Abstract
The Environmental Protection Agency (EPA) is taking action to make certain fuel testing requirements more consistent and up-to-date by having refiners and laboratories use the most current version of an American Society of Testing and Materials (ASTM) analytical test method. Specifically, we are updating an ASTM designated analytical test method, ASTM D 1319 to the most recent 2002a version which when adopted will supersede earlier versions of this method in EPA's motor vehicle fuel regulations. This method is designated in EPA regulations for measuring chemical compositions in reformulated gasoline (RFG), conventional gasoline (CG), and diesel fuel, specifically aromatics and olefins in CG and RFG and aromatics in diesel fuel. These updates allow for more consistent use of the same methodology across EPA motor vehicle fuel regulations and incorporate improvements in the test method procedures that will ensure better operation.
