The TAPPI T 258 standard specifies a method for the measurement of the basic density and Moisture content of pulp wood. The basic density refers to the ratio of the backbone weight to the unit volume of the pulp wood at the maximum volume (green volume), while the Moisture content is calculated by the difference between the original weight of the sample and the weight after drying. This method is suitable for pulp wood in the form of wood chips or discs, and the volume measurement is carried out by soaking and drainage methods to evaluate the mass and processing performance of pulp wood. This standard is widely used in the paper industry and provides an important basis for the procurement, inventory management and processing process optimization of pulp wood.
