Dye Penetration testing is used to find channel leaks through the seals formed by a transparent film and porous material. This qualitative test will find channel leaks through a seal as small as 50 microns. To conduct Dye Penetration testing, a dye and surfactant solution are injected into the medical device packaging. Each seal is exposed to the dye penetrant for 5-20 seconds. During this time, the trained operator will inspect the seals for dye fluid coming through the seals. The release of dye through a channel leak would constitute a failure of the package integrity, and according to ISO 11607, a breach of sterile integrity.
