ASTM D3420

Test Materials: ASTM D3420 specifies the use of various materials, primarily flexible packaging substrates such as films and laminates. These materials must be prepared according to standard dimensions to ensure accurate testing results.

Test Process: The test involves subjecting the prepared specimens to a specified force using a controlled apparatus. The procedure includes applying a uniform load to the material until it fails, measuring the force at which this occurs. Proper calibration and environmental controls are crucial for consistency.

Test Result Interpretation: Results are interpreted based on the maximum force required to cause failure in the material. Higher force values indicate better material performance, while lower values suggest potential weaknesses. The data obtained provides insights into the material’s durability and suitability for its intended application.
