I've interpreted the EMC statement in the Annex of ICES-003 as suggested

Interference-Causing Equipment Standard for Digital Apparatus, ICES-003,
QA #10, says that the ICES-003 regulation is met with
Hello George:
If you fail the high pot test. You should refer to your transformer
manufacturer to see if they are IEC950/EN60950 compliant or not. For
instance IEC 950 calls for Australian high pot test of 2.5 KV if you have
1.5 KV transformer, then your are more likely susceptible to failure.

What you have said does not actually contradict my own statement (and maybe
that wasn't your intention!).
One must not confuse the requirement to draw the instructions up in one of

George,
Do you have transient voltage surge supressors. Maybe this is why
you failed the hipot. The standard allows you to pass the Impulse
Test in lieu of hipot. Try this method.
Regarding insulation between TNV-3 and SELV/Earth the standard
allows you the following alternatives routes to
In the U.S., 19 and 23 racks are pretty much the standard (and don't
forget the Bellcore hole spacing), yes?
How about in Europe? I've heard they use 19 and 21 racks (or their
metric equivalent). Is one size typical for data applications, and the
other typical to telecom applications? How
