GB/T 22877-2023 《Paper, board, pulps and cellulose nanomaterials—Determination of residue (ash content) on ignition at 525 °C》 Related products

GB/T 22877 - 2023 is used to determine the residue (ash content) of paper, Cardboard, pulp and cellulose nanomaterials after burning at 525 ° C. The standard specifies the scope of application and covers all kinds of related products. It specifies the collection and prepative process of the sample, and specifies the required equipment. It specifies the operation steps of burning the sample at 525 ° C, as well as the calculation and reporting method of the result. By measuring the ash content, the product mass can be evaluated. This standard provides a unified detection method for related industries, helps to accurately control the quality of products, and promotes the development of industry standardization.
