TAPPI T 230 – Viscosity of Pulp (Capillary Viscometer Method)
This method describes a procedure for determining the viscosity of 0.5% cellulose solutions, using 0.5M cupriethylenediamine (CED) as a solvent and a capillary viscometer.Measurements may be made on bleached cotton and wood pulps.Conventional kraft pulps with up to 4% lignin, as defined by TAPPI T222 “Acid-Insoluble Lignin in Wood and Pulp” can also be analyzed.The applicability of this procedure to extended delignification pulps has not been determined.
