Paper, cardboard, pulp and cellulose nanomaterials - Determination of the residue (ash content) after incineration at 525 ° C

The standard describes the determination of the residue (ash content) after incineration at 525 ° C of paper, cardboard, pulp and cellulose nanomaterials. It is applicable to all types of paper, cardboard, pulp and cellulose nanomaterial samples. The standard provides the measurement procedures to obtain a measurement accuracy of 0.01% or better for the residue (ash content) after incineration at 525 ° C. The determination of the residue (ash content) after incineration at 900 ° C of paper, cardboard, pulp and cellulose nanomaterials is described in ISO 2144. In the context of the standard, the term “cellulose nanomaterial” refers specifically to the cellulose nano-object. Due to their size at the nanoscale, these cellulose nano-objects may have inherent characteristics, behaviors or functionalities that are distinct from those associated with paper, board and pulp.
