Aviation fuels, aviation turbine fuels, and aviation gasoline are important fuels in terms of worldwide commerce, and ASTM International is the preeminent standards-writing body issuing specifications for these fuels. Chapter 8 of ASTM Manual 69 describes in detail the specifications ASTM D1655 Standard Specification for Aviation Turbine Fuel and ASTM D910 Standard Specification for Aviation Gasoline. Explanations are given on the meaning and intention of the paragraphs within these two specifications along with a detailed account of the rationale and purpose of the specification property limits and the limits in the specifications being set to ensure the product is marketable and will perform satisfactorily as intended and over the wide range of temperatures and pressure variations encountered with aircraft altitude changes. The limits on the properties must take into account both modern and older aircraft and the derivation and history behind the limits is also discussed. There is also an explanation of the operation of an aviation turbine engine and the accompanying fuel supply system.
Somewhere in the world an aircraft is refueled every second with an acceptable fuel that must meet exacting standards. Two such standards are ASTM D1655, Standard Specification for Aviation Turbine Fuel, and ASTM D910, Standard Specification for Aviation Gasolines. In many parts of the world, if an aviation fuel does not meet these ASTM specifications it is not acceptable.
