Internal Ply bond Tester TP-J11 is used to test the Z direction tensile internal (interlayer bonding) bonding strength of various paperboards. The instrument design is based on a falling pendulum which creates a high speed impact on a paper specimen. The test paper sample is impacted by certain angle and weight. The energy absorbed by the paper indicates the internal bonding strength of that paper.
A (1 to 6) J indicating error ± 0.05 J
B (1 to 12) J indicating error ± 0.05 J
C (1 to 24) J indicating error ± 0.05 J
D (1 to 48) J indicating error ± 0.05 J
The indicating errors w.r.t measurement range of 20 to 80 %
