VeriPac 325/LV Leak Test Sequence of Events
| Leak Test Sequence of Events | Package FAILS | Package PASSES | |
|---|---|---|---|
| 1 | An initial vacuum flush is performed to remove any surface moisture or gas contaminants from the test system | NA | NA |
| 2 | A target vacuum is established, as monitored by the absolute transducer | Vacuum 1 Reference or Vacuum 2 Reference is not reached Test ABORTS (gross failure) | Target vacuum reaches Vacuum 1 Reference and Vacuum 2 Reference |
| 3 | Valves close isolating the test system from the vacuum source. The system is allowed to stabilize or “equalize” | NA | NA |
| 4 | The absolute transducer monitors the rise in pressure during equalization and test time | Absolute pressure reading rises above Vacuum 2 Reference Test ABORTS (gross failure) | Absolute pressure remains at or below Vacuum 2 Reference |
| 5 | The differential transducer monitors the rise in pressure (dP) during test time | Differential pressure reading rises above dP Reference Package FAILS | Differential pressure remains at or below dP Reference Package PASSES |
NA = not applicable.
