This document describes a method for the determination of the ignition residue (ash) of paper, cardboard, pulp and cellulose nanomaterials at 525°C:
This document is applicable to a variety of paper, board, pulp and cellulose nanomaterials:
Note 1: In this document, the term “cellulose nanomaterials” refers specifically to cellulose nano-objects (see 3:2~3:4): Cellulose nano-objects due to their nanoscale Degree, having inherent properties, characteristics or functions that are different from paper, cardboard and pulp.
Note 2: For the determination method of the ignition residue (ash content) of papermaking raw materials, pulp, paper and cardboard at 900°C, see GB/T 742.
