665.0288 AOCS 7th ed. 2017-2019 rev. Ref.

A homogenized test sample is subjected to centrifuging as specified. The amount of separated material, called sediment (part of the insoluble matter in a crude fat or oil which can be centrifugally separated and is the total amount of the unclear layer of components collected at the bottom of the measuring tube after centrifuging) is volumetrically measured in a calibrated centrifuge tube. This method determines sediment that can be separated from crude fats and oils by centrifugal force. The method is applicable to crude oils and to oils with a sediment content of 0.03 mL per 100 g to 15 mL per 100 g, obtained by means of extraction and/or crushing. The method is not applicable to fats which are not liquid at a temperature of 20 °C. This method is identical to International Organization of Standardization (ISO) 15301.
