Scope

This document describes three test methods for determining the bending stiffness of paper and cardboard, which are divided into two-point method, three-point method, and four-point method according to the different loading methods. This document is suitable for determining the bending stiffness of various types of paper and cardboard. Among them, the two-point method and the three-point method are suitable for paper and cardboard with a relatively small thickness, and the four-point method is suitable for corrugated cardboard and cardboard with a relatively large thickness.
