GB/T 24998-2010 "Paper and board—Determination of alkali reserve" adopts ISO 10716:1994 with modifications, specifying the method for determining the alkali reserve in paper and paperboard. After water extraction of the sample, the alkali reserve is calculated by titration with standard acid. It references standards such as GB/T 450, GB/T 462, and GB/T 601, standardizing the extraction, titration, and calculation processes. This method is used to evaluate the aging resistance and storage stability of paper and paperboard.
