1. Rationale
A motion was passed at the June 26, 2012 ASTM Subcommittee D02.A meeting to ballot the addition of D7220 - Sulfur in Automotive, Heating, and Jet Fuels by Monochromatic Energy Dispersive X-ray Fluorescence Spectrometry to D4814 Standard Specification for Automotive Spark-Ignition Engine Fuel as an alternative sulfur determination test method. Rationale: A large inter-laboratory study (ILS-628) was conducted in Subcommittee D02.03 (Elemental Analysis) in 2010. In this study, D7220 tested 8 gasoline materials that included natural (straight-run) and reformulated (oxygenated) spark-ignition engine fuels. The precision (r & R) obtained is shown in comparison to two commonly used D4814 test methods in the following Table 1.
