The EMC Directive - officially named Electromagnetic Compatibility (EMC) Directive 2014/30/EU of the European Parliament and of the Council – ensures that electrical and electronic equipment does not generate electromagnetic disturbance, or is not affected by electromagnetic disturbance.
The legislation sets out limits for electromagnetic emissions from equipment, so that mediums such as telecommunication, radio, and other equipment are not disturbed. It also concerns the immunity of equipment to interference, aiming to protect this equipment from disturbance by radio emissions when it is in use.
The full version of the EMC Directive – which you can download here – runs to 28 pages. We have created this guide to highlight some of its most important elements.
The EMC Directive is focused on regulating the compatibility of equipment in relation to electromagnetic fields. Its main objectives are to ensure that:
The EMC Directive covers the majority of finished mains or battery-powered electrical products. Exceptions to the guide include sub assemblies and components without an intrinsic function, (i.e. they are only of use when combined with other components). There are also some exceptions which are already covered in other directives, including; medical devices; communications equipment; road vehicles; agricultural vehicles; and military equipment.
In the UK, the EMC Directive is officially implemented by The Electromagnetic Compatibility Regulations 2006. These regulations are enforced by the Trading Standards and Ofcom. The Health and Safety Executive can take part in investigations into non-compliant products, as can the Department of Trade and Industry’s radiocommunication agency, and the British Approvals Board for Telecommunications.
Businesses which are found to be supplying non-compliant equipment face a maximum penalty of three months imprisonment, or a £5,000 fine. Typically manufacturers are asked to replace or recall apparatus which is found to be non-compliant. The sale of apparatus which is found to be non-compliant can be suspended or banned by the relevant authority.
Assessments for EMC Directive conformity
There are five classes of assessments which have the purpose of testing for EMC Directive conformity:
There are two conventional routes to confirming compliance with the EMC Directive:
1. Standards Route
The electrical products which many manufacturers produce are of no concern in relation to the EMC Directive, and in these cases organisations are able required to take a logical approach to the requirements, which is known as the Standards Route. This way of complying with the EMC Directive allows the manufacturer themselves to compare the performance of their equipment with the harmonised standards set out in the Directive. If they are sure that the standards have been met, manufacturers can make a Declaration of Conformity. In these cases testing can sometimes be required, but is not mandatory.
2. Technical Construction File
With electrical products for which there are no harmonised standards, or when testing must be conducted outside the confines of the manufacturer’s site in order to demonstrate compliance, the manufacturer is required to put together a Technical Construction File. The results of these assessments, along with the other information in the Technical Construction File, are then audited in order to assure that the electrical products comply with the EMC Directive.
A Technical Construction File typically contains information such as; a general description of the equipment; design and drawings of the equipment; proof (if any) of compliance with harmonised standards; in the absence of standards, a description and proof of how the requirements of the Directive have been met; details on assessments made; a Declaration of Conformity.
CE marking provides manufacturers with a way to make a visible declaration that electrical products comply with the EMC Directive. CE marking is a required form of EMC Directive compliance which accompanies a Declaration of Conformity. It also confirms that electrical products have free circulation within the European Economic Area.
Manufacturers which operate a site which uses high voltage applications need to consider EMF safety. Read about IES’s EMF testing service here.
