適用范圍：1.1 This method covers two procedures for the determination of total sulphur in petroleum products, including lubricating oils containing additives, and additive concentrates. The method is applicable to samples boiling above 177°C (350°F) and containing not less than 0.06% sulphur. 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, phosphorous, and lead, do not interfere.1.2 Petroleum coke containing up to 8% sulphur can be analyzed.
