This procedure is used to define the papermaking quality of pulp, by subjecting it to a controlled mechanical treatment in a laboratory beater; see also TAPPI T 248 Laboratory Beating of Pulp (PFI Mill Method).
The beating procedure may be used with any pulp, suitably modifying the withdrawal schedule to provide the number of samples required for a satisfactory beater curve. The method may not give satisfactory results with certain extremely long-fibered pulps, such as cotton fibers or jute since the fibers entangle and tend to rope in the beater.
