ASTM F1929 DYE PENETRATION TEST PDF

Posted In Art

ASTM-F describes the standard test method for Detecting Seal Leaks in Porous Medical Packaging by Dye Penetration. The current test method is ASTM F dye penetration. • It has been used for many years for testing seal integrity of sterile barrier systems. • Round robin. While the traditional ASTM F Dye. Penetration standard is Triton-X used in dye penetration testing is a non-ionic surfactant with both a hydrophilic.

If wicking does transpire, it may be verified by observing the porous side of the subject seal area. The Creep Test provides a test for slow shear of the adhesive bond similar to a dead weight hanging on the seal.

Harmful biological or particulate contaminants may enter the device through leaks. Leaks may also teest from a microscopic pinhole in the packaging material that is invisible to the human eye.

Observe each seal for a recommended duration of 5 to 20 seconds. Historical Version s – view previous versions of standard. Uncoated papers are especially susceptible to leakage and must be evaluated carefully for use with each test axtm.

Learn more about the different testing services provided at each location. Most commonly, an eyedropper or pipette is used to apply the dye penetration solution between the transparent peneetration porous materials of the unsealed area.

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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Either is to be regarded as standard. 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.

Leaks may also result from a pinhole in the packaging material. The presence of a number of small leaks, as found in porous packaging material, which could be detected by other techniques, will not be indicated. However, since these tests are designed to detect leaks, components that exhibit any indication of leakage are normally rejected.

Water already in the seal defects may render them undetectable with a dye penetrant. The porosity or lack thereof of the package material determines the inflation rate for the burst test. Along the extended unsealed area beyond outer seal edgethe transparent material is separated from the porous material with use of ;enetration finger, paperclip, etc.

Here is a quick overview of the changes: A dye penetrant solution is applied locally to the seal edge to be tested for leaks.

Refer to Appendix X1 for details on wicking and guidance penetratuon the observance of false positives. For more information visit www. The package will be visually inspected for dye penetration after contact with the dye penetrant for a specified time.

Overview of ASTM F Dye Penetration Integrity Test

Please keep this in mind when developing your studies and validations. If ASTM F testing is used as the quality control method, the test specimen must consist of a complete packaged device.

A dye penetrant solution is applied locally to the seal edge to be tested for leaks. This pressure creates the force needed to rupture the seal. 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. ASTM F procedure requires that the dye penetrant have good contrast to the opaque packaging material. However, since ASTM F testing is designed solely to detect leakage, components that illustrate any indication of leakage are usually rejected.

After contact with the dye penetrant for a specified time, the package is visually inspected for dye penetration.

These leaks are frequently discovered at seals between package components of the same or dissimilar materials. These leaks are frequently found penetratikn seals between package components of the same or dissimilar materials.

It is the responsibility of the pwnetration of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. If wicking does occur, it may be verified by observing the porous side of the subject seal area. In the Burst Testair is introduced into the package at a predetermined pressure and flow rate.

Packaging must be free of condensation or any other source of liquid water. No indication of leak size can be inferred from these tests.

Link to Active This link will always route penstration the current Active version of the standard. They are not quantitative. The Eyedropper method requires the packages to have an unsealed area that extends beyond the outer edge of the seal. There is no general consensus regarding the level of leakage that is likely to be detrimental to a particular package. The test methods are limited to porous materials which can retain the dye penetrant solution and prevent it from discoloring the seal area for a minimum of 5 seconds.

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

The dye will have discolored the surface of the material. 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. The dye solution used in penetration testing will wick through any porous material over time, but normally not within the suggested maximum time. The dye will have discolored the surface of the material.
