This International Standard specifies three methods
(two titrimetric and one potentiometric) for the de-
termination of acidity in animal and vegetable fats and
oils, hereinafter referred to as fats. The acidity is ex-
pressed preferably as acid value, or alternatively as
acidity calculated conventionally.
The method described in clause 4 is the reference
method. The method described in clause 5 applies to
oils and fats which are not strongly coloured.
The methods are riot applicable to waxes.
