ASTM F1140: Burst and Creep Package Compliance Testing

ASTM F1140 package testing explains the procedure for determining the ability of packages to withstand internal pressurization. As an ISTA and ISO 17025 certified lab, we realize the importance of internal pressurization testing. Meeting the requirements of ASTM F1140 burst and creep testing can be difficult. We understand the challenges and guide companies through the process.

Keystone Package Testing’s proven process helps avoid product launch delays. Thus, we provide the peace of mind that all of your needs will be met. Our accurate test reports are delivered quickly. Lastly, Keystone offers competitive pricing and volume discounts.

Summary of Flexible Package Testing Information

ASTM F1140 package testing covers the ability of a flexible package to withstand internal pressurization. This test procedure is also known as package integrity testing or leak testing. Additionally, the test standard provides insight on package failures from a pressure differential. 

These differentials often occur during sterilization and transportation. ASTM F1140 is often required for medical packages. Many food packages undergo this testing as well.

Scope of ASTM F1140 Burst and Creep Shock Testing

Package evaluation can occur during the package’s life cycle. This helps find failures in the lab instead of in the field. ASTM F-1140 package testing must consider many factors. These include but are not limited to package size, material, and sensitivity. 

Other factors include seal configuration, sensitivity, and rate of airflow into the package. There are two types of testing. First, there is burst testing. Second, there is creep testing.

ASTM F1140 Burst and Creep Lab Testing Procedures

Burst Testing

Burst testing involves pressurizing a package until it fails. The internal pressurization is increased during testing. The test measure is the maximum pressure detected before the package fails. The failure is a visible observation. The type of failure must be noted. It could be a seal failure or packaging material failure.

ASTM F1140 may be tested with or without the packaged product. Furthermore, it may be tested either open or closed.

Creep Testing

Creep testing maintains a set pressure for a specific time. The testing can also result in failure. The test measure is pass or fail. The starting pressure is a percentage of the burst pressure. The typical starting point is 80%. This value may be raised or lowered as needed.

Like burst integrity testing, creep testing can be with or without the product enclosed. During inflation, the seal is observed. Deformations or seal breaks are noted. The test is complete once a set time is reached or the package fails.

In creep to failure package testing, packages are creep tested and held until they fail. The test setup is similar to creep testing. The pressure setting is higher to ensure failure in a reasonable matter of time. The test measure is the amount of time until failure. A typical starting pressure is 90% of the package burst value.

Significance of ASTM F1140 Creep and Burst Integrity Testing

After ASTM F1140 burst and creep compliance, Keystone Package Testing provides a test report. This report will include the following information:

  • Test procedure.
  • Details of the machine.
  • Position of the package.
  • Blocking agent flow-limiting method.
  • Type of material used.
  • Number of packages tested.
  • Number of failures.
  • Any conditioning before testing.

The report will state general information such as the date, time, location, and test engineer.

For the burst test, the burst pressure value and location of the failure are included. For creep testing, the internal pressure and hold time are noted. For creep to failure testing, the internal pressure and hold time are included.

Expert Pressurization Failure Resistance Package Testing

Keystone strives to give our customers more time and energy on product development instead of testing. We can accommodate flexible and rigid packages of all sizes, including large pallets. In addition to ASTM flexible package testing, Keystone has a full scope of expertise including drop, leak penetration, and accelerated aging.
