摘要
随着国Ⅵ阶段车用汽油标准中组分指标的严格要求,烃类含量限值降低,采用的检测手段更严、检测方法精度更高。文章讨论测定汽油烃类普遍采用的两种方法的影响因素及比较,说明国Ⅵ阶段汽油中测定烃类含量采用GB/T 30519为仲裁方法更为合理。准确测定汽油中烃类含量对产品质量具有很大意义。
With the strict requirements of the component indicators in the national VI phase vehicle gasoline standards,the hydrocarbon content limit is reduced, the detection methods used are more stringent, and the detection methods are more accurate. This article discusses the influencing factors and comparison of the two methods commonly used for the determination of gasoline hydrocarbons, and shows that it is more reasonable to use GB/T 30519 as the arbitration method for the determination of hydrocarbon content in gasoline in the National VI phase. Accurate determination of hydrocarbon content in gasoline is of great significance to product quality.
