Standard Test Method for Sulfur in Gasoline by Energy-Dispersive X-ray Fluorescence Spectrometry (Withdrawn 2009)

Scope

1.1 This test method covers the measurement of sulfur in nonleaded gasoline and gasoline-oxygenate blends. The applicable concentration range is 48 to 1000 mg/kg sulfur.

1.2 The values stated in SI units are to be regarded as the standard. The preferred concentration units are mg/kg sulfur.

1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Sections 5 and 7.

Significance and Use

This test method provides a means of quantifying sulfur content in gasoline. It can be referenced in specification documents as a means to determine if the material meets the desired sulfur content. It is a rapid and precise measurement of total sulfur in petroleum products with a minimum of sample preparation.

The quality of gasoline is related to the amount of sulfur present. Knowledge of sulfur concentration is necessary for processing purposes. There are also regulations promulgated in federal, state, and local agencies that restrict the amount of sulfur present in gasoline as it affects performance characteristics and potential corrosion problems and emission levels. During combustion, the sulfur content in fuel affects SOx emissions, which degrade air quality. Certain jurisdictions may restrict the amount of sulfur in gasoline to prevent or limit pollution to the environment.
