ASTM E314-16(Test Method)

Standard Test Methods for Determination of Manganese in Iron Ores by Pyrophosphate Potentiometry and Periodate Spectrophotometry Techniques

SIGNIFICANCE AND USE
4.1 This test method is intended to be used for compliance with compositional specifications for manganese content in iron ores, concentrates, and agglomerates. It is assumed that all who use these procedures will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory and that proper waste disposal procedures will be followed. Appropriate quality control practices must be followed such as those described in Guide E882.
SCOPE
1.1 These 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
1.2 Test 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.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This 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 and health practices and determine the applicability of regulatory limitations prior to use.

Iron ores - Wavelength dispersive X-ray fluorescence spectrometers - Determination of precision

ISO/TR 18231:2016 describes methods of test that can be applied to wavelength dispersive X-ray fluorescence (WD-XRF) spectrometers to ensure that the spectrometers are functioning in a manner that allows precise analyses to be made. The tests outlined are designed to measure the errors associated with the operation of certain parts of the spectrometer. They are not designed to check every part of the spectrometer but only those parts that may be the common sources of error. It is assumed that the performance of the instrument has been optimized according to the manufacturer's instructions. For all tests, the two-theta angle should be carefully set for the line being measured. The pulse height window should be set according to the manufacturer's instructions and should have a broad setting which may also include the escape peak for gas proportional counters. The instrument and detector gas environment should be as specified by the manufacturer, as should the power supply to the instrument. NOTE Where no distinction has been made, it is assumed that a test is applicable to both sequential and simultaneous spectrometers.
