1.1 This standard practice provides procedures to develop data for use in research reports for new aviation turbine fuels, changes to existing aviation turbine fuels, or new aviation turbine fuel additives. These research reports are intended to support the development and issuance of new specifications or specification revisions for these products. This standard practice has also been used to evaluate the effect of incidental materials on jet fuel properties and performance.
1.2 The procedures, tests, and selection of materials detailed in this practice are based on industry expertise to provide the necessary data to determine if the new or changed fuel or additive is suitable for use on existing aircraft and engines and for use in the current aviation operational and supply infrastructure. As such, it is primarily intended for the evaluation of drop-in fuels, but it can also be used for the evaluation of other fuels.
1.3 Because of the diversity of aviation hardware and potential variation in fuel/additive formulations, not every aspect may be fully covered and further work may be required. Therefore, additional data beyond that described in this practice may be requested by the ASTM task force, Subcommittee J, or Committee D02 upon review of the specific composition, performance, or other characteristics of the candidate fuel or additive.
1.4 Units of measure throughout this practice are stated in International System of Units (SI) unless the test method specifies non-SI units.
1.5 This 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.
1.6 This 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.
5.1 This practice is intended to describe the data requirements necessary to support the review of new aviation turbine fuels or additives by ASTM members for the developers or sponsors of these new products.
5.2 Its purpose is to guide the sponsor of a new fuel or new fuel additive through a defined evaluation process that includes the prerequisite testing and required periodic reviews with the subcommittee members. This practice provides a basis for calculating the volume of additive or fuel required for assessment, insight into the cost associated with taking a new fuel or new fuel additive through the evaluation process, and a defined path forward for introducing a new technology for the benefit of the aviation community.
5.3 The allocation of resources necessary to support the full scope of the evaluation process is the responsibility of the sponsor of the new fuel or fuel additive. This will include laboratory, rig, or engine tests, if required, as well as support of OEM activities such as the Phase 1 and 2 reviews.
5.4 This process may also be used to assess the impact of changes to fuels due to changes in production methods and/or changes during transportation. An example is the assessment of the impact of incidental materials on fuel properties. In the context of Practice D4054, incidental materials shall be considered as an additive.
5.5 This guide is not an approval process. It is intended to describe test and analysis requirements necessary to generate data to support specification revision or development. This guide does not address the approval process for ASTM International standards.
5.6 This guide does not purport to specify an all-inclusive listing of test and analysis requirements to achieve ASTM International issuance of a specification or specification revision. The final requirements will be dependent upon the specific formulation and performance of the candidate fuel or additive and be determined by the ASTM International task groups and committees charged with overseeing the specification development.
5.7 Neither the generation of data and issuance of a research report described in this practice, nor the ultimate issuance of a new or revised ASTM fuel specification based on that data, constitutes approval to use the new or changed fuel or new additive on civil aircraft. As described in Appendix X2, the OEMs will conduct an internal review process in coordination with their aviation regulatory authorities to determine if the new fuel or additive is acceptable for use on each of their respective products. Only upon successful completion of this OEM internal review will the new fuel or additive be permitted for use on civil aircraft.
5.8 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, it is expected that the data generated in the conduct of the procedure will be used by the OEMs and national aviation regulatory authorities to support their internal approval processes (see Appendix X2) and may be useful for other purposes or other organizations.
