Vacuum Decay Leak Test

A vacuum decay leak test is a cost-effective non-destructive testing method used to detect leaks in parts, packaging, and industrial components. Compared to traditional dunk tests, vacuum decay leak testing is completed quickly, yields certain and reliable results, and significantly reduces the opportunity for variability and human error.

How Zaxis Vacuum Decay Leak Tests Work

Vacuum decay leak tests deliver many advantages to your production, such as producing results with resolution up to the 5th decimal place or 0.00001 PSI, allowing for fast test cycles. Zaxis air leak testers are built for usability and repeatability. On top of being customized to your requirements, they are integrated into your line and complete testing in a few straightforward steps:

  1. Connect your part to a Zaxis leak tester using the appropriate fitting or fixture. The FILL stage begins, and a negative pressure (vacuum) is applied to your part.
  2. Once the desired negative test pressure has been reached and the fill timer has ended, the SETTLE stage commences. This phase accommodates for part stretching or flexing.
  3. Once the settle time ends, the vacuum decay TEST initiates, and a pressure sensor measures any increase in vacuum pressure.
  4. When the vacuum decay test is complete, the VENT stage begins. Any remaining negative pressure in the system is vented to atmosphere.
  5. If the vacuum decay of your part remains within the pre-set specifications, then your part PASSES, and a green light illuminates. If the vacuum decay of your part falls below your lower limit, then your part FAILS, and the red light illuminates.
