ELECTROMAGNETIC COMPATIBILITY

The electromagnetic force is the one responsible for practically all the phenomena one encounters in daily life above the nuclear scale, with the exception of gravity. That is why, the Electromagnetic Compatibility (EMC) Directive 2014/30/EU regulates the electromagnetic compatibility of equipment and ensures the free movement of apparatus and creates an acceptable electromagnetic environment in the domestic market requesting a harmonised and acceptable level of protection.

The electromagnetic force is one of the four known fundamental forces. The other fundamental forces are: the strong nuclear force, which binds quarks to form nucleons, and binds nucleons to form nuclei the weak nuclear force, which causes certain forms of radioactive decay and the gravitational force. All other forces (i.e. frictional force) can, in the end, be explained by the electromagnetic force on particles and the momentum created by their movement.

The electromagnetic force is the one responsible for practically all the phenomena one encounters in daily life above the nuclear scale, with the exception of gravity. That is why, the Electromagnetic Compatibility (EMC) Directive 2014/30/EU regulates the electromagnetic compatibility of equipment and ensures the free movement of apparatus and creates an acceptable electromagnetic environment in the domestic market requesting a harmonised and acceptable level of protection. The equipment must be designed and manufactured in the latest technology providing the following conditions:

The electromagnetic disturbance generated must not exceed the level above which radio and telecommunications equipment or other equipment cannot operate as intended.

The equipment must have 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.

A fixed installation must be installed applying good engineering practices and respecting the information on the intended use of its components, with a view to meeting the protection requirements. Those good engineering practices must be documented and the documentation must be held by the person(s) responsible at the disposal of the relevant national authorities for inspection purposes for as long as the fixed installation is in operation.

The technical documentation must enable the conformity assessment of the apparatus with the essential requirements. The technical documentation must cover the design and manufacture of the apparatus, and particularly contain the following:

  • A general description of the apparatus,
  • Evidence of compliance with the harmonised standards, if any, applied in full or in part,
  • Where the manufacturer has not applied harmonised standards, or has applied them only in part, a description and explanation of the steps taken to meet the essential requirements of the Directive, including a description of the electromagnetic compatibility assessment, results of design calculations made, examinations carried out, test reports, etc.
  • A statement from the notified body delivered upon the manufacturer’s request.
