Electromagnetic Compatibility (EMC)
Definition of Electromagnetic Compatibility, known as “EMC”
Electromagnetic Compatibility (EMC) is the ability of an electrical or electronic device to operate correctly in its electromagnetic environment without causing or suffering from electromagnetic interference.
Notably, within the framework of applying EMC Directive 2014/30/EU or RED Directive 2014/53/EU, it is mandatory to declare compliance with their requirements before its placing on the market .
EMC activities address two specific objectives:
- the ability of equipment to function correctly in an electromagnetically disturbed environment;
- that the level of electromagnetic pollution generated by equipment does not reach values that could compromise the proper functioning of other devices located in its vicinity.
What is Electromagnetic Pollution?
Electromagnetic pollution refers to the emission of uncontrolled, unwanted, or undesirable electromagnetic radiation affecting the electromagnetic compatibility of electrical devices. It can violate regulations and standards, and potentially pose public health or ecological problems. This pollution results from exposure to electromagnetic fields originating from intentional emitters (such as TV, radio, mobile telephony transmitters) and unintentional emitters (like clock frequencies, power switching, etc.)
The level of this pollution primarily depends on the power, frequency, and even the modulation type of the received electromagnetic field, as well as the duration of exposure.
Electromagnetic pollution is a growing concern, especially with the advent of technologies such as the Internet of Things and 5G, which introduce multiple radiofrequency emitters into the environment.
Which Equipment is Affected by Electromagnetic Compatibility?
Products concerned by EMC are an integral part of our daily lives. These products can take the form of a vehicle, a vacuum cleaner, or even an internet box. As soon as a device consists of electronic components, it is subject to electromagnetic compatibility requirements.
This dimension becomes even more critical when controlling safety/security equipment designed to prevent risks.
Advantages of CNPP Laboratories
For nearly 30 years, the EMC and radio testing laboratory has distinguished itself by its exceptional technical expertise in conducting tests aimed at evaluating your product's susceptibility to a multitude of electromagnetic disturbances and at measuring their level of emission. Our activities are regularly assessed by the French accreditation committee "COFRAC" (scope available on www.cofrac.fr).
