标准范围

ISO 4264:2007描述了一种计算石油衍生中间馏分燃料十六烷指数的程序。计算值被称为“四变量方程式十六烷指数”。在ISO 4264:2007的剩余文本中，术语“十六烷指数”通过四变量方程表示十六烷指数。ISO 4264:2007不适用于含有提高十六烷值添加剂的燃料，也不适用于纯碳氢化合物，也不适用于从煤中提取的馏分燃料。适用于含有焦油砂和油页岩非石油衍生物的燃料。

ISO 4264:2007 describes a procedure for the calculation of the cetane index of middle-distillate fuels from petroleum-derived sources. The calculated value is termed the "cetane index by four-variable equation". Throughout the remaining text of ISO 4264:2007, the term "cetane index" implies cetane index by four-variable equation.ISO 4264:2007 is not applicable to fuels containing additives for raising the cetane number, nor to pure hydrocarbons, nor to distillate fuels derived from coal. It is applicable to fuels containing non-petroleum derivatives from tar sand and oil shale.
