Yes, the current version, ASTM method D-1319-93, is the regulatory method for olefins and may be used as an alternate for aromatics until January 1, 1997. For aromatics, it must also be correlated to the GC-MS method. Correlation to another laboratory's GC-MS is acceptable. Each D-1319 analysis system must show correlation since the method is operator dependent.(7/1/94)
