IS 18657 : Part 2 : 2024/ISO 9276-2 : 2014 Representation of Results of Particle Size Analysis - Part 2 Calculation of Average Particle Sizes/Diameters and Moments from Particle Size Distributions

ICS 19.120

CED 55

NATIONAL FOREWORD

This Indian Standard (Part 2) which is identical to ISO 9276-2 : 2014 'Representation of results of particle size analysis — Part 2: Calculation of average particle sizes/diameters and moments from particle size distributions' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Sieves, Sieving and Other Sizing Methods Sectional Committee and approval of the Civil Engineering Division Council.

This standard is published in various parts. Other parts in this series are:

Part 1 Graphical representation

Part 3 Adjustment of an experimental curve to a reference model

Part 4 Characterization of a classification process

Part 5 Methods of calculation relating to particle size analyses using logarithmic normal probability distribution

Part 6 Descriptive and quantitative representation of particle shape and morphology

The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and

b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
