Standard Representation of results of particle size analysis Part 2: Calculation of average particle sizes diameters and moments from particle size distributions ISO 9276-2:2001 Swedish Institute for Standards, SIS

For both notation systems, numerical examples of the calculation of mean particle sizes and standard deviation from histogram data are presented in an annex. The standard’s annexes give numerical illustrations of how to compute mean particle sizes and standard deviations using histogram data. It does, however, issue a warning that if the distribution is insufficient or only a small number of size classes are used, the accuracy of the mean particle size may be jeopardized. The size distribution may be available as a histogram or as an analytical function.

The equivalent diameter of a particle of any shape is taken as the size of that particle.
Samples of particles measured are intended to be representative of the population of particles.
