| 1 | a) A general clause has been added detailing the guidelines for factors involved. b) Wherever required, the procedures of determinations have been suitably altered, incorporating the repeatability or reproducibility of the elemental analytical values as per the ISO standards. c) Inclusion of the method of calculation of total Iron on the natural, as received basis as a new item as per commercial requirement. d) The procedure for the determination of Sulphur is modified to eliminate the use of MIBK instead of pure Aluminium metal powder has been used to reduce ferric iron to ferrous iron presence of which does not interfere with the accuracy of the method. e) The method of determination of Acid Soluble Iron as per ISO 9035:1989 `Iron ores – Determination of acid-soluble iron (II) content – Titrimetric method’ as it is, included in this revision. f) The method of determination of total iron content-titrimetric methods after titanium (III) chloride reduction as per ISO 2597-2:2019 include | |
