GB/T 744-2004 "Pulps—Determination of alkali resistance" specifies the method for determining the alkali resistance of pulps, applicable to various types of pulp. The pulp sample is soaked in a sodium hydroxide solution of specified concentration for a specific period, and its alkali resistance is evaluated by measuring the change in viscosity or solubility of the pulp before and after soaking. The standard defines reagent concentration, soaking conditions, and test indicators, providing a basis for evaluating the application performance of pulp in alkaline environments.
