Note that your picture ...Normal Operating Pressures for Common Refrigerants. For instance, R-22, a common refrigerant, usually sits around 75 PSI on a mild 80-degree day. R-410A, the new kid on the block, runs a bit higher, around 125 PSI. These are ballpark figures, of course. Always check your manufacturer’s specs for the real deal. Factors Influencing Normal Pressures

Physical Properties Of R22. In parallel to using the R22 PT chart, professionals will usually need to know some of the following R22 physical properties: R22 liquid density at -69°C: 1.49 g/cm 3. R22 gas density at 15°C: 3.66 kg/m 3. Triple point temperature: -115.76K. Critical pressure: 49.36 bar. Heat capacity ratio at 86°F: 1.178253.

The manufacturer's instructions rule in this case, as there are a few variables. However, our code (B52) sets the minimum design pressure for R410A to 236 psig for the low side, and 444 psig for the high side. (design can be higher, but not lower.) Your test at 450 psi is probably just fine, but 500 shouldn't hurt it.
