"GB/T 7978 - 2005 Pulp, Determination of acid-insoluble ash" specifies the determination method of acid-insoluble ash in pulp. The standard specifies the test principle, equipment, reagent requirements and operation procedures, and separates and determines the content of acid-insoluble inorganic components by acid-treating pulp samples. The standard provides a scientific basis for evaluating pulp purity, mass monitoring and process optimization, and helps to accurately control the acid-insoluble ash index in pulp and ensure the stable performance of pulp products.
