This standard specifies the method for determining the copper price in bleached chemical pulps and dissolved pulps, but does not apply to mechanical pulps or unbleached pulps. The copper price is an indicator to measure the content of reducing substances (such as oxidized cellulose, hydrolysis cellulose, lignin and sugar, etc.) in pulp. The copper price determination can evaluate the degree of degradation and deterioration of cellulose. This standard provides scientific analysis means for the pulp industry to ensure the conformity and Stability of pulp mass. It is one of the important methods in pulp quality control.
