Thank you, Jim, for this background. FCC Rules Part 15 state that if
any such preventive measures are taken, the user should be advised
and/or shielded cords must be provided with the equipment. I always
feel very uncomfortable when standards are written in such a way as to
arbitrarily prohibit the usage of certain equipment or parts. I am
pleased to see that this is not the case here.
The fact that the use of shielded cords and cables may not be the best
EMC practice should not be transformed into another fact that shielded
cords are not allowed.

If memory serves me correctly, the old EMC regulations that existed in
Germany long before the EMC Directive came into being (remember VDE
0871, VDE 0875, etc...?) included the provision that if a shielded
power cord was needed to meet the emissions limits, then the cord had
to be a non-detachable type.
I'm aware of no similar restriction or prohibition of shielded power
cords with regard to the EMC Directive. However, if such a cord is
needed to meet the EMC Directive requirements, I would suggest
including a statement to that effect in the operating instructions for
the equipment.
(BTW, a good source for shielded and filtered cordsets is EMC/EUPEN,

It is my understanding that shielded power cords are not allowed on
products in European markets. As I recall, the rationale is that if a
cord is replaced, there is no guarantee that it can, or will, be
replaced with a shielded cord.
