BS EN ISO 638-2:2022 Paper, board, pulps and cellulosic nanomaterials. Determination of dry matter content by oven-drying method. Suspensions of cellulosic nanomaterials
1 Scope
This document specifies an oven-drying method for the determination of the dry matter content in suspensions of cellulosic nanomaterials . The procedure is applicable to cellulosic nanomaterial suspensions which do not contain any appreciable quantities of materials other than water that
are volatile at the temperature of 105 °C ± 2 °C. It is used, for example, in the
case of cellulosic nanomaterial suspensions samples taken for chemical and physical tests in the laboratory, when a concurrent
determination of dry matter content is required.
NOTE This document determines the total dry matter content of the sample, including any dissolved solids. If only the cellulosic material content
free of dissolved solids is desired, dissolved solids are removed prior to measuring
the dry matter content , e.g. by washing or dialysis, taking care to retain all cellulosic material.
