This International Standard specifies a method for the determination of the insoluble impurities content of
animal and vegetable fats and oils.
If it is not desired to include soaps (particularly calcium soaps) or oxidized fatty acids in the insoluble
impurities content, it is necessary to use a different solvent and procedure. In this case, an agreement is to be
reached between the parties concerned.
