4-Point Bending Stiffness Tester ISO 5628 / DIN 53121
4-Point Bending Stiffness Tester, the bending stiffness is the ratio between the bending moment applied to the standard sample and the defection within the elastic area of the board.
Within the Corrugated Board Industry the Bending stiffness is very important to achieve good stacking and BCT strength. The two biggest influences on Board Stiffness are the tensile strength of the lining paper and corrugated board thickness.
