On June 22, ASTM will hold a workshop on State-of-the-Art Analytical Testing Methodologies for Improving the Analysis of Hydrocarbon Types for Naphthas, Jet Fuel and Diesel Fuel Range Streams. Workshop topics will include techniques using chromatography and/or mass spectrometry etc. Appropriate methodologies may be developed further by ASTM sections to either improve existing ASTM test methods or develop new test methods.
