Starting a Test: Pressure Decay Leak Testing – Part 5

In Part 5 of the Zaxis Pressure Decay Series, we move from setup to action: running your first leak test and using it to define a baseline for good parts.

You’ll learn how to:

– Run an initial leak test and interpret the results

– Create a “master” non-leaking part to use as a testing reference

– Observe how pressure, decay, and timing behave during a live test

– Distinguish normal thermodynamic decay from actual leaks

– Compare good and defective parts to identify true leaks

– Fine-tune timing and test steps for more accurate, repeatable results

This section focuses on performing real tests, analyzing data, and building a reliable standard to guide all future leak testing.
