"Groove" -- Moisture, i.e. humidity testing methods and criteria for mil-spec hardware are described in MIL-STD-810E Method 507.3 ... equipment, cycles, etc are spelled out. However, no pass/fail info is included. They assume your staff Environmental Test Engineer can decide that. If you're like most of us, you don't have a specialist on staff ... Check MIL-STD-810 Revision C or D [these are earlier versions of 810] for some guidelines. On the fungus test, MIL-STD-810E Method 508.4, describes testing procedures, including which fungi you should buy for test, etc. etc. The testing is involved, expensive, and not many labs do it. When I've had to do fungus inert verification on mil-spec hardware (this should also work for commercial) ... I review the bill of materials in the assembly in question, determine what types of elastomers/polymers are included and check them against the list of "Known fungus-inert materials" in MIL-STD-454, Requirement 4 ... as long as you only have fungus inert materials in your assembly, there's no need to test ... the list of such materials is not terribly restrictive. If you'd like a copy of any of this stuff, please email me your fax number or address. Good luck! S.
