This European Standard specifies a test method for the determination of the dry matter content of a hot- or cold-water extract from paper or board. It is applicable to paper and board intended for boiling or filtering of foodstuffs.
The lower limit determination of the method is about 1000 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 sub-sequent drying of the residue.
