I'm having a tough time finding the proper ISO standard for Pressure Testing. Specifically I'm trying to figure out if within this standard there is a method for testing leak rates with air and being able to connect that leak rate to a hydro-static rate.
I know air molecules are smaller than water, so I would assume for a water tight seal you might still see, say 3 bubbles of air a minute. Or if you pressurized the unit to 30 psi, it would drop to 28 psi in a min and still be considered water tight.
Any help would be greatly appreciated.
Thank you in advance.
