US Navy Environmental and Other
(OP)
We have been asked to bid on a custom amplifier for a US Navy application. All of our work to date has been commercial, ship board Navy is entirely new territory for us. Can some one direct me to documents on environmental requirements and testing. Also, preferred parts for connectors, wire,etc., and water cooling plumbing.





RE: US Navy Environmental and Other
Typically, something like:
MIL-STD-167 for shipboard vibration
MIL-S-901 for shipboard shock (only for ship-critical systems) (the "hammer" test)
MIL-STD-810 for most other environments, like salt fog, acoustic, temperature, humidity, etc.
MIL-STD-461 for EMI/EMC
MIL-STD-2164 for environmental stress screening
Interface requires should likewise be in your procurement specification.

An example (just an example) is MET Laboratories, Inc. - was used by one of our vendors once or twice. Obviously you'd probably choose one close to you.
Costs might be on the order of mid 5-figure$, up to the low end of 6-figure$. YMM certainly V.
You should probably approach them as soon as you have a preliminary design, and start to get quotes and select them.
With luck, you might even be able to tap into their expertise to review your design. But some may have policies against that (keep an arm's length etc.).

re. 901 - The test was meant to simulate the ship getting hit, as this was a problem in WWII, when ships were hit and the impact shocks damaged critical systems on the ships. 901 covers 2 types of testing for simulating such shocks; a "hammer test" and "barge test." The former puts the lighter UUTs on an "anvil" which is hit by a "hammer," while the latter places the heavier UUTs on an actual barge in a small pond where actual explosives are used. Rumor had it that the Navy was only accepting barge testing, even for lighter UUTs, but our IR&D was terminated before we got that far.
