ASTM F2096 Gross Leaks in Packaging by Internal Pressurization

ASTM F2096 detects gross leaks in tray and pouch packages. As an ISTA and ISO 17025 certified lab, we realize the importance of internal pressurization testing. Meeting the ASTM F2096 requirements can be difficult. We understand the challenges and guide companies through the process.

We are in constant communication throughout the test process. Keystone Package Testing creates an accurate test plan to eliminate expensive over-testing. Our pricing is competitive and we offer volume discounts. Keystone’s proven process helps avoid product launch delays. Lastly, when packages do not meet the requirements, we assist with finding solutions.

Summary of ASTM F2096 Bubble Test Information

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.

Scope of ASTM Packaging by Internal Pressurization Testing

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 F2096

    1. 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 0-50 mbar.
    2. Device for Puncturing Package- this will allow the air source and monitoring device to be inserted into the package
    3. 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 specimens 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. Seal the hole so that it has minimal air leakage. 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.

Like test method A, The package should remain at least 1 inch under water. 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.
