1 Scope This standard specifies methods for the determination of acidity of animal and vegetable fats and oils (two titrimetric and one potentiometric) for the determination of acidity in animal and vegetable fats and oils. The acidity is expressed preferably as acid value. The hot ethanol determination method is the reference method. The cold solvent method described is applicable to light-color fats and oils. The methods are not applicable to waxes. 2 Normative References The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments to (excluding amending errors in the text), or revisions of, any of these publications do not apply. However, all parties coming to an agreement according to this standard are encouraged to study whether the latest edition of the normative document is applicable. For undated references, the latest edition of the normative document applies.
