Where is this defined?


It's defined by the sign and some common sense.


Which common sense is that, Tim? How would a VFR departure know
that there might be another airplane on a 10 mile final using the ILS
system at a non-towered field?

A tower won't instruct you to hold short of the ILS critical areas with
an aircraft on a 10 mile final.

If you can see an aircraft on approach (or hopefully are clued in by his
CTAF reports) if he is close enough that you decide you need to hold
short, then the common sense decision would be to hold short of the ILS
critical area signs.

It's the conservative and safest option. And, it's what the FAA airport
folks hope you will do.
