This International Standard specifies a method for the determination of the sulfur content of hydrocarbons such as naphthas, distillates, fuel oils, residues, lubricating base oils only, unleaded gasolines and components. The method is applicable to products having sulfur contents in the range 0,03 % (m/m) to 5 % (m/m).

Samples containing heavy-metal additives, lead alkyls, etc., interfere with the method. Elements such as silicon, phosphorous, calcium, potassium and halides interfere if present in concentrations of more than a few hundred milligrams per kilogram.
