The method consists in passaging of the material through a rotating sample divider and collecting of the fractions, followed by rejection or recombination of some of the fractions. By choosing suitable equipment it is applicable to any mass above a minimum defined by size and number of particles.
Abstract
Overview
ISO 7742:1988 - "Solid fertilizers - Reduction of samples" specifies a reproducible method for reducing a bulk sample of solid fertilizer to a smaller, representative portion for analysis or further reduction. The method is based on passing material through a rotating sample divider, collecting fractions and then rejecting or recombining selected fractions. By choosing suitable equipment the procedure is applicable to any mass above the minimum defined by particle size and particle count.
