Standard Test Method for Sulfur in Petroleum Products (High-Temperature Method)
|Publication Date:||31 August 1979|
|ICS Code (Petroleum products in general):||75.080|
This method covers two procedures for the determination of total sulfur in petroleum products, including lubricating oils containing additives, and additive concentrates. The method is applicable to samples boiling above 350°F (177°C) and containing not less than 0.06 % sulfur. Chlorine in concentrations less than 1 % does not interfere. Nitrogen when present in excess of 0.1 % may interfere; the extent of such interference may be dependent on the type of nitrogen compound as well as the combustion conditions. The alkali and alkaline earth metals, as well as zinc, phosphorus, and lead, do not interfere.
Petroleum coke containing up to 8 % sulfur can be analyzed.
