Rusty's got it right.

Let's say you never put your RV through loops while in the initial test 
phase. Does that mean it's illegal do do loops in your RV from here on 
out? Not at all. Simply put it back in Phase 1 (log entry), fly to the 
designated Phase 1 test area, do loops. Fly home, make notation in log 
and put it back in Phase 2.
Of course, to do a professional job of it, you would wear a chute, do 
loops at different entry speeds, W&B loadings, etc. All of course within 
Van's design specs. If you expand the testing envelope outside the 
designer's specs, be ready to use the chute, and do careful inspections 
of the airframe (popped rivits, bent metal), after each flight, and as 
Rusty mentioned for flutter testing, increase the envelope in small, 
small increments. Don't just go out, put it in a dive to 250 mph and 
slap the stick :)
