Larry,
 Couple of questions for you.
1. What is your customers specification for workmanship?
2. Was the component vender qualified by your customer and if so how?

 You are correct in the fact that the supplier will probably not accept
that these parts are bad. I have seen in the past where component
suppliers will try to "dis-qualify" your process because their
components are not performing. This can be a touchy area, good luck.

Technetters,
How does your Quality department test components for solderability? Do
they still test to the MIL-STD-202, MIL-STD-750D which is a soldering
iron or solder pot test? I'm looking to have my company test to IPC/EIA
J-STD-002A 4.2.5 "test S- surface mount process simulation test." This
test basically is placing solderpaste on ceramic and running it through
the reflow oven. My thought is that this is how these components are
going to be used, so this test better reproduces the actual world.

But, many component manufactures still use one of the MIL standards. As
you all know,  components will solder much better using the MIL test
then the IPC test.I can see there is gonna be difficulty in getting them
to accept them back as defective. How do you handle this? Do you test to
the MIL test because thats what the manufacture does? How would you
handle the issue of the component passing the MIL test but failing the
IPC test Knowing that the IPC test reflects your manufacturing process?

Larry
