Same as how a car can stop running, just because you forget to renew its registration.
Actually, it's because the DOT is (supposedly) reviewing the numbers each time the exemption is renewed, to see that problems aren't developing with the tank.

Please forgive my ignorance in matter, but how can that actually affect the integrety of a tank?
If they were acceptable at the time of manufacture according to DOT, how can they suddenly become defective?
That's probably a rhetorical question, but it begs to be asked.

K, I'm not sure when PST designed the tanks nor when they got their first exemption but if I am reading oxyhacker's post right, they, the DOT, is gathering data every year and seeing if the tanks are indeed holding up or if the tanks should have a limited life span, due to documented failures.
Am I not correct that in Europe, the fiber wrapped 4,500 psi tanks have a specific life span EVEN if they test OK?
I guess that part of the exemption renewal process is to verify that the tanks should have no restrictions.

I've emailed PST and asked 'em to have a look at this thread and give us the straight word.

It's the same in North America - fiber-wrapped tanks have a 15-year service life and must be tested every 3 years.
There are plenty of problems that can develop in a cylinder design over time, so it makes sense to review the exemption every once and a while to see that the tanks are still working as they should. Neck cracking in old aluminum tanks are a good example (although not serious enough to disqualify them from service).
Which means we should hear from them in about 6 months. Make that 12 months. Maybe 18 months.Rick Murchison:
PST makes a great tank and all of their staff that I've met have been nice but they are trying to make a go of it in an industry that has been in the outhouse in this country for decades.
Everybody laughed at me when the new tanks came out and I started buying LP104's... :11:
