EMC TESTING

The EMC Directive concerns electromagnetic compatibility - to ensure that products can function without interfering with (emission) or being susceptible to interference from (immunity) other products.

For what Products?

The Directive applies to almost all electrical equipment regardless of whether it is battery driven, uses an external electricity supply, or operates from mains or high voltage. It also applies to equipment, machinery and installations which contain electrical or electronic components.
