CONCAWE issues guidelines on gasoline volatility aspects for year 2000 EN 228 standard

01 Apr 1999

Gasoline volatility specifications are defined in volatility classes in the European Standard EN 228. CEN member countries have selected up to three volatility classes to satisfy the driveability requirements for their market based on regional climatic variations over the year. The new EU Fuels Directive 98/70/EC defines the environmentally relevant specifications and thus affects fuel composition. Consequently, other specifications, especially volatility classes, have also to be reviewed. To accommodate new legal specifications and other technical aspects, CEN is revising the year 2000 EN 228 specifications accordingly, which were established for the first time as a European gasoline standard in 1993.
