Vacuum Decay Test

ASTM F2338 Standard Test Method for Nondestructive Detection of Leaks in Packages by Vacuum Decay Method

The ASTM F2338 vacuum decay test method is used for identifying leaks in rigid and semi-rigid packages sealed with porous barrier lidding materials. This vacuum integrity test can be utilized on both rigid and flexible packaging.

Industry Application

Vacuum decay testing is a non-destructive, whole-package integrity test. It is commonly performed on a package where the test sensitivity requirements are high. A vacuum decay integrity test often applies to pharmaceutical or biological packaging where test sensitivities are determined by the viscosity of the media inside. This method of leak testing requires more time to perform than others due to the need for a custom fixture and test method validation for each package.

Frequently Asked Questions

Which industries typically use vacuum decay test per ASTM F2338?
Vacuum decay often applies to pharmaceutical or biological packaging where test sensitivities are determined by the viscosity of the media inside the packaging, which in most cases is a vial.

What is vacuum decay testing?
Vacuum decay is a non-destructive, whole package integrity test. A custom piece of tooling is required to perform vacuum decay testing as well as a test method validation for each package.

Why use Vacuum Decay Test rather than other Container Closure Integrity Tests?
Vacuum Decay testing is more sensitive than other Container Closure Integrity Tests. It is also a deterministic test resulting in PASS or FAIL end values.
