Dijind Bubble Leak Testing, Bubble Leak Test Anecto The key difference between the test methods as described in Annex A1 is in allowing time for the water to saturate the porous material. This test method may be used for tray and asfm packages. We, Labthink Instruments Co. This test method may be used to detect substrate holes and channels. Remember me for one month.

These packages will be placed underwater and inflated to a certain pressure. Once that pressure is reached, the package will be observed for a steady stream of bubbles which will indicate that the package has failed. The designated pressure will be determined prior to testing and it is imperative that the pressure be repeatable for multiple accurate tests.

The pressure must not be too high- causing a rupture, or too low. It is recommended that a bleed-off control valve is used to assist in stabilizing pressure. There are two separate test methods depending on if the package is porous or nonporous. This test method provides users with the ability to examine packages for gross leaks. The internal pressurization test is used to evaluate package integrity. Package integrity will benefit the consumer because they can safely receive packages that have been intended to remain sterile or contamination free through heat seal.

There are three 3 apparatus used for ASTM F Pressure Delivery System- the system should have a gage to monitor the pressure, bleed-off control valve. The system should be able to deliver the pressure at mbar. Device for Puncturing Package- this will allow the air source and monitoring device to be inserted into the package Water Container- the container of water must be large enough to cover the entire package with about one 1 inch of water The number of test specimen required for this test is the number that will provide an adequate representation of performance.

There is no conditioning required for this test procedure. Test Method A- Nonporous Packaging: Insert the air source and pressure monitor into the package through a hole.

Seal the hole so that it has minimal air leakage. Then, submerge the package in water and begin inflating the package. The package should remain at least 1 inch under water. In most cases, it is helpful to use some device or fixture to maintain the desired depth of the package throughout the test.

Slowly inflate the package and inspect for a stream of bubbles coming out of the package. Repeat the test on the opposite side of the package. Test Method B- Porous Packaging: Insert the air source and pressure monitor into the package through a hole. Then, submerge the package in at least 1 inch of water and hold for a minimum of 5 seconds.

This will allow the porous package to adjust. Then, begin inflating the package. At the conclusion of testing, the laboratory will compile a comprehensive report that follows the guidelines of ASTM F Keystone Package Testing is proud to provide customers with reliable testing and reports.

More E The evaluation results may be used to assess the likelihood of tube failure during service, a task which is not covered by this practice. Energy flow is perpendicular to lines of magnetic flux. A discontinuity at any point on the through-transmission path can create a perturbation; thus RFT has approximately equal sensitivity to flaws on the inner and outer walls of the tube.

Nejora A stream of bubbles identif i ed at a lower internal pressure than the breathing pressure point may indicate a defect in the packaging. The key difference between the test methods as described in Annex A1 is in allowing time for the water to asrm the porous material. Higher differential pressures will increase the test sensitivity. The compact inspection head is suitable for thermographic ndt tasks. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. The uncooled infrared camera.
