Electronic, for almost half century, plays a crucial aspect in the product design of daily use, industrial as well as domestic.
Electric and electronic systems, based on electrical signal to carry out easy or complex tasks and operations, are not infallible but, as for living being, susceptible to external stimulus.
Reliability of electrical and electronic systems is doubtless related to the ambient conditions: temperature, height, humidity, pression are all parameters capable to affect such devices.
An additional, very important, parameter is the electromagnetic compatibility, since it measures how the system can interfere with another one.
But what does it mean exactly?
Electromagnetic compatibility (or EMC) means the capability of a device to be immune from the electromagnetic perturbations coming from the environment.
And what does it stand for “electromagnetic perturbation”?
In a broader context all electromagnetic waves are included as possible perturbation source, such as radio-waves, micro-waves, infrared, visible and UV radiation, X-rays and g-rays.
Every type of wave can lead to a malfunction when interferes with an electric and/or electronic system: the higher the energy, the more severe the interference.
X- and g-rays can be excluded from this context since they are available only in specific applications and conditions. The large majority of devices are exposed to weaker waves as radio waves, microwaves, infrared and visible light.
The Directive 2014/30/EU on electromagnetic compatibility regulates this aspect imposing emission and immunity constraints to all the devices placed on the market that can emit and/or being disturbed by electromagnetic radiation.
This Directive is rather broad and cover devices used in industrial environment and civil as well (domestic).
Since these objects can be assembled to realise a more complex assembly, it can happen that the new device would emit a new type of electromagnetic wave and/or be perturbed from a signal that was inefficient before.
For this reason is a good practice to verify the applicability and the compliance to EMC Directive. To proof the latter point EMC tests specifically designed for the final installation environment of the device are necessary.
If a situation like this is familiar and you face frequently similar cases, we, as Advolo, can offer you a team of experts in the sector of EMC certification, happy to support you from the project design to the compliance with relevant standard, until the legal compliance to the applicable Directives. Be careful, for large scale machinery and fixed installation, the EMC tests can be carried out as well on site.
