The Electromagnetic Compatibility Directive (2014/30/EU)—commonly known as the EMC Directive—is a key regulation that ensures electronic and electrical equipment functions properly without causing or being affected by electromagnetic interference (EMI). It applies to a wide range of products and is essential for manufacturers, importers, and distributors placing such products on the EU market.
What is the EMC Directive?
The EMC Directive aims to guarantee that equipment will operate as intended in its electromagnetic environment, and will not produce disturbances that could interfere with the operation of other devices. It became fully applicable on 20 April 2016, replacing Directive 2004/108/EC.
The directive covers almost all electrical and electronic appliances and systems, from consumer electronics to industrial machinery, unless specifically excluded (e.g., radio equipment covered by RED or medical devices covered by MDR).
Scope of the EMC Directive
The directive applies to:
- Electrical and electronic appliances
- Fixed installations
- Systems and assemblies
- Machines with embedded electronic controls
It does not apply to:
- Equipment covered by more specific EU directives (e.g. RED, LVD, medical devices)
- Radio amateur equipment not commercially available
- Products inherently immune to EMC issues
Essential Requirements under EMC
The EMC Directive sets out two key requirements:
- Emissions: Equipment must not emit electromagnetic disturbances that exceed levels at which other equipment cannot operate as intended.
- Immunity: Equipment must have adequate immunity to electromagnetic disturbances so that it operates without unacceptable degradation.
These requirements apply both to stand-alone devices and installations. For fixed installations, there are additional provisions around documentation and good engineering practice.
Conformity Assessment and CE Marking
Before placing a product on the EU market, manufacturers must:
- Perform an EMC assessment based on harmonised standards
- Prepare and keep technical documentation
- Draft and sign an EU Declaration of Conformity
- Affix the CE marking
Unlike some other directives, the EMC Directive usually allows for self-certification by the manufacturer (no involvement of a notified body), unless specific standards are not followed or there are particular risks.
Harmonised Standards and Presumption of Conformity
Applying relevant harmonised European standards (EN standards) provides a presumption of conformity with the EMC Directive. These standards define test methods, limits, and procedures that help ensure compliance.
Some widely used EMC standards include:
- EN 55032: Multimedia equipment
- EN 61000 series: Industrial environments and immunity testing
- EN 55035: Information technology equipment
Responsibilities of Economic Operators
All economic operators involved in the supply chain—manufacturers, importers, and distributors—must ensure that the product complies with the EMC Directive:
- The manufacturer must perform testing and produce technical documentation.
- Importers and distributors must verify that the appropriate procedures have been carried out and that the CE mark and documentation are in place.
