English term or phrase:SDA grades
Two SDA grades are available, Stadis 450 and Stadis 425. Stadis 450 is the only grade approved for use in Jet Fuels. Stadis 425 is an older version and is no longer aviation-approved. For harmonisation and to prevent misuse, refineries normally use only Stadis 450.
