Hi Greg -
Take a look at MIL-STD-883, Method 1009.8 Salt Atmosphere. Although
this method is written around testing parts, finishes, etc. it can be
done on functional assemblies provided you and your customer agree on
what will simulate the use environment. We have done this test with
modifications on functional electronics for customers with salt water
concerns (you would be surprised how wet it is on a ship in the
Pacific!). You don't want to use the test method blindly but it could
be of use to you. Good Luck.

OFFICE MEMO ASSY/TEST: Salt Fog Test Date: 2/5/97
We have been asked to conduct a Salt Fog Test on some assembled, functional
boards, and I have some questions. First, I'm not sure that this is really
an appropriate test to run. I've found method 509.3 in Mil Std 810E (July
89), but nothing else. It sounds pretty tough to control. Are people
actually conducting this test now, or are alternative assembly and chassis
level corrosion tests being specified? What test labs are equipped to
perform them?
I would be grateful to learn from anyone who is doing this test now.
Regards,
