1 Scope
This document provides guidelines for the laboratory refining of various pulps intended
for paper production including:
-
— Harmonization of terms and parameters for the simulation of industrial refining processes
by laboratory refiners;
-
— Treatment of pulp samples in a (semi) continuous operation in contrast to the batch
operation of laboratory beating equipment such as the PFI mill;
-
— Evaluation of fibres for papermaking, in particular chemical market pulps, under close-to-reality
conditions in terms of refining intensity and refining energy consumption.
This document only considers refiners operating at low stock concentration, i.e. 3 % to 5 %.
