Egregious? Not necessarily. For our products, we will discharge to internal
parts that the user can come into contact with during normal operation or
maintenance. For example, if the user is expected to open a cover to change an
ink cartridge, remove a paper jam, or perform some other routine procedure, then
we would discharge to the areas exposed to the operator when the cover is open.
However, we would NOT discharge to an internal area that is not normally
accessed by the operator, such as a cover that is only expected to be removed by
a qualified service or repair person.
Note that EN 55024 also states specifically that you are not expected to
discharge to exposed connector pins. I guess that would, in fact, be
egregious.

Subject: Question on internal ESD testing
Hello,
Does anyone in this august group apply ESD discharges INTERNAL
to a product as required by EN55024.
I consider this just a tad egregious - don't you?
Thank you
