This International Standard specifies the practical requirements for the taking of a representative sample intended for chemical analysis and measurement of the physical characteristics of aluminium oxide primarily used for the production of aluminium. It applies to aluminium oxide during transport, loading, unloading, continuous flow and storage, as well as to aluminium oxide after storage, for example : — when transported by a conveyor (belt, pipe, slat, etc.); — when stored in, or unloading from, a container, silo or tank, etc; — when in a heap, in a ship's hold, or in open silos, etc. NOTE — This International Standard has been established in the interim period until general methods for the sampling of chemical products, at present under study, have been developed. It will be revised when general methods are available.
