ActivePaper, board and pulps—Determination of weight factor in fibre furnish analysis
纸、纸板和纸浆 纤维组成分析中质量因子的测定
Application Summary AI generated
This standard specifies the method for determining the weight factor of different fiber types in a fiber furnish analysis, which is used to convert the measured fiber count into the actual mass proportion of each fiber component. It is applied in the quality control and raw material assessment of paper, board, and pulp products, particularly in industries where accurate fiber composition is critical for product performance and cost management. The standard is relevant for testing laboratories and production facilities conducting fiber furnish analysis to ensure consistency and comparability of results.
