Electromagnetic Compatibility

The Directive: EMC 2004/108/EC

in Electromagnetic Compatibility

EMC Directive 2004/108/EC (Electromagnetic Compatibility Directive) of the European Parliament and of the Council was published on December 31, 2004 in the Official Journal of the European Union, L 390/24, and replaced Directive 89/336/EEC on July 20, 2007.

2004/108/EC Directive regulates the electromagnetic compatibility (EMC) of both apparatus and fixed installations.

The directive applies to most electrical and electronic apparatuses, that is, finished products and systems that include electrical and electronic equipment.

    • The main objective of the EMC Directive is thus to regulate the compatibility of equipment regarding EMC. In order to achieve this objective, provisions have been put in place so that: equipment (apparatus and fixed installations) need to comply with the requirements of the EMC Directive when it is placed on the market and/or taken into service.
    • The application of good engineering practice is required for fixed installations, with the possibility for the competent authorities of Member States to impose measures if non-compliance is established.

The EMC Directive 2004/108/EC applies to a vast range of equipment encompassing electrical
and electronic appliances, systems and installations.

The Directive 2004/108/EC applies to:

• Electrical and electronic appliances, systems, and installations including electrical and electronic appliances
• Fixed installations
• Devices and subassemblies intended to be included in an apparatus by the final user and mobile installations

It excludes:

• Equipment covered by the radio and telecommunications terminal
• Equipment Directive 1999/5/EC
• Radio equipment used by radio amateurs
• Equipment where EMC is covered by other specific directives, such as marine equipment
if covered by Directive 96/98/EC or active implantable medical devices under the 90/385/EEC Directive
• Inherently benign equipment

This directive shall not apply to:

• Equipment when covered under the radio equipment and telecommunication terminal directive R&TTE, nor aeronautical products, parts and apparatus, nor radio equipment used by amateur radio operators
• Equipment incapable of generating or contributing to electromagnetic emissions
and/or operates without unacceptable degradation in the presence of electromagnetic disturbance as normally seen in its intended use


in Electromagnetic Compatibility

When complying with this directive, products need to comply with the protection requirements according to Annex I of the EMC Directive. Compliance with these protection requirements is demonstrated by applying the conformity assessment procedure detailed in Annex II or Annex III of the directive. Technical documentation must be prepared to demonstrate evidence of compliance with the protection requirements. EMC assessment of products must be performed in order to demonstrate that it meets the protection requirements. All measures necessary must be taken to show that electrical equipment is manufactured in accordance with the technical documentation. EC Declaration of Conformity must be completed and affix the CE marking. You may opt on a voluntary basis to involve a Notified Body during the conformity assessment procedure to review your Technical Documentation.

Protection requirements for all equipment

Equipment shall be so designed and manufactured as to ensure that:
• The electromagnetic disturbance generated does not exceed the level above which radio and telecommunications equipment or other equipment cannot operate as intended
• It has a level of immunity to the electromagnetic disturbance to be expected in its intended use which allows it to operate without unacceptable degradation of its intended use

Specific requirements for fixed installations

Fixed installations shall be installed applying good engineering practices and respecting the information on the intended use of its components.

For non-EU manufacturers: Appoint a European Authorized Representative established within the European Community.


The directive portrays European Law enforced within the European Economic Area (EEA); non-compliance with the directive’s requirements will result in the removal of the apparatus from the market and the revoking of the CE marking affixed on the apparatus.
