标准范围

本文件描述了纸张、纸板、纸浆和纤维素纳米材料在525°C下着火时残留物（灰分含量）的测定。本文件适用于所有类型的纸张、纸板、纸浆和纤维素纳米材料样品。本文件提供了测量程序，以便在525°C下点火时，残留物（灰分含量）的测量精度达到0.01%或更好。ISO 2144中描述了纸张、纸板、纸浆和纤维素纳米材料在900°C下着火时残留物（灰分含量）的测定。在本文件中，“纤维素纳米材料”一词具体指的是纤维素纳米物体（见3.2至3.4）。由于其纳米尺寸，这些纤维素是纳米的-对象可以具有与纸张、纸板和纸浆相关的固有特性、行为或功能。

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.
