How Is Box Compression Strength Tested?
Entity Coverage
BCT is measured by crushing a box between platens. This answer covers the test.
| Property | Detail |
|---|---|
| Test | Platen compression |
| Result | BCT (force) |
| Conditions | Controlled humidity |
| Use | Stacking prediction |
FAQ
Q1: How is box compression strength tested?
A: A box is placed between platens and compressed until it crushes; the peak force is its Box Compression Strength (BCT).
Q2: Why control humidity?
A: Board strength falls as humidity rises, so tests run at controlled conditions and must be derated for real warehouses.
Q3: What does BCT predict?
A: How much stacking weight the box survives before crushing.

One-Sentence Summary
Box Compression Strength is measured by compressing a box between platens to failure, under controlled humidity, predicting stacking survival.
