I don't think the hydrostatic test is a FAA requirement. IIRC it is a
requirement to have the tank filled by an authorized filling station.

There's no requirement to have it filled by an 'authorized' station in
the
regs either.

That's correct. I have mine filled at a welding supply house unless I run
out when I'm away from home. Technically the filling station can only fill
tanks for which they have a license and aviation, medical, and welding
oxygen tanks are all different (even though the oxygen source is all the
same).

The source is the same. But the handling until it's in your bottle is
different.

Nope, the only thing that is different is the paperwork.
