标准范围
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.
