1.1 This testmethod covers the determination oftotal sulfur in liquidhydrocarbons, boiling inthe range from approximately 25°C to 400°C, with viscosities between approximately
0.2 and 10 cSt (mm IS) atroom 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.
1.2 The detector response for this technique within the scope of this test method is linear with sulfur concentration.
1.3 Based on interlaboratory study, the pooled limit of quantitation of this method is 3 mg/kg for gasoline and <0.5 mg/kg for diesel samples.
1.4 This method meets the U. S. EPA requirements for measuring sulfur in ultra low sulfur diesel fuels by the designated method D 6428, as published in the U. S. Federal Register § 80.520(a)(1).
1.5 This standard does notpurport to address all ofthe safety concerns, ifany, associated with its use. It is the responsibility ofthe user ofthis standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 9, and Notes 2-4 and Note 7.
