This document describes the determination of the residue (ash content) on ignition of paper, board, pulps and cellulose nanomaterials at 525 °C. It is applicable to all types of paper, board, pulp and cellulose nanomaterial samples. This document provides measurement procedures to obtain a measurement precision of 0,01 % or better for residue (ash content) on ignition at 525 °C. Determination of residue (ash content) on ignition at 900 °C of paper, board, pulps and cellulose nanomaterials is described in ISO 2144. In the context of this document, the term “cellulose nanomaterial” refers specifically to cellulose nano- object (see 3.2 to 3.4). Owing to their nanoscale dimensions, these cellulose nano-objects can have intrinsic properties, behaviours or functionalities that are distinct from those associated with paper, board and pulps.
