What are ASTM F1140 and ASTM F2054 about?

ASTM F1140 and ASTM F2054 are both standard test methods related to the integrity and strength of flexible barrier materials used in packaging. Here is a brief overview of each:


  1. ASTM F1140 - Standard Test Methods for Internal Pressurization Failure Resistance of Unrestrained Packages:
    This test method assesses the strength and integrity of the seal of flexible barrier materials such as pouches. The test measures the resistance of a package to rupture when pressurized internally. It is used to evaluate the package's overall strength and the performance of the seals when subjected to an internal pressure differential. There are two distinct methods under ASTM F1140:
    • Method A, the restrained inflation method, where the package is inflated under restraint until a rupture occurs.
    • Method B, the unrestrained inflation method, where the package is freely inflated with air until it bursts.
  2. ASTM F2054 - Standard Test Method for Burst Testing of Flexible Package Seals Using Internal Air Pressurization Within Restraining Plates:
    This standard describes the method for testing the burst strength of seals in flexible packaging that has an area able to be gripped by restraining plates. The restraining plates prevent the expansion of the package during the test, forcing the air to put stress specifically on the package seal until it bursts. This method provides a quantitative measure of the package seal's ability to resist internal pressure and can be used for both quality control and R&D purposes.

Both these tests are used broadly in the packaging industry for quality control, ensuring that packaging meets the necessary standards to protect and maintain the integrity of the contents.

Cell Instruments model LSST-01 Leak and Seal Strength Tester is ideal tool for conducting ASTM F1140 and ASTM F2054 Test.
