ASTM D642: Standard Test Method for Determining Compressive Resistance of Shipping Containers, Components, and Unit Loads

This test method covers compression tests on shipping containers (for example, boxes and drums) or components, or both. Shipping containers may be tested with or without contents. The procedure may be used for measuring the ability of the container to resist external compressive loads applied to its faces, to diagonally opposite edges, or to corners. This test method covers testing of multiple containers or unit loads, in addition to individual shipping containers, components, materials, or combination thereof.

Box compression tester, as defined by ASTM D642, use to determine if the packaging can endure the pressures of stacking, shipping, and long-term storage.  It main incldue three kinds: 

A, Top-to-bottom compression testing for realistic stacking load conditions.

B, Edge-to-edge and corner-to-corner testing, especially useful for identifying weak points in packaging.

C, Face-to-face compression tests using either fixed or swivel platen machines.

Equipment Required for ASTM D642: 

The compression test machine choice will depend on the maximum specimen size that you need to test.  The size of the test sample will dertermine the vertical test space and the compression platen size. 

Two kinds of the test platen according ASTM D642

1, Fixed type

The upper and lower pressure plates are parallel and fixed in place.

When this type of pressure plate causes damage to the carton, the force is concentrated at the structurally strongest position, which allows for the measurement of the force at the strongest point of strength. 

Can simulate the stress condition when the corners are subjected to force.

2, Free tilting type

One pressure plate is fixed horizontally, while the other can be freely adjusted in all directions.When this type of pressure plate causes carton damage, the force is concentrated at the structurally weakest point, allowing for the measurement of the weakest point's strength.Simulates the real stress situation after stacking cartons.
