About
EMC
Ensuring electrical equipment is safe and does not interfere with the
normal operation of other equipment is the basis for Electromagnetic Compatibility
(EMC) regulation. The most common forms of EMC are known as electromagnetic
emissions and electromagnetic immunity.
Around the world,
many countries have set regulations and laws that govern the use of EMC.
For example, in Europe the Electromagnetic
Compatibility Directive 2004/108/EC sets the requirements for the control
of immunity and emissions. In the United States, the FCC governs the requirements
for the control of immunity and emissions.
Electromagnetic
Emissions
Electromagnetic Emissions relate to radio frequency waves that are emitted
from an electronic device during normal operation. These electromagnetic
waves can interfere with the normal operation of other electronic equipment.
Each product has specific frequency ranges allowed to transmit these emissions
within. The frequency ranges have been determined by the type of product
and by the regulatory authorities of countries across the world, such
as the FCC and European Norms.
Electromagnetic Immunity
Electromagnetic
Immunity refers to a product's ability to withstand a specified level
of external electromagnetic interference. With the proliferation of electronic
devices, there are an increasing number of standards covering a range
of product immunity issues including Electrostatic Discharge (ESD), Radiated
Electromagnetic Field Immunity, Electrical Transient/Burst Immunity, Surge
Immunity, and Immunity to Conducted Disturbances. TÜV Product Service
can provide testing and consultation for all your immunity needs.
