GB/T 462-2023 "Paper, board and pulps - Determination of moisture content of analytical samples" is applicable to various types of paper, board, and pulps, but not to samples containing volatile substances other than water at 105±2°C. The method employs the oven-drying loss technique, where samples are dried to constant weight at a specified temperature, and the moisture content is calculated based on the mass difference. The standard specifies the requirements for repeatability and reproducibility limits, standardizes sample handling, drying procedures, and the presentation of results.
