Tiêu chuẩn ASTMD4577
Test Materials: The ASTM D4577 top load test is typically conducted on packaging materials such as plastic, glass, and metal containers, including bottles and jars. These containers are filled with a standard product to simulate actual conditions during transport and storage.
Test Process: The test involves applying a compressive force to the container in a controlled manner until it deforms or fails. The load is applied gradually to determine the maximum strength the container can withstand without damage.
Test Result Interpretation: Results are interpreted by measuring the force at which the container begins to show signs of failure or permanent deformation. The higher the force threshold, the better the packaging material’s ability to withstand stacking or shipping pressures without compromising its integrity.
