Types of product testing under the EMC Directive

The electromagnetic compatibility of products can be tested in regards to radiated interference and their resistance to interference. Most common EMC tests are, as follows:

a) Measuring emissions in terms of:

• interference induced by the applied voltage
• radio interference emitted
• interference power
• harmonic currents
• flicker.

b) Tests for resistance against electromagnetic influences:

• Electrostatic discharge
• Electromagnetic fields
• Speed pulses
• Shockwave
• Conducted electromagnetic interference
• Power frequency magnetic field
• Interruption of and changes to the power supply.
