Paper core/paper tube radial compression testing
Before measuring radial pressure of paper cores/paper tube, prepare a sample with 100mm length paper core/paper tube. Put paper cores/paper tube in the center between two compression platens on the compression testing machine. Load to the paper cores/paper tube at a constant rate of 50-65mm/min. Radial pressure value of paper core/paper tube is maximum force reached firstly or the force value when deformation curve is stable.
