Nominal bursting pressure is about 250 psi.
IF you wanted to ascribe a rating to it based on the typical saftey margains of PVC pipe, it'd be rated at 60-80 psi.
If you want to pretend you are nasa, fill it to 200 psi.
Of course, I doubt the manufactuer has the quality control that nasa does.
Personaly, I think I'd emulate the russians and keep a fair saftey margain, like 125 psi or so.
It's not a pipe-like ratio, but it's pretty safe.
Oh, and you might want to hydro test it to 200 psi, just to make sure.
(Ever wondered why nasa's hardware costs so much? Now you know.)

I have ran 2L bottles at 125psi(8bar) many times and have only ever had one failure and that was with an old bottle but i have used the same 2L bottle for over 500 shots at 125psi(8bar) and had no problems
