解析GB17930-2016《车用汽油》标准修订内容

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.

Analysis on the revisions of GB 17930-2016"gasoline for motor vehicles" standard

GB 17930-2016 is the standard for China's sixth stage of gasoline for motor vehicles. The new standard redefines the scope of application, adds or deletes some GB or SH standards from the normative references, and revises arbitration test methods for aromatics and olefin contents. The standard adds some technical requirements of gasoline for motor vehicles on the sixth stage, in which aromatics (volume fraction) is decreased from no more than 40% to no more than 35%, VIA stage olefin is decreased from no more than 24% to no more than 18%, VIB is decreased to no more than 15%, benzene content is decreased from no more than 1.0 to no more than 0.8, 50% evaporation temperature is decreased from no higher than 120 °C to no higher than 110 °C. Technical requirements for thiol sulfur is deleted from "gasoline for motor vehicles" standard on the fifth stage. Some of the key technical indicators have reached the current quality requirements of gasoline for motor vehicles in Europe.
