1.1These test methods cover the determination of total iron in iron ores, concentrates, and agglomerates in the concentration range 30 % to 95 % iron.
1.2The test methods in this standard are contained in the sections indicated as follows:
| Test Method A— Iron by the Hydrogen Sulfide Reduction Dichromate Titration Method (30 % to 75 % Fe) |
| Test Method B—Iron by the Stannous Chloride Reduction Dichromate Titration Method (35 % to 95 % Fe) |
| Test Method C—Iron by the Silver Reduction Dichromate Titration Method (35 % to 95 % Fe) |
1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Section 5 and in special “Warning” paragraphs throughout these test methods.
1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
