Overview

ISO 9276-1:1998, "Representation of results of particle size analysis - Part 1: Graphical representation," defines standardized rules, symbols and plots for presenting particle size distribution data. It covers graphical formats for histograms, density distributions and cumulative distributions for solid particles, droplets or gas bubbles across all size ranges. The standard prescribes a consistent nomenclature (e.g., x or d for particle size, q for density, Q for cumulative) and normalization conventions to ensure unambiguous, comparable visual presentation of particle size analysis results.
