Järnmalm - Bestämning av halt syralösligt järn(II) - Titreringsmetod (ISO 9035, IDT)

Status: Gällande

This International Standard specifies a method for the determi­nation of iron(II) content in natural and processed iron ores containing from 1 % to 25 % acid-soluble iron(II) and only tra­ces of metallic iron. This method is specifically limited for use in conjunction with the reducibility test methods specified in ISO 4695 or ISO 7215. This method is not applicable to ores containing more than 0,3 % (m/m) sulfur (as sulfide) and/or 5 % (m/m) free carbon. Experiments have shown that the acid-insoluble residue can be neglected, especially as regards the needs of the reducibility test methods concerned and the precision obtainable.
