ASTM F392

Test Materials
ASTM F392 specifies the use of plastic films and laminates as test materials, focusing on those used in packaging applications. The materials should be prepared to ensure consistent thickness and surface characteristics, which are crucial for reliable test results.

Test Process
The test process involves preparing specimens and conducting peel tests using a controlled testing apparatus. The samples are subjected to a specific peel angle, typically at 90 degrees, ensuring uniform force application until separation occurs. Environmental conditions such as temperature and humidity should be monitored to maintain consistency.

Test Result Interpretation
Results are interpreted based on the maximum force required to peel the samples apart, recorded in pounds per inch. Higher values indicate stronger adhesion, while lower values suggest weaker bonds. The data can be compared against industry standards to assess compliance and performance expectations.
