Part Material: Pressure Decay Leak Testing – Part 3

In Part 3 of the Zaxis Pressure Decay Series, we explore how the material properties of your test part can influence pressure decay results. You’ll learn how to:

• Understand the difference between rigid and flexible test materials
• See how material flexibility affects internal pressure readings
• Recognize “elastomeric creep” and how it can mimic a leak
• Adjust your test setup to account for part movement or stretching
• Prevent false readings caused by material compliance

This section helps you identify and control the impact of part materials to ensure more accurate and consistent leak test results.
