Paper, board, pulps and cellulose nanomaterials. Determination of residue (ash content) on ignition at 525 °C Ingestion-build-109673 The composition of non-animal hair1 Scope 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.
