ASTM F 88/F88M : 2021

1.1This test method covers the measurement of the strength of seals in flexible barrier materials.

1.2The test may be conducted on seals between a flexible material and a rigid material.

1.3Seals tested in accordance with this test method may be from any source, laboratory or commercial.

1.4This test method measures the force required to separate a test strip of material containing the seal. It also identifies the mode of specimen failure.

1.5This test method differs from Test Method F2824. Test Method F2824 measures mechanical seal strength while separating an entire lid (cover/membrane) from a rigid or semi-rigid round container.

1.6This test method differs from Test Method F904. Test Method F904 measures the bond strength or ply adhesion of laminates made from flexible materials such as cellulose, paper, plastic film, and foil.

1.7The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.8This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.9This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
