ASTM D 6920 : 2013

1.1This test method covers the determination of total sulfur in liquid hydrocarbons, boiling in the range from approximately 25 to 400°C, with viscosities between approximately 0.2 and 10 cSt (mm/S) at room temperature. This test method is applicable to naphthas, distillates, and motor fuels such as gasolines, reformulated gasolines, gasohols, diesels and biodiesels containing approximately 1 to 100 mg/kg total sulfur in gasoline type products, and approximately 1 to 40 mg/kg sulfur in diesel type products.

1.2The detector response for this technique within the scope of this test method is linear with sulfur concentration.

1.3Based on interlaboratory study, the pooled limit of quantitation of this test method is 3 mg/kg for gasoline and <0.5 mg/kg for diesel samples.

1.4This test method meets the U.S. EPA requirements for measuring sulfur in ultra low sulfur diesel fuels by the designated Test Method D6428, as published in the U.S. Federal Register § 80.520(a)(1).

1.5The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6This 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 hazard statements, see Sections 8 and 9.
