Pressure Decay Leak Testing

An overview of pressure and vacuum decay testing concepts, equations that are important in understanding how the tests work and how to design the appropriate leak test for your product or package, how statistical analysis can help you with process control, and other useful topics.

Calibration versus Decay Measurements (PDF format only)

This paper presents a definition of each concept and a discussion of the difference between a leak tester's resolution (its ability to detect pressure change - decay - during a predetermined test time) and its accuracy regardingcalibration to a known standard (its ability to reproduce a test pressure consistently at the beginning of the pressure decay leak test).

In addition, a discussion is presented that examines issues related to pressure decay leak testing including environmental influences, factors limiting leak tester resolution, and the physics behind the pressure decay leak test.
