1、Designation: D6227 12D6227 14 An American National StandardStandard Specification forUnleaded Aviation Gasoline Containing a Non-hydrocarbonComponent1This standard is issued under the fixed designation D6227; the number immediately following the designation indicates the year oforiginal adoption or,

2、 in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers Grades UL82 and UL87 unleaded aviation gasolines, whi

4、n the limits specified.1.2 A fuel may be certified to meet this specification by a producer as Grade UL82 or UL87 aviation gasoline only if blendedfrom component(s) approved for use in these grades of aviation gasoline by the refiner(s) of such components, because only therefiner(s) can attest to th

5、e component source and processing, absence of contamination, and the additives used and theirconcentrations. Consequently, reclassifying of any other product to Grade UL82 or Grade UL87 aviation gasoline does not meetthis specification.1.3 Appendix X1 contains an explanation for the rationale of the
