There are several different tests conducted to ensure a new pump works as desired. The first test is dry vacuum testing to ensure that it holds a vacuum. The pump will be taken to at least a 22 in/Hg (75 kPa) dry vacuum and then watched to see how that vacuum changes over time. That vacuum cannot drop more than 10 in/Hg (34 kPa) in a five-minute time span to be considered passing. The pump would then go through a hydrostatic pressure test to ensure it's structurally capable of containing pressure. Typical hydrostatic pressure tests are done at 500 PSIG (3400 kPa) for a 10-minute time span without any leaks whatsoever for it to be considered passing.
