I've looked at that Intel webpage disclaimer, and it really looks like
something invented by their legal department to get out of EMC-testing
their eval boards.
It isn't worded in a way I would recommend. I did tell you that getting
a straight answer from anyone on this issue seems to be impossible: it's
firmly in the 'too difficult' folder.
Still not sure what decision to make on this one. Designing a board to
pass EMC tests (yes, including ESD!) without a metal enclosure might
not be easy or even possible in some cases, so we might just take our
chances and do what Intel and others do: mark it CE for RoHS II, and
include a big disclaimer that the board is intended for engineers who
will use their own judgment to mitigate possible EMC issues
You need to be very careful with the wording. If the product is
extremely unlikely to produce significant emissions, say so. If it
would be best to use shielded cables, put that in the product documents.
It's very unlikely that regulatory authorities would be concerned about
immunity issues UNLESS the product is something like a motor controller,
where a lack of immunity could cause hazardous malfunction.
