The TAPPI T 413 standard specifies a method for the determination of ash content in wood, pulp, paper and Cardboard by the 900 ° C combustion method. This method is suitable for all types of wood, pulp, paper and Cardboard. The percentage of residual ash to the original mass of the sample is calculated by combustion of the sample at 900 ° C to constant weight in a muffle furnace. Ash is the general term for the inorganic components in paper and Cardboard. It is mainly derived from the minerals of the fiber itself and fillers or pigments added during the production process. Ash content has a significant impact on the physical performance (e.g. strength, flexibility) and processing performance (e.g. printability) of paper. This standard provides a standardized ash detection method for the paper industry, which is widely used in quality control, raw material evaluation and product development.
