1 Scope This standard specifies technical requirements, test methods, inspection rules, packaging, storage, transportation, marking and quality certificate of ferrosilicon. This standard is applicable to ferrosilicon usually supplied as deoxidizer or alloy element introducer and magnesium metal for steelmaking and foundry use. 2 Normative References The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.
