    Background Information: Six (6) ASTM research reports; Three (3) from previous inter-laboratory studies (ILSs) and three (3) from other investigations, have led to the current D5453 scope which allows the analysis of a wide and comprehensive range of petroleum materials and products. The current D5453 standard test method (STM) has a robust precision statement for all covered materials with concentrations of sulfur less than 400 mg/kg. Consequently D5453 is extensively referenced in many (public and private) petroleum material specifications and regulatory requirements. Reason for this Ballot: A seven (7) lab inter-laboratory study (ILS) done by the Western States Petroleum Association (WSPA) in 2005 (that will be documented in an ASTM D.02 research report) found that reduced sulfur result variance described as precision, repeatability (r) and reproducibility (R), can be achieved for reformulated gasoline (RFG), ultra-low level sulfur diesel (ULSD) and RFG/ethanol blends containing sulfur contamination less than 50 mg/kg. This tightened precision was achieved when the use of a direct injection sample inlet system, an automatic sample injector and various performance based measurement system (PBMS) procedures are made mandatory. Proposed Action: This ballot proposes to revise D5453 by inserting an appendix that can allow the user to follow an alternate set of mandatory STM requirements. When followed the alternate requirements can yield a result precision for RFG, ULSD and RFG/ethanol blends with sulfur concentrations that are greater than 10 and less than 50 mg/kg that are tighter than those described in section 15 of D5453. Accordingly, Section 1 (Scope) and 15 (Precision and Bias) are revised to advise the D5453 STM user of the availability of the non-mandatory appendix. For the fuel materials described, the appendix can be required for various specification and regulatory purposes. As such, the ballot revision is intended to define the alternate mandatory functional requirements described in the appendix without being overly prescriptive for the D5453 stakeholder.
