M02.005 Determination of the loss of ignitation of dry mass at 550°C

This method describes the determination of the loss of ignition (LOI) or the residue of ignition, respectively, of dry mass at 550°C. The LOI can be calculated from the difference of masses before and after the annealing process. The dry matter has been determined in accordance with method M02.008. The LOI or the residue of ignition is reported as percent of dry mass.
