My last company made equipment for monitoring the condition of oil/gas well drill holes (both Closed Hole metal drill pipes and Open Holes where it was part of exploratory drilling equipment in the surrounding rocks, etc), but it did not make submersibles.
However we tested the equipment on the surface as if it were "normal devices" because it had to be operated there for preparation and test purposes. We did not attempt to test it as it would be when it was in the drill pipes or holes because it would then be surrounded by either a metal Faraday cage or vast areas of solid rock and so on - where there was little or no chance of it interfering with, or being interfered by, anything else. Also, AFAIK, there had never been any reports of interference to, or from, other equipment, and that would also have been part of a defence against any accusations that it did need to be tested in the down-hole configurations.

If not I would look to test it as for any normal device.

I'm guessing conducted radiation is still a concern, but what about radiated and immunity?? Does it matter if it's 30 feet below or 3 feet??
