I know, it is confusing. But you got the date right. The "strange
symbol" is a manufacturer's marking, I believe (usually, I see a
triangle with letters inside), and the hydro dates are on either side
of the mark. That would be the "born on" date. Purchase date has
nothing to do with recertification. So, your tank would have to be
rehydro'd before 01/04, not through 1/04.

While you might be confused, I would hardly say you're oblivious,
cause you actually care to post and ask about it.
I've seen guys try to fill tanks 2 or 3 years PAST hydro date. That's
oblivious to me.

I've seen and heard of guys doing outright foolish things to their
tanks...the one that stands out the most is the "slam fill - rapid
cooling" technique. You know how if you do a fill fast, the tank gets
hot? these doofuses (doofi?) will dunk their tank in ice water to cool
it quickly! OMG, I'm surprised they haven't killed themselves yet. It
would surprise me if those tanks pass hydro. Hell, it would surprise
me if they even made it to hydro without rupturing first!

Paintball players fill the tank way to fast, and the makers of the tanks have
said so. The rapid fill makes the tank get to hot, which will make it far less
likely to pass hydro.

When a scuba tank is filled, it is filled fairly slowly and put in water to
keep it cool.

But what you said it correct, doing a rapid fill and dropping it in ice water
is asking for trouble.

This thread reminded me that I need to pick up my scuba tank. It was suppose
to be finished being hydroed today.

Maybe your SCUBA shop differs from mine but the one I used in KC
(Kansas City, MO) all the time gave me hot fills almost every time...

I need to get my 68/4500 AA Apoc hydro'd

January 2001 is the "BORN ON DATE".
The strange symbol is the testers certification identification.
Yes, recertification is from that date.
The actual DOT-E 10915 that the following letter refers to states:

"TESTING: Cylinders retested prior to May 11,2001 must be retested within
36 months of the retest date marked on the cylinder. Cylinders retested on or
after May 11, 2001 must be reinspected and hydrostatically retested at least
once every five years."

Luxfer carbon composite cylinders are first to be granted five-year retest
cycle by DOT RIVERSIDE, Calif. (May 21, 2001) Luxfer Gas Cylinders announced
today that the U.S. Department of Transportation (DOT) has determined that
Luxfer carbon composite cylinders need to be retested only every five years
instead of every three years. Luxfer is the first and only U.S. cylinder
manufacturer to be granted this extended retest cycle, which applies both to
new carbon composite cylinders and cylinders already in use. The DOT decision
covers all Luxfer cylinders manufactured to DOT Exemption DOT-E 10915, which
includes the entire Luxfer carbon composite cylinder product line for the U.S.
These cylinders are used primarily in firemen s self-contained breathing
apparatuses (SCBA), medical oxygen systems, aircraft inflation systems and
paintball guns. DOT requires that all composite cylinders be periodically
re-qualified for continued use. This process includes a visual inspection and a
hydrostatic retest. Luxfer carbon composite cylinders now must be re-qualified
every five years, while all other composite cylinders must be retested every
three years. This longer retest and requalification cycle will be a major
benefit for owners of Luxfer carbon composite cylinders, said Ed Morris,
general manager of Luxfer s Composite Cylinders Division. Because they ll only
have to get cylinders retested every five years instead of every three years,
they ll do half as many retests over the 15-year life of a composite cylinder.
That will not only generate significant cost savings, it will greatly simplify
inventory management, paperwork and administration. Morris noted that this
longer retest cycle is the latest in a succession of firsts achieved by
Luxfer. In 1996, we became the first company to introduce a carbon composite
cylinder to the U.S. market, he said. Then in 2000, we were the first to
introduce a composite smart cylinder equipped with a programmable transponder
tag that improves cylinder tracking and identification. For more information
about Luxfer carbon composite cylinders, call Luxfer at (909) 684-5110 or

hope this helps!

Something other than drill a hole in it?

TC, Tansport Canada. Certification requirement, req'd for filling in Canada

DOT dept. or transportation Same, but for U.S.

DK23577 LUXFER I believe is the Danish equivalent, but I could be wrong.
