22、 D614 (Discon-tinued 1970). A table for converting octane/performance numbers ob-tained by Test Method D2700 motor method into aviation ratings was lastpublished in Specification D91094 in the 1995 Annual Book of ASTMStandards, Vol 05.01.5.2 Grades 100, 100LL, and 100VLL represent aviationgasolines

23、identical in minimum antiknock quality but differingin maximum lead content and color.

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 vendor, tetraethyl lead antiknock mixture may bediluted with 20 mass percent of a mixed aromatic sol

29、venthaving a minimum flash point of 60 C according to TestMethods D93 when the product is to be handled in coldclimates. The TEL content of the dilute product is reduced to49 mass percent, so that the amount of antiknock additive mustbe adjusted to achieve the necessary lead level. The diluteproduct

30、 still delivers two bromine 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 shall be essentially 1,4-dialkylaminoanthraquinone.6.2.2.2 The only yellow dyes that

31、 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 finishedgasoline shall be essentially alkyl derivatives of azobenzene-4-azo-2-naphthol.6.3
