This specification covers standard methods for sampling and testing of various ferroalloys for size analysis. Ferroalloys are classified into lump and crushed or plates sizes. The small-sized samples subject to screen testing shall be taken from the lot sample by riffling, and larger sized samples by mixing and quartering. Sizing of lumps shall be done by visual examination. Crushed or plates materials shall be subjected to sieving by using either manually driven or mechanically driven screen vibrators to divide samples into several size fractions.
