My experience has been that your approval is not limited to the rack that you used during the testing. The only situation I could think of where this might not be the case is if you had originally failed and needed a rack with specific response criteria in order to pass.
Comments?? -----Original Message----- From: Scott Lemon [mailto:sle...@caspiannetworks.com] Sent: Wednesday, February 13, 2002 10:19 AM To: Nebs (E-mail) Subject: GR-63 Seismic Greetings Nebs group, I am interested in the general consensus with respect to one aspect of seismic testing of rack mounted equipment.... If a shelf-based system, which is designed to be installed in any seismic approved rack assembly (e.g. 19"), is seismic tested in a particular rack (e.g. Newton), is the performance normally extrapolated to be representative of installation in any generally "seismic approved" 19" rack (e.g. Hendry, tested by rack manuf with dummy loads, etc.)?? In other words, is GR-63 seismic compliance for the shelf system linked only to the rack in which it was tested, or will any generally tested GR-63 "seismic approved" rack suffice? Any and all opinions welcome. Thanks, Scott -- Regards, Scott Lemon CASPIAN NETWORKS sle...@caspiannetworks.com www.caspiannetworks.com
