anti-interference capability in its intended electromagnetic environment.

Difference between EMC and LVD

The EMC Directive focuses on electromagnetic compatibility, while the LVD Directive (2014/35/EU) focuses on electrical safety. Both usually need to be met simultaneously to affix the CE mark.

Standards by Product Category

Multimedia/Information Technology Equipment

Key Note: EN 55032 only covers emission requirements and must be used in conjunction with EN 55035 to constitute a complete EMC assessment.

Industrial Environment Equipment

Residential/Commercial/Light-Industrial Environments

Measurement, Control and Laboratory Equipment

General Basic Testing Standards

CE emc compliance Process

1. Determine the product category and applicable standards

2. Conduct an EMC risk assessment

3. Product design and implementation of EMC measures

4. Internal pre-testing (Optional)

5. Third-party laboratory JJR LAB provides testing

6. Prepare technical documentation

7. Sign the EU Declaration of Conformity (DoC)

8. Affix the CE mark

9. Place on the market

10. Retain documents for 10 years and monitor continuously

Technical Documentation Requirements

Technical documentation must include:

• Product description and specifications

• EMC risk assessment report

• Test reports (conducted according to harmonized standards)

• Declaration of Conformity (DoC)

• User manual and installation instructions

• Design drawings and circuit diagrams

Common Compliance Errors

• Using expired or withdrawn harmonized standards

• Testing only for emissions and not for immunity

• Missing the RED directive for wireless products

• Incomplete technical documentation

• Improper use of the CE mark

• Abuse of family series reports

Relationship with Other Directives

For radio equipment, the RED directive already covers EMC requirements, so the EMC directive does not need to be applied separately.

Frequently Asked Questions (FAQ)

Do all electrical products need emc testing?

A: Yes, almost all electrical and electronic equipment is subject to the EMC directive, unless there are specific exemptions.

Does EMC testing require the involvement of a Notified Body?

A: Generally, no. When fully applying harmonized standards, manufacturers can self-declare conformity.

Are test reports using old versions of standards still valid?

A: You must use the version of the harmonized standard currently listed in the Official Journal of the European Union. Expired standards cannot provide a presumption of conformity.

If a product has passed FCC certification, does it still need ce emc?

A: Yes. The US FCC and ce emc test methods and limits are different and cannot substitute for each other.

How long does EMC testing usually take?

A: Depending on the complexity of the product, it usually takes 2-4 weeks. Pre-testing can help discover problems early and shorten the formal testing cycle.
