Standard Test Method for
Thermal Stability of Aviation Turbine Fuels?
This standard is issued under the fixed designation D 1660; the number immediately following the designation indicafes the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (E) indicates an editorial change since the last revision or reapproval.
This test method has been adopted for tise by government agencies to replace Method 3464 of Federal Test Method Standard Nu. 791b.
