It sounds as if they are saying other non-magnetic metals, such as brass. Ken Javor Phone: (256) 650-5261
From: Derek Walton <lfresea...@aol.com> Date: Tue, 5 Jun 2012 11:26:32 -0400 (EDT) To: <emc-p...@ieee.org> Subject: EN61000-4-8 Folks, I have a question about Section 7.2 of this document. Specifically, what metal is permissible for use as a GRP. The wording of the standard is: "The ground plane shall be a non-magnet metal sheet ( copper or aluminum ) of 0.25 mm minimum thickness; other metals may be used but in this case they shall have at least 0.65 mm minimum thickness." So, does this mean that magnetic metals can be used if they are over 0.65 mm? Presumably then the concern is saturation of very thin sheets?
