GB17930-2016为我国第六阶段车用汽油标准。新标准重新规定了适用范围,增减规范性引用文件中的一些GB和SH标准,修订了芳烃和烯烃含量的仲裁试验方法;增加了第六阶段车用汽油的技术要求,将芳烃(体积分数,下同)由不大于40%降低至不大于35%、ⅥA阶段烯烃由不大于24%分阶段降低至不大于18%、ⅥB阶段降低至不大于15%、苯含量由不大于1.0降低至不大于0.8,将50%蒸发温度由不高于120℃降低至不高于110℃,删除了车用汽油(V)中对硫醇硫的技术要求。一些关键技术指标上已经达到欧洲现阶段或现行车用汽油的质量要求。
GB17930-2016 for the sixth phase of our car gasoline standards. The new standard redefined the scope of application, increasing or decreasing some GB and SH standards in normative references, revising the arbitration test method for aromatic and olefin content; adding the technical requirements for the sixth phase of motor gasoline, adding aromatics (volume fraction , The same below) is reduced from not more than 40% to not more than 35%, the VIA stage olefin is reduced from not more than 24% in stages to not more than 18%, the VIB stage is reduced to not more than 15%, the benzene content is reduced from not more than 1.0 Not more than 0.8, reducing the 50% evaporation temperature from not higher than 120 ° C to not higher than 110 ° C, eliminating the technical requirement for mercaptan sulfur in motor gasoline (V). Some key technical indicators have reached the current European level or the current quality requirements of automotive gasoline.
