Carbonaceous materials used in the production of aluminium. Calcined coke. Determination of particle size distribution Ingestion-build-52208 BS EN 1990 describes the1 Scope This document specifies a method for the determination of the particle size distribution of a sample of coke having a typical size distribution as normally produced by calcination of delayed petroleum coke. The same procedure is applicable to consignments of calcined anthracite. This document does not apply to fractions of carbon material prepared by sieving and crushing or to filter fines. This method is applicable to the determination of
