20、dentifies the difference forengines that have a low tolerance to lead.NOTE 2Listing of, and requirements for, Avgas Grades 91/96, 108/135 and 115/145 appeared in the 1967 version of this specification. U.S.Military Specification MIL-G-5572F, dated January 24, 1978 (withdrawnMarch 22, 1988), also cov
21、ers grade 115/145 aviation gasoline, and isavailable as a research report.45.3 Although the grade designations show only a singleoctane rating for each grade, they must meet a minimum leanmixture motor rating and a minimum rich mixture superchargerating (see X1.2.2).6. Materials and Manufacture6.1 A
22、viation gasoline, except as otherwise specified in thisspecification, shall consist of blends of refined hydrocarbonsderived from crude petroleum, natural gasoline, or blends,thereof, with synthetic hydrocarbons or aromatic hydrocar-bons, or both.6.2 AdditivesMandatory, shall be added to each grade
23、ofaviation gasoline in the amount and of the compositionspecified in the following list of approved materials.6.2.1 Tetraethyl Lead, shall be added in the form of anantiknock mixture containing not less than 61 mass % oftetraethyl lead and sufficient ethylene dibromide to provide twobromine atoms pe
24、r atom of lead. The balance shall contain noadded ingredients other than kerosine, an approved oxidationinhibitor, and blue dye, as specified herein. The maximumconcentration limit for each grade of gasoline is specified inTable 1.6.2.1.1 If mutually agreed upon by the fuel producer andadditive vend
25、or, tetraethyl lead antiknock mixture may bediluted with 20 mass % of a mixed aromatic solvent having aminimum flash point of 60C according to Test Methods D93when the product is to be handled in cold climates. The TELcontent of the dilute product is reduced to 49 mass %, so thatthe amount of antikn
26、ock additive must be adjusted to achievethe necessary lead level. The dilute product still delivers twobromine atoms per atom of lead.6.2.2 DyesThe maximum concentration limits in eachgrade of gasoline are specified in Table 1.6.2.2.1 The only blue dye that shall be present in thefinished gasoline s
27、hall be essentially 1,4-dialkylaminoanthraquinone.6.2.2.2 The only yellow dyes that shall be present in thefinished gasoline shall be essentiallyp-diethylaminoazobenzene (Color Index No. 11021) or 1,3-benzenediol 2,4-bis (alkylphenyl)azo-.6.2.2.3 The only red dye that shall be present in the finishe

29、t and of the composition specified inthe following list of approved materials.5The quantities andtypes shall be declared by the manufacturer. Additives addedafter the point of manufacture shall also be declared.6.3.1 AntioxidantsThe following oxidation inhibitors maybe added to the gasoline separate
