1.1 This test method covers the determination of sulfur concentration in the range from 3.0 to 1000 mg/kg in light liquid hydrocarbons boiling in the range from 26 to 274°C (80 to 525°F).

1.2 Other materials falling within the distillation range specified in , but having sulfur concentrations above 1000 mg/kg, may be tested using appropriate dilutions to bring them within the specified limit. In addition, sample types that may be outside the specified distillation range, such as diesels and biodiesels, may be analyzed by this test method.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only. The preferred units are milligrams per kilogram (mg/kg).

1.4 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 hazard statements, see Sections 7-9.
