Foreword

GB/T 22906 "paper core measurement" is divided into nine sections. --- Part 1. sample taken; --- Part 2. temperature and humidity of the treated samples; --- Part 3. Determination of moisture content (oven drying method); --- Part 4. Determination of dimensions; --- Part 5. Determination of characteristics of concentric rotation; --- Part 6. Determination of flexural strength (three-point method); --- Part 7. Determination of modulus of elasticity (three-point method); --- Part 8. Determination of natural frequency and the elastic modulus (experimental modal analysis); --- Part 9. Determination of flat crush strength. This section GB/T Part of 622,906. The partial modification of the use of ISO 11093-6.2005 "Paper and board Determination - Part 6. Determination of three-point bending strength method degree". This part of ISO 11093-6.2005 compared to the main differences are as follows. --- International Standard ISO document standard will be referenced in normative references converted to its corresponding national standard, GB /22906.2 Zhixin Determination T - Part 2. temperature and humidity of the treated samples (GB/T 22906.2-2008, ISO 11093- 2.1994, MOD). This part is proposed by the China National Light Industry Council. This part of the paper by the National Standardization Technical Committee (SAC/TC141) centralized. This section drafted by. China Pulp and Paper Research Institute, China Paper Association Professional Committee of Standardization. The main drafters of this section. Cui Liguo. Determination of paper core Part 6.

3 Terms and Definitions

The following terms and definitions apply to this part of the GB/T 22906 of. 3.1 Under specified conditions, to a sample of a given size to be loaded when bending fracture suffered most vigorously. Principle 4 Core sample material mechanics is regarded as a "beam." During the test, the sample is subjected to a vertical direction in the longitudinal midpoint Force (F), but only at both ends by the support force (see FIG. 1). In order to measure the bending strength, external force is applied until the sample was broken up. F --- the applied force; Determination of length L --- core layer (range). 1 three-point method ......
