AS 1141.11.2:2019 PDF
This Standard sets out the method for the determination of particle size distribution in coarse and fine aggregates by vision sizing systems (VSS). The VSS is limited by the discrimination of the optical system and, at present, is suitable for materials coarser than 1.18 mm.
This Standard provides an alternative method to the determination of particle size distribution to the traditional method of sampling production and then sizing using a set of standard sieves (AS 1141.11.1).
With suitable equipment installed, the method allows for sampling, sizing and reporting in a production plant in near to real time.
