Description
ASTM E314-24 PDF
1.1These test methods cover the determination of manganese in iron ores, concentrates, and agglomerates. The following two test methods are included:
Sections Test Method A (Pyrophosphate (Potentiometric)) 8 – 15 Test Method B (Periodate (Spectrophotometric)) 16 – 22
1.2Test Method A covers the determination of manganese in the range from 2.5 % to 15.0 %. Test Method B covers the determination of manganese in the range of 0.01 % to 5.00 %.
Note 1:The lower limit for this test method is set at 50 % relative error for the lowest grade material tested in the interlaboratory study in accordance with Practice E1601.
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.
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.
