Petroleum products. Determination of aromatic hydrocarbon types in middle distillates. High performance liquid chromatography method with refractive index detection1 Scope This document specifies a test method for the determination of the content of mono aromatic, diaromatic and tri+ aromatic hydrocarbons in diesel fuels, paraffinic diesel fuels and petroleum distillates. This document defines two procedures, A and B. Procedure A is applicable to diesel fuels that may contain fatty acid methyl esters (FAME) up to 30 % (V V) (as in [1], [2] or [3]) and petroleum distillates in the boiling range from 150 C to 400
