1.1 This test method covers the determination of total sulfur in petroleum and petroleum products that are single-phase and either liquid at ambient conditions, liquefiable with moderate heat, or soluble in hydrocarbon solvents. These materials can include diesel fuel, jet fuel, kerosene, other distillate oil, naphtha, residual oil, lubricating base oil, hydraulic oil, crude oil, unleaded gasoline, gasohol and biodiesel. 1.2 An estimate of this methods pooled limit of quantitation (PLOQ) is 3 mg/kg as calculated by the procedures in Practice D 6259. 1.2.1 The values of the limit of quantitation (LOQ) and method precision for a specific laboratorys instrument depends on instrument source power (low or high power), sample type, and the practices established by the laboratory to perform the method. 1.3 Samples containing more than 4.6 mass % sulfur should be diluted to bring the sulfur concentration of the diluted material within the scope of this test method. Samples that are diluted can have higher errors than indicated in Section than non-diluted samples. 1.4 Volatile samples (such as high vapor pressure gasolines or light hydrocarbons) may not meet the stated precision because of selective loss of light materials during the analysis. 1.5 A fundamental assumption in this test method is that the standard and sample matrices are well matched, or that the matrix differences are accounted for (see 12.2). Matrix mismatch can be caused by C/H ratio differences between samples and standards or by the presence of other interfering heteroatoms or species (see Table 1). 1.6 The values stated in SI units are to be regarded as the standard. The values given in parenthess are for informaiton only. 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 applicab ....(abbreviated)
