ASTM F1140 describes creep testing. Can creep testing be correlated with any of the integrity tests?
It is important to note that creep/burst testing conducted under the guidance of F1140 is a test of whole package seal strength, rather than a test of package integrity. While important data are obtained from seal-strength testing (through the creep test) that may allow one to draw conclusions relating to overall performance (integrity) of a package, the two cannot be correlated. Other tests that do correlate to package integrity (referenced in the webinar “Package Integrity: A Look at False Alarms” and repeated here) are ASTM F1929 (Dye) Test Method for Detecting Seal Leaks in Porous Medical Packaging by Dye Penetration, D3078 (Bubble) Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission, F2228 (Trace Gas) Test Method for Non-Destructive Detection of Leaks in Medical Packaging Which Incorporates Porous Barrier Material by CO2 Tracer Gas Method, F2095 (Pressure Decay) Test Methods for Pressure Decay Leak Test for Flexible Packages With and Without Restraining Plates, F2096 (Bubble) Test Method for Detecting Gross Leaks in Medical Packaging by Internal Pressurization (Bubble Test), F2338 (Vacuum Decay) Test Method for Nondestructive Detection of Leaks in Packages by Vacuum Decay Method, F2391 (Trace Gas) Test Method for Measuring Package and Seal Integrity Using Helium as the Tracer Gas, which all can be utilized to determine package integrity.
