Scope

This standard specifies the determination method for measuring the consumption of potassium dichromate under specific conditions by determining the amount of reducing substances dissolved from pulp in a sodium hydroxide solution of a specific concentration (mass fraction of 18%, 10% or other) to reflect the content of organic matter dissolved from pulp in a sodium hydroxide solution of a specific concentration. This standard is applicable to the determination of the alkali solubility of bleached pulp, semi-bleached pulp, and unbleached pulp, and can also be used in research on various stages of bleached pulp production.
