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.

Iron ores — Determination of chromium content — Flame atomic absorption spectrometric method

ISO 15634:2015 specifies a flame atomic absorption spectrometric method for the determination of the chromium content of iron ores. This method is applicable to chromium contents between 0,001 6 % and 0,1 % (mass fractions) in natural iron ores, iron ore concentrates, and agglomerates including sinter products.

Iron ores — Determination of loss on ignition — Gravimetric method

ISO 11536:2015 specifies a gravimetric method for the determination of the loss in mass of fully-oxidized iron ores, when ignited at 1 000 °C. This method is applicable to a concentration range of 1,0 % (m/m) to 10,0 % (m/m) loss on ignition in natural iron ores, iron ore concentrates and agglomerates. The method is not applicable to the following: a) Processed ores containing metallic iron (direct reduced iron); b) Natural or processed ores in which the sulfur content is higher than 0,2 % (m/m); c) Natural or processed ores in which the content of partially-oxidized iron is more than 1,0 % (m/m).

Iron ores — Sampling of slurries

ISO 16742:2014 sets out the basic methods for sampling fine iron ore of nominal top size The procedures described in ISO 16742:2014 apply to sampling of iron ore that is transported in moving streams as a slurry. These streams can fall freely or be confined in pipes, launders, chutes, spirals, or similar channels.
