People need to get this "rating applies to everything" idea out of their heads.
Rating is the working pressure a manufacturer has decided to certify a part as safe for the customer to use it at.
Therefore, many things do not have a rating - although BBQ cylinders DO have a test pressure (although, not intended for customer use*), and usually an overpressure valve.
*Self re-fillable tanks (rather uncommon, at least for me) are filled by volume or weight, not pressure.
Everything that can be pressurised can however have a "safe working pressure" (or SWP for short).
The word "rating" only applies when that SWP is one that the manufacturer has certified it for the customer to use it at.
Still, what the SWP is on a tank like that, I can't immediately remember.
