Water retention value can be a useful tool in evaluating the performance of pulps relative to dewateringbehavior on the paper machine. The usefulness of the method on a particular application may vary depending ontype of stock, additives, machine configuration and other factors. The method is established to provide standardvalues of centrifugal force, time of centrifuging, and sample preparation so that results can be compared betweeninvestigators at standard values.
