ASTM F1929 - Standard Test Method for Detecting Seal Leaks in Porous Medical Packaging by Dye Penetration

This test method defines materials and procedures that will detect and locate a leak equal to or greater than a channel formed by a 50 µm wire in package edge seals formed between a transparent material and a porous sheet material. A dye penetrant solution is applied locally to the seal edge to be tested for leaks. After contact with the dye penetrant for a specified time, the package is visually inspected for dye penetration.

Three dye application methods are covered in this test method:

• Injection method
• Edge dip method
• Eyedropper method
