Leak Testing Standard: Bubble Leak Test

Test Theory and Process Overview

ཚིག༌ཕྲད ཨེ་ཨེསི་ཊི་ཨེམ་ཨེཕ་༢༠༩༦ test is designed to detect gross leaks by using pressurized air and water immersion. Flexible packages are internally pressurized, and the entire system is submerged in water. The fundamental principle behind the test is simple: when the package is pressurized, any defects or gross leaks will allow air to escape, producing visible bubbles in the water. This visual confirmation of a leak is highly reliable for gross leaks, ensuring packages meet required integrity standards.

Sensitivity, Application and Nature

The method can detect leaks as small as 250 microns, making it effective for ensuring that packaging retains its necessary airtight properties. Importantly, ཨེ་ཨེསི་ཊི་ཨེམ་ཨེཕ་༢༠༩༦ is applicable to a wide range of flexible packaging materials, including porous and non-porous materials. 

The sensitivity of this test method is dependent on the differential pressure and method of pressurization.

The package is inflated underwater to a predetermined pressure. The package is then observed for a steady stream of air bubbles indicating a failure area.

ASTM F2096 Test Method A—Procedure for Nonporous Packaging

  • 1. Preparation: Create a hole in the package using a puncturing device for inserting the air source and pressure monitor link into the control sample. Use tape or a rubber disk as a septum over the puncture site to seal the insertion site if necessary.
  • 2. Inflation: Submerge the package approximately 1 in. under water. Start airflow into the package. Adjust the airflow to slowly inflate the package to a value equal to or greater than the minimum test pressure and then maintain it as constant pressure.
  • 3. Inspection: Thoroughly inspect one side of the package facing upwards for a constant stream of bubbles indicating a specific area of failure (seal channels, pinholes, cracks, tears, and so forth). Then repeat the process by rotating the package 180º so the opposite side of the package is facing upwards. Inspection time will vary depending on package size.
  • 4. Mark: Remove the package from water and mark any observed area(s) of failure.

ASTM F2096 Test Method B—Procedure for Porous Packaging

Method B is basically the same process as Method A, except it has one more step for treating the porous packaging sample. As porous material may begin to breathe prior to observing the defect, apply a blocking agent 5 to the porous material and repeat above test step.  

The intent of the blocking agent is to reduce the porosity of the porous material, therefore, increasing the internal test pressure. However, the blocking agent may have a profound effect on both the physical and chemical nature of the porous packaging material and may therefore give a wide range of breathing point pressures. It is recommended to use the minimal quantity of blocking agent necessary to detect the known defect.

Significance of ASTM F2096

In industries such as pharmaceuticals, medical devices, and food packaging, even a small packaging defect can have significant consequences. The ability to ensure package integrity is therefore crucial, and ཨེ་ཨེསི་ཊི་ཨེམ་ཨེཕ་༢༠༩༦ offers a reliable, cost-effective solution for detecting gross leaks. This method helps manufacturers maintain quality control standards and ensures that the packaging can protect the product from environmental contaminants, spoilage, and sterility breaches.

The test is particularly useful for verifying the sterility of medical devices and the preservation of pharmaceutical products, where the smallest contamination could lead to catastrophic results.

Advantages of ASTM F2096

Practical Testing

The ASTM F2096 internal pressurization test method provides a practical way to examine packages for gross leaks.

Large and Long Sample Applicable

ASTM F2096 test method applies to very large or long packages, which do not fit into any other package integrity test method apparatus.

Package Integrity Evaluation

Package integrity is crucial to consumer safety since heat sealed packages are designed to provide a contamination free and sterile environment to the product.

Equipment and Technology for ASTM F2096 Compliance

To effectively perform ASTM F2096 Bubble Leak Testing, specialized equipment is essential. High-precision tools that can maintain and control pressure increments, as well as large water-filled chambers, are required. A complete leak testing setup typically includes:

  1. Pressure Delivery System: A controlled air supply system capable of delivering air pressure to the package accurately.
  2. Water Immersion Tank: A chamber large enough to accommodate the full package, filled with water for submersion.
  3. Pressure Gauge or pressure transducer: A highly accurate gauge or transducer to monitor and control the air pressure applied to the package.
  4. Sealing and Puncture Devices: To introduce air into the package without compromising the seal.
