Standard Test Method for Sulfur in Gasoline by Wavelength Dispersive X-ray Fluorescence (Withdrawn 1999)

1999-12-10 /Withdrawn
No replacement

1.1 This test method covers the quantitative determination of total sulfur in gasoline and gasoline-oxygenate blends. The Pooled Limit of Quantitation (PLOQ) was determined to be 15 mg/kg. Therefore, the practical range for this test method is 15 to 940 mg/kg.

Note 1-This concentration range is based on that used in the interlaboratory round robin as reported in RR:D02-XXXX. That report shows that the range of sulfur in the round robin samples was 1.5 to 940 mg/kg but that below 15 mg/kg the reproducibility approaches 100% of the concentration.

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

1.3 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 to determine the applicability of regulatory limitations prior to use. For specific hazard information, see Note 2.
