ASTM D3246: Standard Test Method for Sulfur in Petroleum Gas by Oxidative Microcoulometry.
Trace quantities of Sulfur compounds in hydrocarbon products can be harmful to many catalytic chemical processes in which these products are used. Maximum permissible levels of Total Sulfur are normally included in specifications for such hydrocarbons. It is recommended that this test method be used to provide a basis for agreement between two laboratories when the determination of Sulfur in hydrocarbon gases is important.
This test method covers determination of Sulfur in the range from 1.5 to 100 mg/kg (ppm by mass) by weight in hydrocarbon products that are gaseous at normal room temperature and pressure.
