The color identifies
23、 the difference for engines that have a low tolerance to lead.NOTE 2Listing of, and requirements for, Avgas Grades 91/98, 108/135 and 115/145 appeared in the 1967 version of this specification. U.S. MilitarySpecification MIL-G-5572F, dated January 24, 1978 (withdrawn March 22, 1988), also covers gra
24、de 115/145 aviation gasoline, and is available as aresearch report.45.3 Although the grade designations show only a single octane rating for each grade, they shall meet a minimum lean mixturemotor rating and a minimum rich mixture supercharge rating (see X1.2.2).6. Materials and Manufacture6.1 Aviat
25、ion gasoline, except as otherwise specified in this specification, shall consist of blends of refined hydrocarbons derivedfrom crude petroleum, natural gasoline, or blends, thereof, with synthetic hydrocarbons or aromatic hydrocarbons, or both.6.2 AdditivesMandatory, shall be added to each grade of
26、aviation gasoline in the amount and of the composition specified inthe following list of approved materials.6.2.1 Tetraethyl Lead, shall be added in the form of an antiknock mixture containing not less than 61 mass percent of tetraethyllead and sufficient ethylene dibromide to provide two bromine at
27、oms per atom of lead. The balance shall contain no added4 Supporting data have been filed at ASTM International Headquarters and may be obtained by requesting Research Report RR:D02-1255.D910 162ingredients other than kerosine, an approved oxidation inhibitor, and blue dye, as specified herein. The
28、maximum concentrationlimit for each grade of gasoline is specified in Table 1.6.2.1.1 If mutually agreed upon by the fuel producer and additive vendor, tetraethyl lead antiknock mixture may be diluted with20 mass percent of a mixed aromatic solvent having a minimum flash point of 60 C according to T
29、est Methods D93 when theproduct is to be handled in cold climates. The TEL content of the dilute product is reduced to 49 mass percent, so that the amountof antiknock additive must be adjusted to achieve the necessary lead level. The dilute product still delivers two bromine atoms peratom of lead.6.
30、2.2 DyesThe maximum concentration limits in each grade of gasoline are specified in Table 1.6.2.2.1 The only blue dye that shall be present in the finished gasoline shall be essentially 1,4-dialkylaminoanthraquinone.6.2.2.2 The only yellow dyes that shall be present in the finished gasoline shall be
31、 essentially p-diethylaminoazobenzene (ColorIndex 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 finished gasoline shall be essentially alkyl derivatives of azobenzene-4-azo-2-naphthol.6.2.2.4 The only orange dye that shall be present in
32、 the finished gasoline shall be essentially benzene-azo-2-napthol (ColorIndex No. 12055).6.3 AdditivesThese may be added to each grade of aviation gasoline in the amount and of the composition specified in thefollowing list of approved materials.5 The quantities and types shall be declared by the ma
33、nufacturer. Additives added after thepoint of manufacture shall also be declared.6.3.1 AntioxidantsThe following oxidation inhibitors may be added to the gasoline separately, or in combination, in totalconcentration not to exceed 12 mg of inhibitor (not including weight of solvent) per litre of fuel
