ASTM D642

Test Materials: ASTM D642 specifies that the test material is typically packaging containers such as corrugated boxes, plastic containers, or other types of packaging. The material should be in good condition, free from defects, and represent the product’s typical packaging for accurate testing.
Test Process: The top load test involves applying a vertical compressive load to the package. The container is placed on a flat surface, and a load is applied at a consistent rate, typically using a compressive testing machine, until the package collapses or deforms. The maximum load before failure is recorded.
Test Result Interpretation: The test results indicate the maximum load a package can withstand without significant deformation or failure. Higher values suggest better strength and durability of the packaging. Packaging that fails below the expected load indicates potential vulnerabilities in strength or design.
