Paper, board, pulps and cellulosic nanomaterials — Determination of dry matter content by oven-drying method — Part 1: Materials in solid form
Abstract

This document specifies an oven-drying method for the determination of the dry matter content in
paper, board, pulp and cellulosic nanomaterials in solid form, which all can be produced from virgin
and /or recycled materials.
It is also applicable to the determination of the dry matter content of paper and board for recycling.
The procedure is applicable to paper, board, and pulp and cellulosic nanomaterials 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 pulp, paper, and board and cellulosic nanomaterial
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.
