Dye Leak Test
ASTM F1929 Standard Test Method for Detecting Seal Leaks in Porous Medical Packaging by Dye Penetration
The dye leak test evaluates seal integrity. It is typically performed during sealer validation or for in-process maintenance. The sensitivity of this test is 50 microns. The test is performed using a specialty dye solution to identify minute defects within a sterile closure seal. NOTE: This test is not intended to be a whole-package integrity test.
