ISO 9276-1.1998 as compared to the main changes are as follows.
--- Change the cover of international standards to meet national standards cover provisions;
--- Normative reference document, with China's national standard instead of the corresponding international standards;
--- "Standard of this section" or the "standard" instead of "this International Standard";
--- Rearrange text page;
--- Remove the relevant ISO international standards of the preamble;
--- Increase the standards described in the preparation of the preamble;
--- Revise international standards introduction;
ISO standards --- references are replaced by the corresponding national standards in force;
--- According to the latest ISO technical errata of the standards were appropriate treatment.

Introduction
It used to describe the universal physical characteristics such as particle size analysis data and terminology, and the cumulative value of a frequency distribution in different
Countries is very different. The reason is because the international standards detailed in favor of consensus and help to transform particle size analysis data.

Particle size analysis results presentation
Part 1. graphical representation
1 Scope
GB/T 15445 in this section is based on the histogram distribution, frequency and cumulative distribution graphs to represent special specification size analysis. Meanwhile Regulation
Set the standard terminology that is determined from the measured data should follow the above distribution.
This section applies to any particle size range of solid particles, liquid droplets or bubbles distributed graphical representation.
Appendix A gives a graphical representation of the results of the analysis of the sample size.
