GB/T 22364-2018 《Paper and board—Determination of bending resistance》 Related products

The GB/T 22364-2018 standard defines three methods for measuring the bending stiffness of paper and Cardboard: the constant speed bending method, the Taber Stiffness meter method and the resonance method. The constant speed bending method is suitable for Cardboard in the range of 20 mN to 10,000 mN, the Taber Stiffness meter method is suitable for high-weight Cardboard, and the resonance method is suitable for most paper and Cardboard. The standard clarifies the scope of application of each method and states that the result measurements of different methods are not directly interchangeable, providing detailed guidance for the evaluation of the bending performance of paper and Cardboard.
