ASTM D6615-25

This specification covers the use of purchasing agencies in formulating specifications for purchases of aviation turbine fuel under contract. This specification defines type Jet B wide-cut aviation turbine fuel intended for use in aircraft that are certified to use such fuel. This fuel has advantages for operations in very low temperature environments compared with other fuels. The aviation turbine fuel shall consist of blends of refined hydrocarbons derived from crude petroleum, natural gasoline, or blends thereof with synthetic hydrocarbons. Additives such as antioxidants, metal deactivator, electrical conductivity additive, leak detection additive, and other additives including biocidal additive and fuel system icing inhibitor, may be added to the aviation turbine fuel in the amount and of the composition specified. The aviation turbine fuel shall conform to the requirements prescribed for the following: aromatics, mercaptan sulfur content, sulfur content, distillation temperature, distillation residue, distillation loss, density, vapor pressure, freezing point, net heat of combustion, smoke point and naphthalene content, copper strip corrosion, thermal stability such as filter pressure drop and tube deposits, existent gum, electrical conductivity, and microseparometer rating. The test methods for determining conformance to these specified requirements are given.
