This method provides a means of establishing a line correlation between one of the subsidiary methods of moisture content determination (AS 1289.2.1.2, 2.1.4, 2.1.5 2.1.6) and the standard oven drying method (AS 1289.2.1.1) for a specific soil type. For numerous soils the line of best fit is of the linear type given by this procedure, but for some soils the best relationship can be other than this linear form, in which case this method does not apply.
