Internal Bond Tester (RL-IBT-A)

This tester is designed to determine the internal bonding strength of paper and paperboard.


The Rycolab RL-IBT-A is used to determine the internal bonding strength of paper according to the Scott Bond method.

This device comes with a built-in digital display and is microprocessor controlled. The standard configuration is delivered with a medium range pendulum. All the parts are built into a sturdy steel frame. A pendulum mechanism pulls the pendulum back to starting position if the test is carried out. Push down sample holder for quick changing of the base plate with the sample and the aluminum angle.

The sample that needs testing is placed in the measuring area. By pushing the start button the pendulum is released and hits the aluminum angle, glued to the sample with double adhesive tape.  The sample is pushed away and the needed energy is measured and displayed in J/m².
