ASTM-F – Medical Package Testing

Observe the package for any leaks originating from the inside edge of the package seal towards the outside edge of the package seal. Please keep this in mind when developing your studies and validations.

As a guide, each Test Method above recommends observing each seal for a maximum of 5 seconds on a 4-sided package 20 seconds total.

The Creep Test provides a test asym slow shear of the adhesive bond similar to a dead weight hanging on the seal.

Overview of ASTM F Dye Penetration Integrity Test

The dye solution used in penetration testing will wick through any porous material over time, but normally not within the suggested maximum time. There is no general consensus regarding the level of leakage that is likely to be detrimental to a particular package.


Learn more about the different testing services provided at each location. Observe each seal for a recommended duration of 5 to 20 seconds. The package will be visually inspected for dye penetration after contact with the dye penetrant for a specified time.

The Eyedropper method requires the packages to have an unsealed area that extends beyond the outer edge of the seal.

Requirements ASTM F testing is limited to porous materials which can retain the dye penetrant solution and prevent it from discoloring the entire seal for a minimum of 20 seconds.

Because air escapes through the walls of a porous package during inflation, the flow rate must be increased to compensate for the lost air through the walls and create the back pressure in the porous package.

If ASTM F testing is used as the quality control method, the test specimen must consist of a complete packaged device. If wicking does transpire, it may be verified by observing the porous side of the subject seal area.

Leaks may also result from a microscopic pinhole in the packaging material that is invisible to the human eye. In the Burst Testair is atm into the package at a predetermined pressure and flow rate.

Most commonly, an eyedropper or pipette is used to apply the dye penetration solution between the transparent and porous materials of the unsealed area. The porosity or lack thereof of the package ff1929-98 determines the inflation rate for the burst test.


Packaging must be free of condensation or any other source of liquid water. The dye will have discolored the surface of the material. This pressure creates the f19929-98 needed to rupture the seal. Place a bead of solution between the two materials along the outer edge of the package seal, ensuring the g1929-98 outer edge of the seal is wetted with the dye solution. However, since ASTM F testing is designed solely to detect leakage, components that illustrate any indication of leakage are usually rejected.

Here is a quick overview of the changes: ASTM F procedure requires that the dye penetrant have good contrast to the opaque packaging material.


Please contact us with any questions you may have about ASTM F, or if we can help you with any other testing questions or projects. These leaks are frequently discovered at seals between package components of the same or dissimilar materials.

Along the extended unsealed area beyond outer seal edgethe transparent material is separated from the porous material with use of a finger, paperclip, etc. Harmful biological or particulate contaminants may enter the device through leaks. A dye penetrant solution is applied locally to the seal edge to be tested for leaks.
