Refer to EN50116:1996, Information Technology Equipment, Routine Electrical
Safety Testing in Production.  It calls for Electric Strength tests as well
as Ground Bond tests on all products.

> I believe that this question is too general.  In general, I would not
feel comfortable not doing 100% dielectric testing, but you must look at
your particular construction to figure this out.  For instance, refer to
table 6A concerning insulation in printed boards.  Most cases require 100%,
or Routine electrical strength testing.  Other questions to ask..
