GB/T 29775-2013 "Pulp—Determination of fiber coarseness—Image analysis method" specifies the image analysis method for determining the fiber coarseness of pulp, applicable to all types of pulp. The pulp sample is dispersed to form a suspension, and fiber images are captured using an image analyzer. With the aid of software, parameters such as fiber diameter and cross-sectional area are measured to calculate the fiber coarseness value. The standard specifies requirements for sample preparation, dispersion conditions, instrument calibration, and parameter settings. At least 200 valid fibers must be tested, and the results are averaged to ensure the accuracy of fiber coarseness determination.
