Hello,

I would like to test an 8" valve according to ANSI Class VI Leakage criteria. We normally do a hydro and measure leakage rate. However, I would like to use air for an upcoming job in which we have to test at vacuum. Can anyone tell me if there is a conversion or rule of thumb for volumetric leakage rate to pressure drop? Thanks for the help.
