scope:

This European Standard specifies the gas chromatography determination of saturated, olefinic and aromatic hydrocarbons in finished petrol according to EN 228. Additionally, the benzene content, oxygenate compounds and the total oxygenate content can be determined. The method is applicable for finished petrol with total aromatic content up to 50 % (V/V), total olefin content from about 1,5 % (V/V) up to 30 % (V/V), oxygenate compounds up to 15 % (V/V), total oxygen content from about 1,5 % (m/m) to about 3 % (m/m) and benzene content less than 2 % (V/V).
