Application Summary AI generated

This standard specifies a method for determining the dynamic viscosity number of pulp dissolved in a cupri-ethylenediamine (CED) solution. It is applied in the pulp and paper industry to evaluate the degree of polymerization and degradation of cellulose fibers, particularly for quality control of dissolving pulps used in rayon, cellophane, and cellulose derivative production. The test is conducted in laboratory settings to assess raw material consistency and processing behavior.
