TAPPI/ANSI T 230 om-13 provides a detailed laboratory procedure for determining the viscosity of 0.5% cellulose pulp solutions using 0.5M cupriethylenediamine and a capillary viscometer. The nine-page official test method covers scope, apparatus, reagents, safety precautions, sampling, specimen preparation, closed-bottle and copper-rod dissolution techniques, viscosity measurement, viscometer cleaning, calculations, reporting, precision, calibration, and preparation and standardization of cupriethylenediamine solution.
This document is intended for pulp, paper, cellulose, and fiber-testing laboratories that evaluate the average degree of polymerization and potential degradation of bleached cotton, wood, and applicable kraft pulps.
Application Scope: Quality control, research, process evaluation, and comparative testing of pulp viscosity using the cupriethylenediamine capillary viscometer method.
