The method should be used only where other methods, such as automatic sampling of scoop sampling from a free fall, are impossible, or as a reference method.It consists in inserting of two parallel boards or metal sheets vertically down into and at right angles to the streams of the material and to the axis of the stopped belt, and removing of the material between the boards or sheets.
Abstract
Overview
ISO 3963:1977 - "Fertilizers - Sampling from a conveyor by stopping the belt" is a reference method for taking representative samples of solid fertilizers from conveyor belts. Intended for use when automatic sampling or free-fall scoop sampling is impossible, or when a reference procedure is required to validate other sampling techniques, the method involves stopping the belt, inserting two parallel boards or metal sheets across the stream, and removing the material captured between them.
