Hartley,
Sorry, but I don't think you can get it done. All the responses to
your question tell you where to get it hydo tested. That is not your
porblem. None of those places will test it - or they shoul not - as it
does not have a DOT certification. That is the problem with the
European bottles. Unless you find someone who does not follow the
rules ( and if you do you will probalbly have to take it back to them
each time as no one else will do it, they might put a phony DOT # on it
but if they will do that I would be worried about the quality of their
testing) or does not know the rules, which I have not found to happen
very often, you can not get it filled. If you have been getting it
filled so far you are lucky. If you have the small bottle you can
usually change to the US DOT "D" size. You may have to sand the
bottle sleeve just a bit. I have had this problem with two German
gliders.

Good luck

Does anyone out there in r.a.s. land know how to get a German Oxygen
cylinder recertified to DOT specifications, and a place to get it done? I
think it is out of date, and I got I with the glider, a DG800B. It appears
to be in good shape-no dings or scratches. It has no DOT cert number on the
neck, and was imported with the glider-factory installed.

Thanks in advance
