Abstract
What is ISO 638-2 about?
ISO 638-2 specifies an oven-drying method for the determination of the dry matter content in suspensions of cellulosic nanomaterials.
ISO 638-2 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.
ISO 638-2 determines the total dry matter content of the sample, including any dissolved solids. If only the cellulosic material content free of dissolved solid is desired, dissolved solids are removed prior to measuring the dry matter content.
