適用范圍：This International Standard specifies three methods (two titrimetric and one potentiometric) for thedetermination of the acidity in animal and vegetable fats and oils, hereinafter referred to as fats, The acidity isexpressed preferably as acid value, or alternatively as acidity calculated conventionallyThis International Standard is applicable to refined and crude vegetable or animal fats and oils, soap stockfatty acids or technical fatty acids. The methods are not applicable to waxes.Since the methods are completely non-specific, they cannot be used to differentiate between mineral acids.free fatty acids, and other organic acids. The acid value, therefore, also includes any mineral acids that maybe present.
