Hello Enci, Even though EMC compliance is regulated around the world the majority of times that people are found to be non-compliant is from complaints. In most cases it is competitors blowing the whistle on each other. However, as a product safety professional I am usually not concerned with EMC non-compliance unless it poses a potential safety hazard. The severity of non-compliance as to its affect on the well being of the public and environment will always be weighed on its significance to cause harm. Chances are, if a product is not compliant and is not affecting the airways or the power company, it will go unnoticed.
