Volume / Pressure Conversion

All,

I know this is not necessarily PCDMIS related but it is job related.

The note on the print says:

Max leakage at 5.5 bar: 5 cubic mm per second at atmospheric pressure.

I have a tester that can input 80 psi and I can measure the drop in pressure. For instance I can watch for 1 min and see that it drops to 70psi. Is there a way to convert this into something I can use to satisfy the print callout? Any help would be greatly appreciated.

I'm thinking you need a vacum, the atmospheric part indicates the leak of concern is from outside in not from the inside out as your tester would do. Interesting, you'll need a certified master orifice (have fun with that one ).

I am pretty sure that it means it is leaking "into" atmospheric pressure which indicate leaking "inside out"
