Scope

This Standard specifies the designations, technical requirements, test methods, packaging,
marking, storage, transport, and quality certificates of silica fume for unshaped refractory.
This Standard applies to that – when smelting ferrous alloys or industrial silicon, silica-
bearing fume are gathered by fume hoods; after oxidized and agglomerated, silica fume is
collected through dry dust collectors.
