There is no boundary, just a continuous transition.  So when you ask 
what "the 'boundary'" is, the answer depends on what _you_ mean by the 
boundary.  To answer that, you have to specify quantitatively where you 
think that relativistic effects become significant, and you haven't done 
that.

However, even without that information I've given about the most 
complete answer possible, so I don't see what your point is.  Did you 
want your question answered, or did you want to try to argue?

It is the standard meaning.  I'm suspecting you're just trying to be 
difficult at this point.
