Key points for selecting vacuum maintenance test equipment
For vacuum-hold testing, first define the temperature and isolation conditions and compare empty- and loaded-chamber records. A pressure-rise result alone cannot distinguish leakage from sample outgassing.
For vacuum hold, compare empty and loaded chambers to avoid misidentifying outgassing as leakage.
Equipment decisions
-
Compare empty and loaded pump-down curves to distinguish leaks, sample outgassing and vapour load; one pressure-rise result cannot by itself establish seal failure.
-
Record pressure-hold behaviour at the same temperature and isolation conditions, then inspect door seals, valves, joints, gauge lines and the pump.
-
Repeat baseline and loaded checks after servicing or seal replacement; retain before-and-after curves to confirm recovery of the drying endpoint and atmosphere stability.
Trial and acceptance
Record the initial sample condition, loading layout, recipe version and raw measurements. Agree the acceptance endpoint before the trial; repeat at challenging load positions and compare the finished material result.
