ASTM SULFUR METHODOLOGY STUDIED AS ULSD, NEW TIER 2 LIMITS APPROACH

摘要

ASTM members meeting during the week of Dec. 4 will take up the timely topic of sulfur methodology. A task group has been working to improve ASTM D 2622-03, which measures fuel sulfur by wavelength dispersive X-ray fluorescence spectrometry. There are questions about the method's capability to measure fuel sulfur at the low levels required by the U.S. EPA's clean fuels rules next year.
