This standard specifies the distillation method for distilling stable crude oil to a temperature equivalent to atmospheric pressure of 400°C using a real boiling point distillation apparatus (with 14 to 18 theoretical plates and a reflux ratio of 5:1). This standard applies to crude oil and petroleum mixtures other than liquefied petroleum gas, very light naphtha and petroleum fractions with an initial boiling point above 400°C.
