Over the years, I have seen some outstanding attempts at refurbishing kit ... sometimes even (claimed to be) by the original manufacturer. But close examination has
always revealed it to be not quite "as new". So, again, I guess we're back to definitions. In this case:- "original specification".
So, are we saying that if the spec* hasn't changed (the normal case, I would have thought), we're home and dry. But if "different components" (definition required) have been used, then we're in ... er, deep water?
Let's be clear that I'm coming from a different perspective here (that is, not the default "NHS environment" assumed by many who visit the forum):- that of the "second-hand", donated, ex-medical (
eg, veterinary) view of things.
So ... components meeting original specs? So like-for-like
cannibalisation is OK, then? (phew)
And ... which regulations prevail when (or if) the kit is sent overseas?

In this context, when we say "spec", do we really mean "performance"?
