I don't know either I am assuming that they are just trying to
standardize the test "cell" if you will. You're right the field of interest
is inside the loop and the external lobs shouldn't be a problem whether or
not the fringe with a ground plane or not, even if they did I think the
ability would exist to increase the field strength for the EUT to
compensate.
I suppose there is something obviously wrong with my assumption but
that wouldn't be the first time.

Subject: RE: 61000-4-8 Ground Plane
61000-4-8 is an immunity test. It totally immerses the EUT in a magnetic
field
at 50 Hz. I still don't know what the ground plane is for.
