Application Summary AI generated

This standard specifies the PFI mill method for laboratory beating of pulps, used to simulate the mechanical refining process that occurs in paper mills. It is applied in the pulp and paper industry for quality control, research, and development to evaluate how different pulp types respond to refining and to predict their behavior during papermaking. The method is essential for standardizing test conditions across laboratories to ensure reproducible results for fiber property assessments.
