1. Scope
This procedure specifies the method of determining the bending stiffness, also called flexural rigidity, in themachine and cross directions, of corrugated board using four-point loading. The procedure may also be used forsolid boards and paperboard. The method is applicable to boards with a bending stiffness of 0.5 - 200 Nm (4.4 -1770 lbf• in.).
