George, I'm very surprised. All of the pressure vessels I've ever
worked on over the last 30 years that were located inside the USA have
had either DOT or ASME certification. I don't have a reference for you
at the moment, but I've written a note about this issue to a past
president of ASTM to get his input. I'll get back to you with his
response.

Meanwhile, could you tell me exactly what the stamped ratings on the
shell say that you are taking on trust?

Fellas,

Here's the current FAA guidance on the subject: (HBAW 02-01B)
http://www.faa.gov/library/manuals/e...300/hbaw/2002/

An excerpt below, but please read the whole bulletin in the link above
as this policy should not be taken out of context. Most IA's will not
sign off an annual on an aircraft with an out-of-date hydro.

"C. Title 49 CFR parts 171 through 180, Hazardous Materials Regulations
(HMR), pertains to the retest and inspection of cylinders in
transportation in commerce. However, cylinders used as components in
aircraft are not considered to be in transportation in commerce when
installed in an aircraft. As a result, the retest period for cylinders
used as a component of and installed in an aircraft is not subject to
the HMR. However, 49 CFR part 180, § 180.205, formerly part 173, §
173.34(e), would apply to a cylinder that is removed from the aircraft
and offered for transportation as an article of commerce. In this case,
the cylinder must include the appropriate exterior packaging and hazard
communication requirements (i.e., shipping papers, marking, and
labeling)."
