What would be the use of immortality to a person who cannot use well a half an hour? - Ralph Waldo Emerson
Product Consulting, Electromagnetic compatibility Directive
  1. What is Electromagnetic compatibility Directive?
    The EMC Directive differs from most other directives in that its primary requirement is protection of the electromagnetic spectrum rather then safety of the equipment.

    The vast majority of electrical products must comply, whether battery or mains powered. Exceptions include but are not limited to components and sub assemblies with no intrinsic function, products already covered by other directives, (medical, military, automotive, some agricultural, transmitting and communications equipment).

    The Directive requires that products must not emit unwanted electromagnetic pollution (interference) and must be immune to a normal level of interference. Compliance with these requirements is usually demonstrated by testing to harmonized standards but testing is not mandatory and a manufacturer may choose provide a technical assessment for compliance as an alternative.

    In the UK the Directive is enforced by the Trading Standards Service and Of com. Penalties for non-compliance can include three months imprisonment and a £5000 fine but generally involves a recall and replacement of the affected product.

  2. Why Certification for Electromagnetic compatibility ?

  3. Who Needs to Comply with the EMC Directive?
  4. The EMC Directive is one of the 'New Approach' Directives and applies across all 27 member states of the European Union (EU). The Directive applies to all electronic or electrical products liable to cause or be disturbed by electromagnetic interference (EMI). As a result a large number of manufacturers in the electronics or electrical industries need to ensure that their products are compliant with the requirements of the Directive and be able to demonstrate that this is the case in order to affix a valid CE Marking

  5. What are the Benefit of EMC Directive ?
  6. Compliance with the European Union’s EMC Directive leads to increasingly robust products, improvements in quality and increased customer satisfaction. For example, ESD (electrostatic discharge) Immunity Testing quickly reveals any latent vulnerability a product might have to such standards and promotes corrective measures that render the product immune to such real world occurrences. The result is improved customer satisfaction realized from reliable, solid products that provide years of trouble free service

  7. What is the purpose of EMC Directive ?
  8. The Electromagnetic Compatibility (EMC) Directive 2004/108/EC is one a series of measures introduced under Article 100a of the Treaty of Rome. Article 100a directives all have the primary objective of creating a single European market in goods and services with the objective of providing producers and consumers with the benefits of economies of scale that this offers. The effect of the Directive has been to introduce identical requirements for the EMC performance of electrical apparatus in every country within the European Economic Area (EEA). These requirements are intended to ensure that electrical apparatus will function without causing or being affected by undue interference to or from other apparatus. As the number and type of electronic devices in homes and businesses across Europe increases, the Directive is an important measure to ensure that equipment will continue to function as its makers intend and purchasers have a right to expect

  9. What is CE marking Procedures of EMC ?
  10. In order to indicate that a product complies with the essential requirements of the EMC-directive, a correlation can be made with the technical standards. There are two separate methods for the selection of standards and criteria that can be used to demonstrate compliance with the directive:

    • Compliance with the harmonized European EMC Standards (EN standards);
    • Compliance with specified requirements, if there are no standards for the product or if the standards cannot be fully followed.
    • EN standards:
      In principle Module A applies: the manufacturer verifies compliance of the product-design with the harmonized EN-standards and provides evidence of this compliance in the "Technical

    • No EN standards, or incomplete use :
      In principle Module Aa applies: the manufacturer compiles a "Technical Construction File" for the product. This file must contain the following information:

      A list of the standards that are in fact employed or those that are partially employed;

      A list of the measures taken in order to comply with the EMC requirements for which no standards are employed;

      Technical report or certificate by an authorized organization ("Competent Body" in the scope of the EMC-directive), in which it is stated that as a result of the measures taken there is compliance with the essential safety requirements.

      For products with the CE marking a "Declaration of Conformity" shall be made

  11. Which product can go for electromagnetic compatibility ?
