The Electromagnetic Compatibility Directive (EMC)

The Electromagnetic Compatibility Directive (EMC)

Directive 2014/30 / EU of the European Parliament and the Council - 26 February 2014 - harmonizing the legislation of Member States in terms of electromagnetic compatibility of devices that you can place on the market. The EMC Directive arises as a regulator text in the context of the safety standards - referring to IEC / EN ISO technical rules to which the electrical products must meet - and thus ensuring that the equipment approved in one EU member state to comply all other EU countries. These products, They will be liable to be marked with the CE Marking, and to be explicit as compliant through the CE declaration of conformity.

This Directive is part of the legislative framework for the free movement and marketing of products in the European community. Its ultimate aim is to avoid the risks related to a product or to a phenomenon, thus defending the common interest of European citizens and companies.

The English name for this directive: Electromagnetic Compatibility (EMC) Directive;

Its abbreviation is: EMC;

Its code is: 2014/30/I;

Previous directives on this subject, Today they are no longer in force: 2004/108/EC, 89/336/CEE.

E 'useful to know the references of the directives because they often are in the products or components documentation, but also in the European laws and regulations if they have not recently been updated.

Field of application: EMC Directive 2014/30 / EU concerns every finished device – or combination of finished devices – made available in the market as a single functional unit, intended for the final user and capable of generating electromagnetic disturbance, or whose operation can be affected by such disturbances. Moreover, Directive involves the particular combinations of several types of apparatus and possibly other devices, which are assembled, installed and intended to be used permanently at a predefined location.

essential requirements: affected products from the scope of the Directive, to be put on the European market, must comply with the following essential requirements.

  • The electromagnetic disturbances produced must not exceed the level above which radio and telecommunications equipment or other equipment can not operate normally;
  • The level of immunity to electromagnetic disturbances predictable based on the use to which they are intended for permitting the normal operation, without unacceptable deterioration.

They are intended as "Background" the reasons that led to the writing of that directive.

Field of application

The scope defines the categories of products or phenomena covered by Directive. Often a general criterion is expressed accompanied by explicit lists of products / phenomena that are subject to the Directive and product / phenomena that are excluded from the Directive in order to clarify the specific situations.

definitions

In the section "Definitions" means including all those specific explanations of key terms in the Directive, useful to fully understand the scope.

essential requirements

The essential requirements are the requirements which the product must meet in order to be placed on the market. Often the essential requirements are placed in Annex I to Directive.

Obligations of the manufacturer

The manufacturer (or his authorized representative in the European Community) is the main person responsible for placing a product on the market. This chapter describes the requirements and procedures that they must follow, referring to the Annexes to Directive for explanations and more detailed regulations.

Obligations of the other economic operators

Distributors and retailers are also responsible and liable if they trade items that do not comply with European directives. They must verify that the manufacturer did run the electrical safety testing, that the product is provided with the EC declaration of conformity and carry the CE mark.

Any importer must ensure that the procedures for the verification of conformity of the product have been performed, must check for the CE marking and ensure that the technical documentation of the product is available to national competent authorities.

Free movement

Member States must presume that products bearing the CE marking comply with all the provisions of the applicable directives providing for the affixing. They can not therefore be prohibited, restrict or prevent the placing on the market and putting into service in their territory of products bearing the CE marking, unless the provisions relating to CE marking have not been applied improperly.

Presumption of conformity and harmonized standards

At the directives of our interest it is associated with a list of harmonized standards that is published in the European Official Journal. The harmonized standards greatly facilitate the verification of compliance of a product with the requirements of Directive. In these standards is described in detail how the tests should be performed or other kinds of assessment needed to verify that a product complies.

If a product is available the harmonized standards to cover all the requirements of the Directive - if these standards are applied comprehensively and the product passes all tests provided by the same rules – then it can be assumed that the product complies with the requirements of that Directive. In the absence of harmonized standards adequate to the product path it is more complicated and expensive.

Equipping an EMC laboratory suitable to perform the tests required by the Harmonized Standards thing is rather onerous. For this reason, manufacturers will often rely on external testing laboratories.

notified bodies

In Europe it is the body that can make an assessment of compliance by acting as a third party or whether the one made by the manufacturer and its trusted laboratories is correct. In most cases, however, the use of a notified body is not provided or not required.

CE Marking

The products comply with all the provisions of the applicable directives providing for the CE marking must convey it. Such marking is, in particular, an indication that the products comply with the essential requirements of all applicable directives and that they were subjected to a conformity assessment procedure provided for by the Directives. Member States are also required to take the necessary measures to protect the CE marking.
