By 'troublesome' I meant 'emissions over, or too close to, the limit,
that can't be easily reduced.' If the emissions are low enough or can be
made so, why bother to ask about need to test?

officer that you drove too fast for only a few minutes by year if
caught over-speeding? And what did he say ?
Ports do not need testing only if inoperable at all. And even than,
from a technical point of view it may generate interference. In my
opinion, testing requirements end completely when a port is not
accessible to the end-user.
And the criterion is not _troublesome_ emissions, the requirement is
_over-the-limit_ emissions.
Like speeding by car, driving beyond speed-limits does not need to be
troublesome (by the absence of other cars for example, or by night).
Nevertheless, any speeding limit is enforced even if not troublesome.
But at the end, it is the manufacturer who decides if creating
emissions over the limit is acceptable or not. But do not complain if
you get caught.

Do you even need to justify not testing,if it doesn't produces
troublesome emissions? The only justification I can see might be that
it is used only for periods of a few minutes a few times a year.

A device has a wired network port used for de-bugging only.
The port is not used during normal operation of the device.
Any opinions on whether or not this port should be tested?
