The necessity for pre-treatment of coal samples prior to equilibration for moisture determination, at 60 per cent. Relative humidity at 40ºC, has been clearly established. If pre-treatment is avoided, the moisture percentages may sometimes be vitiated substantially. Even under extreme conditions of shock drying, pre-treatment maintains its validity in restoring the original desorption path and the moisture values obtained are invariably in line with those expected on fresh coal samples. Since the moisture at 60 per cent. Relative humidity at 40ºC constitutes one of the parameters in rank-classification as also for price-fixation of coals for commercial purposes, the role of pre-treatment in obtaining consistent and reliable moisture values is significant on academic as well as as practical considerations.
