IEC 61000-4-20
The EN/IEC 61000-4-20 standard describes how Immunity and Emission measurements are performed in a transverse electromagnetic (TEM) waveguides.
The exact title of this standard is: "IEC 61000-4-20: Electromagnetic compatibility (EMC) - Part 4-20: Testing and measurement techniques - Emission and immunity testing in transverse electromagnetic (TEM) waveguides"
This review is based on the Edition 2.0 2010-08 version.
Some random remarks and notes:
- It is advised to not use EUT that are larger than 1/3 of the height of the usable height of the TEM.
- For the Immunity testing, the standard describes that the Uniform Field Area in the TEM should be verified, using the procedures similar to as described in the EN 61000-4-3.
