Application Summary AI generated
This standard specifies a method for determining the acid-insoluble ash content in pulp, which measures the residual mineral matter after treating the pulp ash with hydrochloric acid. It is applied in the paper and pulp industry for quality control and raw material evaluation, particularly to assess the presence of silica, sand, or other refractory contaminants in wood or non-wood pulps. The test is critical for ensuring pulp purity and predicting potential processing issues in papermaking equipment.
