SCOPE
1.1 This specification covers formulating specifications for purchases of a high-octane (MON) unleaded fuel under contract and is intended solely for use by purchasing agencies.2
1.2 This specification defines a specific type of high-octane (MON) unleaded fuel for use as an aviation spark-ignition fuel. It does not include all fuels satisfactory for reciprocating aviation engines. Certain equipment or conditions of use may permit a wider, or require a narrower, range of characteristics than is shown by this specification.
1.3 This specification, unless otherwise provided, prescribes the required properties of unleaded fuel at the time and place of delivery.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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 and health practices and determine the applicability of regulatory limitations prior to use.

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 VP and 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.
