I hope that someone in this group can help me find this information. I have
been asked to find an outside source or company that can do MTBF reports.
Any information would be appreciated.
Thanks,

Also try Littelfuse. They now own the Harris/GE varist

Confused and missing something pretty basic here, I think.
As I look at the diagrams in annex NAB for UL 1950 or UL60950 I am
pretty confused.

I do not have a copy of EN60825-1. Can any body tell me what the output

Good question. This does appear to be a problem. It appears that the dates
for the Basic standards, when they are first published, are set by their
adoption in the Generic, Family and Product standards. Therefore the DOP and
DOW of those higher level standards govern when we must use the Basic

Richard, perhaps you or someone can help me with basic standards. It is my
understanding that DOWs are set by the European Commission (and not CENELEC) and
the DOWs are published in the Official Journal. Since basic standards do not

My experience of going through a IEC 60950/UL 1950/CSA 950

Except under special circumstances, the USNEC does not use color coding for

According to BSI, the title of EN50107 is
"Signs and luminous-discharge-tube installations operating from a no-load
rated output voltage exceeding 1 kV but not exceeding 10 kV"
which looks like a standard applying to luminous advertising installations
and the like.
