Greeting colleagues,
In IEC 61000-4-9, Section 7.3 it states the following - "Table-top EUT's shall be placed on a non-conductive table." Up until now, I have always thought that "non-conductive" had meant no metals, such as iron, steel, aluminum, copper, etc. In that meaning, the table would then be made of wood, foam, etc. However, I have been advised that for this particular case of impulse magnetic field immunity test, that "non-conductive" is referring to material that should not be magnetic conductive, such as aluminum or copper. Iron and steel would not be used, as these are considered magnetic conductive. And therefore, an aluminum or copper sheet would be placed on the table under the EUT. The standard does not provide guidance as to the use of "non-conductive" that would mean in essence, "should not be magnetic conductive". Any guidance and insight would be most helpful.
