汽油餾分組成是按照全苏國家標準2177—48(2177—48)(註)進行測定的。分析的準確度即平行测定间的允許誤差,依照全苏國家標準有如下規定:(1)初餾點溫度为4°,(2)終餾點溫度及中間餾分組成點溫度为2°。目前对工廠的要求是不僅所生產汽油的終點要符合全苏國家標準,而且其試樣也要符合於全苏國家標準的嚴格規定,也就是对試樣分析的允許誤差不能作任何的引用。例如,按照全苏國家標準2084—51車用汽油的終餾點应为205°;因
The gasoline fraction composition is determined according to the National Standard 2177-48 (2177-48) (Note). The accuracy of the analysis is the allowable error between parallel determinations. According to the national standard of the whole country, the following provisions are made: (1) Initial boiling point temperature is 4 °; (2) Final boiling point temperature and middle distillate composition point temperature are 2 °. At present, the requirement of the factory is not only that the end point of the gasoline to be produced conforms to the national standards of the whole of Jiangsu, but also that the samples thereof must comply with the strict regulations of the national standards of the whole of Jiangsu, that is, the allowable errors of the sample analysis can not be used for any reference. For example, in accordance with the national standard 2084-51 gasoline end point of gasoline should be 205 °;
