The EMC Directive 2014/30/EU came into force on the 20th of April 2016 and is aligned to the New Legislative Framework. The Directive ensures that all electrical and electronic equipment, placed on the EU market, comply with the allowed adequate level of electromagnetic compatibility. In this regard, the electrical products shall not generate or be affected by any electromagnetic disturbance. The EMC’s purpose is to keep all side effects, appearing when electrical devices are interconnected or close to each other, under control. For instance, possible interference between TV sets, radios, electrical power lines and others. Moreover, the Directive limits electromagnetic emissions from electrical equipment so that such equipment doesn’t disturb the activity of other equipment, such as radio or telecommunication, when used as intended.
There are two primary objectives of the EMC Directive:
The new EMC Directive 2014/30/EU has the same scope as the old one from 2004/108/EC and covers a vast range of equipment, encompassing electrical and electronic appliances, systems, and installations, defined as apparatus or fixed installations. In this regard, it is of importance to specify what apparatus and fixed installations mean.
For instance, an apparatus can be:
“Fixed installations” refers to a particular combination of several types of apparatus and, where applicable, other devices, which are assembled, installed and intended to be used permanently at a predefined location. More illustrative examples of fixed installations could be, as follows:
Within the scope of the Directive are not included electromagnetic fields and their effects, as well as radio systems and aeronautical products, parts, and appliances. Other examples of equipment excluded from the EMC Directive’s scope are:
The electromagnetic compatibility of products can be tested w.r.t. radiated interference and their resistance to interference. Most common EMC tests are, as follows:
I – Measuring emissions in terms of:
II – Tests for resistance against electromagnetic influences:
