Specifies a method for the determination of the solubility of pulp in cold sodium hydroxide solutions of various and fixed concentrations, being mainly intended for the investigation of bleached pulps. It may, however, also be used with unbleached pulps.
Abstract
Overview
ISO 692:1982 specifies a standardized method for determining the alkali solubility of pulp materials using cold sodium hydroxide (NaOH) solutions at various and fixed concentrations. This test is primarily designed for , but its application extends to as well. The standard focuses on the , which is critical for assessing pulp quality, processing behavior, and performance in paper manufacturing.
