GB/T 18829.6-2002 "Determination of Fiber Coarseness" specifies the method for determining fiber coarseness using optical techniques, applicable to various types of papermaking fibers. The width and wall thickness of fibers are measured using a microscope or fiber analyzer, and fiber coarseness (mass/length) is calculated in combination with density parameters. The standard clarifies requirements for sample preparation, measurement points, and data statistics, providing a basis for evaluating fiber characteristics and paper strength performance.
