The second part is used to find the ADB analysis. Moisture is also determined in the ADB analysis. (Madb) The ADB analysis is corrected to the field conditions by using the Moisture content in the first sample. The HHV, the proximate analysis and the Ultimate analysis are all corrected by using the same factor.
