Standard Title
Compression Test of Fiberboard Shipping Containers, Test Method
Overview for TAPPI T804 Shipping Container Compression Test:
TAPPI T804 Test Method measures the compressive resistance ability of corrugated shipping containers and can be evaluated in various orientations and configurations. The ability to confirm if a box will meet the intended compression resistance needed is essential during box design. The TAPPI T804 standard is used to measure the resistance of shipping containers to compressive forces during handling, transportation, and storage. This test involves placing a shipping container on a rigid flat surface and applying a load at a steady rate until the container collapses or reaches a specified deformation limit.
Â
The TAPPI T804 standard specifies the test procedure, equipment, and conditions necessary for conducting a reliable and reproducible compression test on shipping containers. The test equipment typically includes a compression testing machine, a load cell, a sample holder, and a deformeter to measure the deformation of the container.
Â
During the test, the container is loaded vertically with a defined maximum load capacity, and the load is maintained for a specified time to test the container’s resistance to compression. The compression force is gradually increased until the container begins to deform, and the deformation is recorded continuously.
Â
The TAPPI T804 test is used to evaluate the performance of shipping containers during transportation, storage, and handling and to ensure that the container can withstand a range of compression forces that it might encounter in real-world conditions. The test results can help manufacturers optimize their container design and materials and improve the overall safety and efficiency of the shipping process. Purple Diamond Testing offers TAPPI T804 Compression Test of Fiberboard Shipping Containers as part of our packaging compliance and validation services.
Rationale for TAPPI T804 Shipping Container Compression Test:
This test method is useful in finding the shipper’s max compression resistance. By evaluating it empty and by evaluating it full, the amount of load share expected from the inner contents can be calculated. In addition, by rotating the sample on its side or end, the max compression resistance can be obtained for these orientations, which simulates clamping forces. It is also possible to evaluate how the corrugated reacts to different environmental conditions, such as high humidity exposure.
Key Points:
- Confirms material selection will meet compression resistance requirements during box design
- Optimize costs by mitigating damages accrued through transit
- Verifies corrugated shipping container performance under compression
- Verifies percent load share of inner contents
