IEC 61000-4-20
IEC 61000-4-20: Electromagnetic Compatibility (EMC) - Part 4-20: Testing and Measurement Techniques - Emission and Immunity Testing in Transverse Electromagnetic (TEM) Waveguides The purpose of this standard is to describe TEM waveguide characteristics, including typical frequency ranges and EUT-size limitations; TEM waveguide validation methods for EMC tests; the EUT (i.e. EUT cabinet and cabling) definition; test set-ups, procedures, and requirements for radiated emission testing in TEM waveguides and test set-ups, procedures, and requirements for radiated immunity testing in TEM waveguides.
