scope:

This standard specifies a method for the determination of total sulfur in petroleum products, natural gas and olefins. The method may be applied to products having sulfur contents in the range 1 to 10000 mg/kg and is particularly suitable for distillates with total sulfur contents of less than 300 mg/kg. Test samples which are viscous, highly aromatic, or high sulfur content may be first dilluted with a sulfur-free solvent. The method can be used for the determination of the total sulfur content of natural and refinery gases, also for substances supplied to the burner in the liquid state and for the determination of volatile sulfur in substances supplied to the burner in the gaseous state after vaporization from the liquid phase. It is not suitable for the determination of sulfur in heavy-duty engine oils. For the determination of sulfur in light olefins, see clause 13, special case.
