What are European electromagnetic requirements?
The European Commission has issued The EMC Directive, 89/336/EEC, which requires that end user equipment meets prescribed electromagnetic compatibility requirements. National government implement the directive by reference to harmonized standards. In the majority of cases, conformity to the EMC directive can be demonstrated by compliance with EN50081 for emissions and EN50082 for susceptibility. These are known as the "Generic EMC Standards". These standards, in turn, refer to further standards, as follow:
EN50082 (susceptibility)
- IEC801-2
- IEC801-3
- IEC801-4
- IEC801-5
EN50081 (emissions)
- EN55022 Line conducted and radiated RF emission
- EN60555-2 Harmonic line currents (household/ domestic equipment only)
