1.1This test method covers the determination of titanium in iron ores, concentrates, and agglomerates in the compositional range from 0.01 % to 6.0 % titanium.

Note 1:As used in this test method (except as related to the term relative standard deviation), percent or “%” refers to mass fraction (mas/mass) of the form g/100 g.

1.2Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3This test method has been evaluated in accordance with Practice E1601 and Guide E1763. Unless otherwise noted in Section 13, the lower limit in the scope of each method specifies the lowest analyte content that may be analyzed with acceptable error (defined as a nominal 5 % risk of obtaining a 50 % or larger relative difference in results on the same test sample in two laboratories).

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.

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.
