GB/T 37858-2019 "Pulp—Determination of Wet Weight of Fibers" is applicable to all types of pulp. It specifies the process for determining the wet weight of pulp fibers. Pulp sheet samples require soaking and disintegration treatment, while wet pulp samples need to be diluted to a specific concentration. Fibers are separated and collected using relevant instruments, with clear requirements for sampling, sample preparation, and testing procedures to ensure the reliability of the wet weight measurement results.
