本国际标准规定了挥发性有机污染物的检测和识别方法 在食用油中。 本标准适用于鉴别原油和精制食用油中的挥发性工业化学品 怀疑被污染。它还可以测定污染物的浓度。 本国际标准不适用于测定可能发生反应的化学品的浓度 食用油或其天然成分之一。在这些情况下，污染物的存在可能会 有时可能是建立在定性的基础上。此外，本国际标准不适用于非挥发性物质 化学制品。 该方法已被证明适用于识别以下化合物类别: _饱和卤代烃； _不饱和卤代烃； _酯类；醛类；酒精；胺；酮；以太； _环状和芳香化合物； _氮化合物； _丙烯酸酯；等 该方法的浓度范围为1 mg/kg至10 mg/kg。

This International Standard specifies a method for the detection and identification of a volatile organic contaminant in edible oils. It is applicable to the identification of volatile industrial chemicals in both crude and refined edible oils that are suspected of being contaminated. It also enables determination of the concentration of the contaminant. This International Standard is not applicable to the determination of the concentration of chemicals that may react with the edible oil or with one of its natural components. In these cases, the presence of the contaminant may sometimes be established on a qualitative basis. Also, this International Standard is not applicable to non-volatile chemicals. This method has been shown to be applicable for the identification of the following compound classes: _ saturated halogenated hydrocarbons; _ unsaturated halogenated hydrocarbons; _ esters; aldehydes; alcohols; amines; ketones; ethers; _ cyclic and aromatic compounds; _ nitrogen compounds; _ acrylates; etc. The method has been evaluated for concentrations in the range of 1 mg/kg to 10 mg/kg.
