ISO 18363-1:2015描述了在碱性催化酯裂解和苯硼酸（PBA）衍生后，间接测定3-MCPD酯（结合3-MCPD）和可能的游离3-MCPD的程序。此外，ISO 18363的这一部分允许间接测定缩水甘油酯（结合缩水甘油），前提是不存在在室温下与无机氯化物反应生成3-MCPD的其他物质。 ISO 18363-1:2015适用于固体和液体脂肪和油。牛奶和奶制品（或来自牛奶和奶制品的脂肪）不在ISO 18363本部分的范围内。

ISO 18363-1:2015 describes a procedure for the indirect determination of 3-MCPD esters (bound 3-MCPD) and possible free 3-MCPD after alkaline catalysed ester cleavage and derivatization with phenylboronic acid (PBA). Furthermore, this part of ISO 18363 enables the indirect determination of glycidyl esters (bound glycidol) under the assumption that no other substances are present that react at room temperature with inorganic chloride to generate 3-MCPD. ISO 18363-1:2015 is applicable to solid and liquid fats and oils. Milk and milk products (or fat coming from milk and milk products) are excluded from the scope of this part of ISO 18363.
