本文件规定了测定动植物脂肪和油（以下简称脂肪）碘值（在行业中通常称为IV）的参考方法。 附录B描述了根据脂肪酸组成数据计算IV的方法。这种方法不适用于鱼油。此外，冷压、粗加工和未加工的植物油以及（部分）氢化油通过这两种方法可以得到不同的结果。计算的IV受杂质和热降解产物的影响。 注:附录B中的方法基于AOCS官方方法Cd 1c- 85[10].

This document specifies a reference method for the determination of the iodine value (commonly known in the industry as IV) of animal and vegetable fats and oils, hereinafter referred to as fats. Annex B describes a method for the calculation of the IV from fatty acid compositional data. This method is not applicable to fish oils. Furthermore, cold-pressed, crude and unrefined vegetable oils as well as (partially) hydrogenated oils can give different results by the two methods. The calculated IV is affected by impurities and thermal degradation products. NOTE The method in Annex B is based upon the AOCS Official method Cd 1c-85[10].
