Box Crush Test (BCT) Calculator

Formula

The formula to calculate the Box Crush Test (BCT) is:

\[ BCT = 5.876 \times ECT \times \sqrt{P \times T} \]

Where:

\( BCT \) is the Box Crush Test.
\( ECT \) is the edge crush test.
\( P \) is the box perimeter.
\( T \) is the box thickness.

What is Box Crush Test?

The Box Crush Test (BCT) measures the compressive strength of a box. It is used to determine how much weight a box can withstand before collapsing. This test is crucial for ensuring the durability and reliability of packaging materials.

Example Calculation

Consider an example where:

Edge Crush Test (ECT): 32 lb/in
Box Perimeter (P): 50 inches
Box Thickness (T): 0.25 inches

Using the formula to calculate the Box Crush Test:

\[ BCT = 5.876 \times 32 \times \sqrt{50 \times 0.25} = 665.60 \]

This means that the Box Crush Test value for this example is 665.60.
