Conducting emission exceeding test is to test whether the equipment under test (EUT) passes the limit of electromagnetic disturbance under the standard frequency band according to the relevant national / industry regulations. Conducting emission test, also known as disturbance voltage test, involves all products as long as they have power lines, including many DC power supply products. In addition, there are also requirement regarding the signal / control lines conducting emission in many standards, usually expressed by the limit of disturbance voltage or disturbance current (There exist some relationships of conversion between them). The insertion loss test (expressed directly by dB) in lamps and lanterns also falls into the category of conduction test.
