Scope

This standard specifies the method for the determination of the oxidative stability of
oils and fats under extreme conditions that induce rapid oxidation: high temperature
and high air flow.
This standard applies to unrefined and refined animal and vegetable fats and oils.
This standard is not applicable to the determination of oil stability at room temperature,
but it can be used to compare the efficacy of antioxidants added to oils and fats.
NOTE: The presence of volatile fatty acids and unstable acidic oxidation products affects the accuracy
of the measurement results.

Summary	This standard specifies the high temperature, extreme conditions of high air flow measurement method induced lipid oxidation stability. This standard applies to unrefined and refined animal fat. This standard does not apply to the determination of the stability at room temperature for grease. But can be used to compare the efficiency of the antioxidant added to the oil antioxidants.
