3、vers Grades UL82 and UL87 unleaded aviation gasolines, which are defined by this specification andare only for use in engines and associated aircraft that are specifically approved by the engine and aircraft manufacturers, andcertified by the National Certifying Agencies to use these fuels. Componen
4、ts containing hetro-atoms (oxygenates) may be presentwithin the limits specified.1.2 A fuel may be certified to meet this specification by a producer as Grade UL82 or UL87 aviation gasoline only if blendedfrom component(s) approved for use in these grades of aviation gasoline by the refiner(s) of su
5、ch components, because only therefiner(s) can attest to the component source and processing, absence of contamination, and the additives used and theirconcentrations. Consequently, re-classifying of any other product to Grade UL82 or Grade UL87 aviation gasoline does not meetthis specification.1.3 A
