Paper, board and pulps - Determination of dry matter content - Oven-drying method (ISO 638:2008); German version EN ISO 638:2008

This International Standard specifies an oven-drying method for the determination of the dry matter content in paper, board and pulp. The procedure is applicable to paper board and pulp which does not contain any appreciable quantities of materials other than water that are volatile at the temperature of (105+/-2) °C. It is used for example, in the case of pulp, paper and board samples taken for chemical and physical tests in the laboratory, when a concurrent determination of dry matter content is required. This method is not applicable to the determination of the dry matter content of slush pulp or to the determination of the saleable mass of pulp lots.
