Compression test of fiberboard shipping containers |
TAPPI T 804 Compression method is used for measuring the ability of corrugated or solid fiber shipping containers to resist external compressive forces. The method may be applied in a number of ways. For quality studies, it is usually desirable to test the empty container. For the study of compression resistance where inner packing (corner posts, etc.) is involved, tests may be made with the interior packing in place. If overall performance of the entire pack is to be studied, the test may be conducted with the container loaded with its contents and all inner packing. In many packs the contents and inner packing share in carrying a portion of the load. The container may be positioned in the machine so as to test the compressive resistance in a direction that is relevant to the container’s use including top-to-bottom, end-to-end, or side-to-side.
In essence this method describes how to determine the resistance of a fiberboard shipping container to compressive forces. This is accomplished by placing the container between two flat platens, one of which is mechanically or hydraulically driven to compress the container. A recording device is incorporated to indicate the force and deformation (deflection) required to compress the container.
These compressive forces are related to some of those exerted on containers in stacks or encountered in transportation. The method may be used to compare the compressive resistance of different lots of similar containers or to compare containers of different grades. It may also be used to compare the compression characteristics of containers differing in construction or design. In addition, the information gained may be used to provide an indication of the load that a particular container may be able to withstand in service.
Boxes need to have dimensions smaller than 5.5 inches to allow us to compress it in all directions.
