Defines a test method to determine the dry matter content of a hot- and cold-water extract from board or paper. The lower limit determination of the method is about 1 000 mg/kg of paper. This corresponds to 1 000 mg/dm2 of a paper with a grammage of 100 g/m2, or 2 000 mg/dm2 for a board with a grammage of 200 g/m2. NOTE:- Some volatile, water-soluble substances may escape during evaporation of the extract and subsequent drying of the residue.
