The ISO 1762:2019 standard specifies methods for the determination of residues (ash) after burning of paper, Cardboard, pulp and cellulose nanomaterials at 525 ° C. Ash determination is an important quality control indicator in the paper industry, which reflects the content of inorganic components in the sample. This method is suitable for all types of paper, Cardboard, pulp and cellulose nanomaterials, and the ash content is calculated by accurately weighing the mass difference before and after burning of the sample. This standard provides a scientific basis for raw material selection, production process control and product mass evaluation in the paper industry.
