BCT Tester: Working Principle, Uses and Applications

As the force increases, the box begins to deform. The operator or machine monitors the specimen until the specified endpoint is reached.

Step 7: Record Maximum Compression Force

The highest compression force reached during the test is recorded. This value provides an indication of the box's compression strength.

Step 8: Examine the Specimen

After the test, inspect the box for buckling, crushing, tearing, corner failure, panel deformation, or complete collapse.

Step 9: Document the Results

Record the test result along with specimen details and testing conditions. Multiple samples may be tested to obtain representative results.

Factors Affecting Box Compression Strength

Several factors can influence the compression strength of a corrugated box. Understanding these factors is important when interpreting BCT results.

Box Dimensions

The length, width, and height of a box can affect its ability to resist compression. Taller boxes may behave differently from shorter boxes under the same loading conditions.
