When gasoline engines became more powerful in the 1920s, it was discovered that the most extreme knocking effect was produced by a fuel composed of pure normal heptane, while the least knocking effect was produced by pure isooctane. This discovery led to the development of the octane scale for defining gasoline quality.

Risk Assessment

Substances on European priority lists must undergo an in-depth risk assessment covering the risks posed by the priority chemical to man (covering workers, consumers and man exposed via the environment) and the environment (covering the terrestrial, aquatic and atmospheric eco-systems and accumulation through the food chain). This risk assessment follows the framework set out in European Commission Regulation (EC) 1488/94 and implemented in the detailed Technical Guidance Documents (TGD) on Risk Assessment for New and Existing Substances. The first draft of the risk assessment reports are written by the Member States which act as "rapporteurs". The Commission mediates the meetings, which attempt to reach consensus on the conclusions of the risk assessments.
