5.1 This guide is intended for the developers or sponsors of new aviation gasolines or additives to describe the data requirements necessary to support the development of specifications for these new products by ASTM members. The ultimate goal of the data generated in accordance with this guide is to provide an understanding of the performance of the new fuel or additive within the property constraints and compositional bounds of the proposed specification criteria.
5.2 This guide is not an approval process. It is intended to describe test and analysis requirements necessary to generate data to support specification development. This guide does not address the approval process for ASTM International standards.
5.3 This guide will reduce the uncertainty and risk to developers or sponsors of new aviation gasolines or additives by describing the test and analysis requirements necessary to proceed with the development of an ASTM International specification for aviation gasoline or specification revision for an aviation gasoline additive.
5.4 This guide does not purport to specify an all-inclusive listing of test and analysis requirements to achieve ASTM International approval of a specification or specification revision. The final requirements will be dependent upon the specific formulation and performance of the candidate fuel and be determined by the ASTM International task forces and committees charged with overseeing the specification development.
5.5 This guide is intended to describe data to be used to make a determination of the suitability of the proposed fuel or additive for use on existing or future aircraft and engines, but not necessarily for use on all existing or future aircraft and engines.
5.6 This guide does not describe data requirements of other approving authorities, such as national aviation regulatory authorities, or of other organizations or industry associations. However, the data generated in the conduct of the procedure may be useful for other purposes or other organizations.
5.7 Over 2008201;000 piston-engine aircraft rely on Specification D910 lead-containing aviation gasoline (avgas) for safe operation. There has been an increase in the research and development of alternatives to Specification D910 gasolines as a result of environmental and economic concerns.
1.1 This guide provides procedures to develop data for use in research reports for new aviation gasolines or new aviation gasoline additives.
1.2 This data is intended to be used by the ASTM subcommittee to make a determination of the suitability of the fuel for use as an aviation fuel in either a fleet-wide or limited capacity, and to make a determination that the proposed properties and criteria in the associated standard specification provide the necessary controls to ensure this fuel maintains this suitability during high-volume production.
