INTRODUCTION
This new test fuel specification is for a high-octane unleaded fuel to be used for gathering data
toward a commercial research report and specification on an unleaded high-octane aviation gasoline.
A new high-octane unleaded test fuel has been developed which maintains the key performance
parameters of existing reciprocating aircraft engines. The two essential performance parameters of
MON and VP are inversely related with respect to composition and thus can uniquely define a
composition range of the two components. The values for VPand MON in Table 1 reflect the limiting
values of the two components. The binary fuel exhibits a higher volumetric energy density (net heat
of combustion times density) which is of great performance interest, although not explicitly stated in
Table 1. The distillation parameters reflect the binary compositional effects. This is an unleaded fuel,
so the limit of TEL in Table 1 is the same as is used in Specification D4814 for mogas and is meant
to mitigate unintentional contamination by TEL. Lastly, references to dyes remain in the specification
so that test groups may use them as necessary.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
