ASTM D1922

Test Materials: ASTM D1922 outlines the use of specific samples, typically made from flexible packaging materials, films, and laminates. The materials should be conditioned according to the standard’s requirements to ensure accurate test results.

Test Process: The test involves using a pendulum apparatus to measure the force required to initiate a tear in the sample. The specimen is clamped and subjected to a sharp blade that creates a starter tear. The energy needed to propagate the tear is measured and recorded.

Test Result Interpretation: Results are reported in grams of force required to propagate the tear. Higher values indicate greater resistance to tearing, while lower values suggest more vulnerability. These results help in assessing material performance for packaging applications.
