INCORRECT...
There IS a test to destruction, but a 5 (3 to 6, depending on the manufacturer) year...hydrostatic "check" is NOT, I repeat NOT a test to destruction !!
Another mention. ALL, I repeat ALL normal, inexpensive...carbon fiber...air cylinders ARE...aluminum, NOT...carbon fiber. A cylinder is formed, then the carbon fiber is overwrapped over the aluminum. LOOK IT UP...............
There isn't many airgun shooters that could afford an "ALL" carbon fiber cylinder (tank, bottle, whatever you want to call them).
I don't know where you've gotten your testing information, but I KNOW that the Aerospace industry does NOT follow your specs ! Been there !
I've witnessed cylinder (aluminum and REAL...carbon fiber) tests to recert., I've witnessed fiber strap testing for recert and to destruction, I've witnessed stainless steel cable testing for recert and to destruction.
So yeah, I've seen a little testing in my 30+ years in the Aerospace world.

Mike,
Our reference to CF Bottles is the aluminum liner with the carbon fiber overwrap, I do not believe there are any 100% carbon fiber bottles, even LOX bottles are lined.
Nobody said it was a test to destruction, I said hydro testing on carbon fiber (wrapped) bottles is a destructive test.
I've seen and done hydrostatic testing and yes, aerospace also follows DOT rules for pressure vessels.
