The torque is measured and recorded throughout a special mixing process: the oil is continuously added by an automated buret into the mixer. The free flowing, powdery material absorbs the liquid. This leads to agglomerate formation until saturation. During this transition, more and more torque is needed for the mixing and eventually a torque peak appears on the time-torque curve. The OAN itself is given in accordance with the standards and common practice in ml (of the absorbed oil) / 100 g (of sample material).
