Paper, cardboard, pulp and cellulosic nanomaterials - Test method for residue (ash content) at an ashes of 900 ° C (ISO 2144: 2019, IDT)

This document describes how to test the ash content of paper, cardboard, pulp and cellulose nanomaterials. This document applies to all types of paper, cardboard, pulp and cellulosic nanomaterials. This document presents a measurement procedure for obtaining a measurement precision of 0.01% or better for a residue (ash content) at 900 ° C. In the context of this document, the term "cellulosic nanomaterials" refers specifically to cellulose nano-objects (see 3.2 to 3.4). Due to their nanometer-scale dimensions, these cellulose nano-objects can have different intrinsic properties, behavior or functions than those associated with paper, cardboard and pulp.
