I'm looking for a word to name an item that is outside a set tolerance. For example, I have to place a signpost within 3 feet of a building but I put it 4 feet away. That signpost is outside the tolerance, it goes over the allowed threshold, it is a(n)...
I was thinking it's "an outlier" or "a deviant" but those don't seem to quite meet the case, and a thesaurus search didn't turn up anything else.
It's for a term in a software dialog, so I'm looking for something short and sweet. Like "Process Deviants (Y/N)" - but not deviant because a) it sounds stupid, and b) it doesn't imply over a tolerance limit (which is important here).
Any suggestions? I'm hoping that there is such a word and that someone knows it!
