Box compression test (BCT): BCT is the load a box can bear before it buckles. It is the most useful single number for how high boxes can be stacked.
In more detail
A box is compressed between plates until it fails. Stacking time, humidity and handling reduce real-world strength, so a safety factor is applied.
Why it matters
Use BCT to agree performance with your box supplier instead of only listing grades.
How it is measured or specified
Measured on a compression tester; agree the conditioning and method.
