Dewatering properties of pulps Characterisation of pulp slurries often involves measuring the drainage resistance. The most common methods are the Canadian Standard freeness (CSF) according to ISO 5267-2 standard and Schopper-Riegler (SR), ISO 5267-1. Both methods are a relative measure of the drainability of a pulp suspension. CSF measurement involves filtering 1 litre of diluted
