标准范围

本文件规定了重力沉降粒度分析的原理、测量技术的主要类型以及进行测量、方法验证、不确定度预算的确定和结果表示的一般规则。本文件既不包括离心力、电力或磁力引起的颗粒迁移，也不包括高颗粒浓度下的沉降（例如区域沉降）。此外，该文献不涉及除沉降速度和粒度之外的性质的测定（即，既不涉及颗粒浓度、颗粒形状、颗粒密度、ζ电位也不涉及表观粘度）。笔记？本文件可能涉及危险材料、操作和设备。本文件并不旨在解决与其使用相关的所有安全问题。检查低闪点挥发性液体时，需要防爆分析仪。

This document specifies the principles of particle size analysis by gravitational sedimentation, the principal types of measurement techniques as well as the general rules for conducting measurements, method validation, determination of the uncertainty budget and representation of results.

This document covers neither particle migration by centrifugal, electric or magnetic forces nor sedimentation at high particle concentrations (e.g. zone sedimentation). Moreover, this document does not deal with the determination of properties other than sedimentation velocity and particle size (i.e. neither particle concentration, particle shape, particle density, zeta-potential nor apparent viscosity).

NOTE            This document can involve hazardous materials, operations and equipment. This document does not purport to address all the safety problems associated with its use. Explosion proof analysers are required when examining volatile liquids with a low flash point.
