It seems I acted too quickly.  Annex T of IEC 60950 describes these ratings,
at least the meaning of the second "X" in IPXX.  We are now looking for the
base standard IEC 529 for the meaning of the leading "X".

Earlier post:

I have misplaced a file that explains the various IP ratings
for ITE as to the above subject.  Does someone have these to
post, or a website listing these?

I have been asked about IP54 and IP64.

Many thanks,
