Features & Benefits
This standard is a qualitative mixture of various gasoline and refinery materials prepared to provide nearly every component that may be encountered in feedstock and finished gasolines. Some oxygenates have been added to allow this blend to be used by refineries for Detailed Hydrocarbon Analysis (DHA) method setup and to fulfill requirements such as ASTM Methods D6729, D6730, and D6733.
