OOPS- Good eye Valerie..............But I should have used the term "Maximum Operating Temperature" regarding the 130C UL rating. I just checked my copy of UL 796 & Material Table I in our UL Followup Procedure. Both list "MOT" values. Sorry about my error. Mark PS- Tonight I'll look into UL 796 further. I'll bet the complete term is listed somewhere as "MCOT". -----Original Message----- From: Valerie St.Cyr [SMTP:[log in to unmask]] Sent: Wednesday, May 14, 2003 3:30 PM To: [log in to unmask] Subject: Re: [TN] Hot Boards! 2 terms COT and MOT (Continuous; Maximum) are they the same? If not, can someone point to the definition. I don't have a copy (anymore) of UL but they own the COT definition ... who owns the MOT definiton?
