标准范围

ISO 22854:2008规定了测定车用汽油中饱和烃、烯烃和芳香烃的气相色谱(GC)方法。另外，可以测定苯含量、含氧化合物和总含氧化合物含量。ISO 22854:2008适用于芳烃总体积分数高达50%的车用车用汽油；烯烃的总体积分数为约1.5%至多30%；含氧化合物的体积分数为0.8%至15%；约1.5%至约3%的氧的总质量分数；和至多2%的苯的体积分数。尽管该测试方法可用于测定高达50%体积分数的高级烯烃含量，但仅在约1.5%体积分数至约30%体积分数的范围内测试烯烃的精密度。尽管ISO 22854:2008是专门为分析含有含氧化合物的车用汽油而开发的，但也可应用于具有类似沸点范围的其它烃流，例如石脑油和重整物。

ISO 22854:2008 specifies the gas chromatographic (GC) method for the determination of saturated, olefinic and aromatic hydrocarbons in automotive motor gasoline. Additionally, the benzene content, oxygenate compounds and the total oxygenate content can be determined.ISO 22854:2008 is applicable to automotive motor gasoline with a total volume fraction of aromatics of up to 50 %; a total volume fraction of olefins from about 1,5 % up to 30 %; a volume fraction of oxygenates, from 0,8 % up to 15 %; a total mass fraction of oxygen from about 1,5 % to about 3 %; and a volume fraction of benzene of up to 2 %.Although this test method can be used to determine higher-olefin contents of up to 50 % volume fraction, the precision for olefins was tested only in the range from about 1,5 % volume fraction to about 30 % volume fraction.Although specifically developed for the analysis of automotive motor gasoline that contains oxygenates, ISO 22854:2008 can also be applied to other hydrocarbon streams having similar boiling ranges, such as naphthas and reformates.
