ASTM D 8076 : 2024

1.1This specification covers the requirements of 95, 98, and 100 research octane number (RON) test fuels suitable for spark-ignition engines to be utilized in ground vehicles.

1.2The fuels covered in this specification may contain oxygenates, such as alcohols and ethers, up to 50 % by volume. This specification covers fuels that may contain both fossil and bio-derived components.

1.3This specification provides a description of 95, 98, and 100 RON test fuels for automotive spark-ignition engines. Not all these fuels are currently in the marketplace, but they are being developed and require defined standard test fuels. These fuels could become available in the marketplace if/when such engines are introduced in commerce. The specification is under continuous review, which can result in revisions based on changes in fuel, automotive requirements, or test methods, or a combination thereof. All users of this specification, therefore, should refer to the latest edition.

1.4The values stated in SI units are the standard.

1.5This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
