Overview of ASTM F Dye Penetration Integrity Test

The Eyedropper method requires the packages to have an unsealed area that extends beyond the outer edge of the f1299-98. For more information visit www. 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 f1992-98 from the porous material with use of a finger, paperclip, etc. Learn more about the different testing services provided at each location. If wicking does transpire, it may be verified by observing the porous side of the subject seal area.

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.


ASTM-F – Medical Package Testing

The dye solution used in penetration testing will wick through any porous material over time, but normally not within the suggested maximum time. 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. Harmful biological or particulate contaminants may enter the device ast, leaks.

Here is a quick overview of the changes: The dye will have discolored the surface of the material.

Please keep this in mind when developing your studies and validations. The package will be visually inspected for dye penetration after contact with the dye penetrant for f19299-8 specified time. The porosity or lack thereof of the package material determines the inflation rate for the burst test.

The Creep Test provides a test for slow atsm of the adhesive bond similar to a dead weight hanging on the seal. Observe each seal for a recommended duration of 5 to 20 seconds.

Leaks may also result from a microscopic pinhole in the packaging material that is invisible to the human eye. There is no general consensus regarding the level of leakage that is likely to be detrimental to a particular package. Requirements ASTM F testing is limited to porous materials which can atm the dye penetrant solution and prevent it from discoloring the entire seal for a minimum of 20 seconds.

If ASTM F testing is used as the quality control method, the test specimen must consist of a complete packaged device. Packaging must be free of condensation or ast, other source of liquid water. Most commonly, an eyedropper or pipette ast used to apply the dye penetration solution between the transparent and porous materials of the unsealed area. However, since ASTM F testing is designed solely to detect leakage, components that illustrate any indication of leakage are usually rejected.


This pressure creates the force needed to rupture the seal. 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. ASTM F procedure requires that the dye penetrant have good contrast to the opaque packaging material. In the Burst Testair is introduced into the package at a predetermined pressure and flow rate. Place a bead of solution between the two materials along the outer edge of the package seal, ensuring the entire outer edge of the seal is wetted with the dye solution.

A dye penetrant solution is applied locally to the seal edge to be tested for leaks. Water already in the seal defects may render them undetectable with a dye penetrant. Observe the package for any leaks originating from the inside edge of the package seal towards the outside edge of the package seal.
