Dye penetration testing provides a visual method of evaluating package seal integrity and identifying potential seal failures. A dye solution containing a surfactant is introduced into the package and brought into contact with each seal for a specified period. The seal is then examined for evidence of dye penetration.
Smithers commonly performs dye penetration testing for medical device packaging, with the appropriate test method selected according to the packaging material and application.
- ASTM F1929 – porous packaging materials, including Tyvek® pouches
- ASTM F3039 – non-porous packaging materials, including foil structures
- EN 868-1 – non-porous packaging applications
