5、xpertise to give appropriate data for review. Because of thediversity of aviation hardware and potential variation infuel/additive formulations, not every aspect may be encom-passed and further work may be required. Therefore, additionaldata beyond that described in this guide may be requested bythe
6、 ASTM task force, Subcommittee J, or Committee D02upon review of the specific composition, performance, or othercharacteristics of the candidate fuel or additive.1.4 While it is beyond the scope of this guide, investigationof the future health and environmental impacts of the newaviation gasoline or
7、 new aviation gasoline additive and therequirements of environmental agencies is recommended.1.5 The values stated in SI units are to be regarded asstandard.1.5.1 Some industry standard methodologies utilize impe-rial units as their primary system.1.6 This standard does not purport to address all of
