BCT Tester: Working Principle, Uses and Applications

Select the corrugated box or packaging sample to be tested. The specimen should represent the actual production packaging as closely as possible.

Record relevant details such as box dimensions, board construction, flute type, and sample identification.

Step 2: Inspect the Box

Before testing, inspect the specimen for visible damage, moisture, manufacturing defects, crushed edges, or other conditions that may affect the result.

Step 3: Position the Box

Place the box centrally on the lower compression plate. The box should be positioned according to the required test orientation.

Correct positioning is important because an improperly aligned specimen may produce inconsistent or misleading results.

Step 4: Set Test Parameters

Enter the required test parameters through the machine's control system. Depending on the equipment and standard, these may include compression speed, test mode, and stopping conditions.

Step 5: Start Compression

The upper plate moves downward and gradually applies compression to the box. The load cell continuously measures the force applied during the test.

Step 6: Observe Box Deformation
