GB/T 24447-2009 "Pulp—Determination of coarseness by polarized light method" specifies the use of the polarized light method for determining the coarseness of pulp fibers. It is applicable to all types of pulp that can polarize light, with the measurement results excluding fibers shorter than 0.2 mm. The standard employs an automatic optical analyzer to test pulp samples, standardizes instrument parameter settings and result calculation methods, and accurately reflects the thickness of pulp fibers.
