Anotácia

Description / Abstract: ISO 2496:2006 specifies the following four test methods for the determination of the hygroscopic moisture content of test samples: Method 1 -- Gravimetric method; Method 2 -- Karl Fischer volumetric method; Method 3 -- Karl Fischer coulometric method; Method 4 -- Mass-loss method. Any of these methods is applicable wherever the analytical value of a chemical constituent is to be calculated to a dried sample basis in the following ore types. Processed ores containing metallic iron (direct reduced iron).Natural or processed ores in which the sulfur content is greater than 0,2 % (mass fraction).Natural or processed ores in which the combined water is greater than 2,5 % (mass fraction). Any of these methods is applicable to a concentration range of 0,05 % (mass fraction) to 4,5 % (mass fraction) hygroscopic moisture.
