GB/T 22364-2018 "Paper and board—Determination of bending stiffness" is applicable to various types of paper and paperboard, specifying the method for determining bending stiffness using the three-point method. It clearly defines terminology, outlines instrument requirements (including the range and accuracy of stiffness testers), standardizes specimen preparation (dimensions, quantity, and conditioning), specifies test procedures (support span, loading speed, test direction), and details the calculation of results. It distinguishes between longitudinal and transverse stiffness testing to ensure the accuracy and comparability of the determination results.
