There is a web site that goes by RAC (Reliability Analysis Center) on
the internet that may have some of data you are looking for.  I have a
problem with 883 because current production processes should be much
more reliable than buying a 883 part.  I am not a statistician, but I am
sure that you can find some that could prove my hypothesis correct.  A
lot of the methods in it should be portable to other testing designs
though.  My biggest problem with it is the visual inspections that
pretty much kill the reliability of the part as compared to todays
systems.  In addition, the more handling you do of the components the
more likely your going to screw them up somehow.  The final thing that I
find hard to take is getting hammered for plastic IC's versus
hermetically sealed components.  Other than that, I think that 883 makes
a good guide to reliability questions.

	If you haven't abandoned all military documents, you could use as a
reference Mil-Hdbk-781 for systems and Mil-Std-883 for components.  They
give
test methods and analysis of data.
	Or, there is the JEDEC series of standards (JESD22-xxxx-x) available
from EIA and Doug already mentioned Bellcore.  It's always good to
reference
your source when developing a test plan.

| Thank you in advance for anyone willing to answer.
