Eddy, assuming the ram has been built using standard cylinder tube, rod and end caps that your employer would normally use then it sounds very much a standard ram to me. I would suggest that you ask your employer for a certificate of conformity for it to confirm this fact. Thank you Alan, that just about sums it up.

Mack, all pneumatic systems are considered as gas systems rather than liquid even though the CO2 is stored as a liquid and sometimes injected into rams as a liquid. This is because the CO2 liquid rapidly boils off as a gas when the pressure drops.
