Packaging should meet the American Society for Testing and Materials (ASTM) standards for the product line. Burst tests, edge crush tests, and tear tests also provide guidelines for product selection. Corner board product size, thickness, material, and angle should, then, match the product need and the container quality.

L&W Crush Tester tests corrugated board, liner and fluting as well as performing compression tests on small boxes. The instrument measures new crush properties such as flat crush hardness and the total energy absorbed during a FCT measurement. A built-in plate distance sensor can also be used to measure the corrugated board thickness. Benefits

The edge crush test is a laboratory test method that is used to measure the cross-direction crushing of a sample of corrugated board.It gives information on the ability of a particular board construction to resist crushing. It provides some relationship with the peak top-to-bottom compression strength of empty singlewall regular slotted containers in laboratory conditions.

Edge crush test, right test, or flat crush test helps determine this. In the Edge Crush test, force is applied to one side of the box, perpendicular to the ridges, until the box gets crushed. In the Ring Crush test, a ring cut out from the box is used to test the same. While in the flat crush test, excessive force is applied on one side.
