> 14989,IS,,ISO 7992:1992,Iron ores — Determination of reduction properties under load,Minerais de fer — Détermination des propriétés de réduction sous charge,1992-08-20,1,['73.060.10'],ISO/TC 102/SC 3,9599,,[38073],"['en','fr']",9,"<p>Specifies a method for evaluating the physical stability of iron ores reduced under load and under specific conditions. The specific conditions are: isothermal heating for reduction, a test portion having a specified size and placed in a fixed bed under load, a reducing gas composed of a carbon monoxide/hydrogen/nitrogen mixture, measurement of the differential gas pressure across a bed of the test portion and measurement of the change in the height of the bed.
