TAPPI T 254 CM 2010

TAPPI T 254 cm-10 is a technical PDF test method for measuring the cupriethylenediamine disperse viscosity of pulp using the falling ball method.

TAPPI T 254 cm-10 provides a complete laboratory procedure for measuring the viscosity of 1% cellulose solutions in cupriethylenediamine using a calibrated falling ball viscometer. The 10-page PDF covers scope, significance, required apparatus and reagents, chemical safety, pulp sampling and specimen preparation, viscosity tube calibration, CED solution preparation and standardization, testing procedures, calculations, reporting requirements, precision data, related methods, and an appendix for preparing cupriethylenediamine solvent. It is intended for technical, laboratory, quality-control, and research personnel working with bleached, unbleached, and high-yield pulps.

Application Scope: Suitable for pulp and cellulose laboratories, production control, process monitoring, quality assurance, and research applications requiring falling-ball cupriethylenediamine viscosity measurements.
