The "solder sample" I am assuming is the board used for solderability testing
Yes the holes are filled with solder, but they have not been "stressed" as
required
by the specifications.  . Solderability testing is much, much lower
temperatures and for less time.

That is why you cannot just microsection solder holes and say you have
evaluated
after thermal stress.
