该欧洲标准草案规定了用于测定高达约2毫当量的叔胺氧化物的方法。通过形成酰胺（例如伯胺和仲胺）而失去其与乙酸酐反应的碱性的组分干扰。如果存在，这些伯胺和仲胺必须通过不同的方法来确定，例如与二硫化碳反应

This draft European Standard specifies a method for the determination of up to approximately 2 milli-equivalents of tertiary amine oxide. Components which lose their basicity in reaction with acetic anhydride by forming an amide (e.g. primary and secondary amines) interfere. If present, these primary and secondary amines must be determined by a different procedure e.g. reaction with carbondisulfide.
