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.
