Given that is is a magnetic field immunity test, I would guess that any ferrous metal that would affect/distort the magnetic field would not be desired. I would be willing to bet that the standards people had that in mind, and meant that any magnetic metal should not be used. Also note that the GRP for a table-top test is not longer required. I asked the question a while back about why the GRP was specified in the first place, and why it was taken out in the latest release of the standard, and never did get an informed answer. I may have gotten a rather colorful tongue-in-cheek response from Mr. Woodgate, however. :-) Bob R.

Can anyone on the list that partook please give me insight? Thank you!

It's just not clear. Perhaps someone who was involved in writing the standard can help. -- OOO - Own Opinions Only.
