Proposes the adoption of ISO 9276-2:2001 as an Australian Standard. ISO 9276-2 provides the relevant equations for the calculation of average particle sizes or average particle diameters from a given particle size distribution. It is assumed that the size distribution is available as a histogram (see normative reference). The same mathematical treatment can, however, also be applied, if the size distribution is represented by an analytical function. It is furthermore assumed in the following chapters that the size X of a particle is described diameter of a particle or any other shape by the diameter of a sphere. Depending on the problem size, X, may however also represent an equivalent diameter of a particle of any other shape. Copies of ISO 9276-2 may be purchased from or viewed at Standards Australia Offices.
