Paper and board — Determination of bending stiffness — General principles for two-point, three-point...
This document specifies three test methods for determining the bending stiffness of paper and paperboard. The test methods differ in the type of loading mode, thus giving rise to the two-point, three-point and four-point bending test methods.
For paper and paperboard in a low thickness range, the two-point bending method and the three-point bending method are suitable.
For corrugated fibreboard…
